00:00:00.080 --> 00:00:07.120
the internet really is a curious thing because this whole idea started as a

00:00:04.319 --> 00:00:10.960
joke to celebrate mr beast having 20 million subscribers he should plant 20

00:00:09.599 --> 00:00:16.960
million trees it's a crazy idea 20 million is a lot of

00:00:13.440 --> 00:00:19.039
trees but then the idea took root mark

00:00:16.960 --> 00:00:24.480
rober got involved and then a bunch of other youtubers got involved and

00:00:22.560 --> 00:00:28.320
it looks like we're gonna do it so the arbor day foundation are experts when it

00:00:26.240 --> 00:00:32.160
comes to planting trees quickly and efficiently and what's really exciting

00:00:30.160 --> 00:00:37.040
is that they have agreed that during this fundraiser for every dollar just

00:00:34.880 --> 00:00:42.640
one dollar we raise they are going to plant a tree so naturally then our goal

00:00:39.280 --> 00:00:45.520
is to raise 19 million 999

00:00:42.640 --> 00:00:50.000
600 and twenty dollars why that number you might say

00:00:47.360 --> 00:00:53.760
well because in addition to making our own contribution to the campaign which

00:00:51.920 --> 00:00:58.079
you can find the full details for down below guys please do give this is a

00:00:56.079 --> 00:01:03.080
really important cause we are going to be getting our boots and our hands dirty

00:01:00.960 --> 00:01:07.840
by planting this 380 trees of course though this is lined

00:01:05.760 --> 00:01:11.920
as tech tips not some like you know shovel and you know

00:01:09.840 --> 00:01:17.680
boots operations so we needed a techie way to plant trees meet the tree zuka

00:01:15.040 --> 00:01:23.119
this is our extremely detailed and super professional design for

00:01:20.720 --> 00:01:27.920
a tree planting cannon and i'm going to show you guys exactly how it works so

00:01:25.840 --> 00:01:33.360
step one is to load the trees the original design for the

00:01:29.920 --> 00:01:33.360
tree zooka was to

00:01:34.720 --> 00:01:40.400
damn i guess i can't really get that out anymore can i the original design for

00:01:38.320 --> 00:01:45.280
the tree zuka allowed for us to shoot just one tree at a time but we figured

00:01:42.799 --> 00:01:49.280
hey if one is good then two must be twice as good step two

00:01:47.600 --> 00:01:52.880
is to load our combustion chamber at the back of the cannon with acetylene this

00:01:51.280 --> 00:01:57.360
is going to propel our trees at about 406 feet per second 40 feet per second

00:01:55.920 --> 00:02:02.159
lower than when it's classified as a firearm step 3 assume a comfortable

00:02:00.320 --> 00:02:08.119
firing position this thing's going to give some kick thanks to the potato

00:02:03.920 --> 00:02:08.119
that's also loaded into the barrel

00:02:08.560 --> 00:02:14.160
step four have someone you really trust

00:02:12.640 --> 00:02:17.160
whoa whoa

00:02:22.720 --> 00:02:29.680
okay the design might need a little work did you not warn me because you assumed

00:02:26.239 --> 00:02:29.680
i knew or to with me

00:02:30.400 --> 00:02:35.680
get a brand new virtual credit card number each time you use it when you

00:02:33.519 --> 00:02:41.680
shop with privacy click the link below and get five dollars off your first

00:02:37.200 --> 00:02:44.720
purchase that's like free money okay so

00:02:41.680 --> 00:02:47.840
obviously that wasn't gonna work

00:02:44.720 --> 00:02:50.319
but we have a new plan and by the end of

00:02:47.840 --> 00:02:54.080
this video the 400 sapling trees that we have loaded in the back of the truck are

00:02:52.080 --> 00:02:59.440
going to be embedded in the ground one way or another the conventional way

00:02:56.400 --> 00:03:01.280
to plant trees goes as follows

00:02:59.440 --> 00:03:04.400
you clear the debris from the area that you want to plant the tree dig a small

00:03:03.040 --> 00:03:07.519
hole oh man that's nice easy ground i'm

00:03:06.239 --> 00:03:12.959
barely even gonna have to dig a hole just like make a make a gap pretty much then

00:03:11.519 --> 00:03:20.080
unless your tree already has it integrated like ours does ours doesn't

00:03:16.000 --> 00:03:20.080
it doesn't so we need fertilizer then

00:03:21.280 --> 00:03:27.599
what's this you're going to want to insert some fertilizer into the hole this is some

00:03:25.200 --> 00:03:32.319
frozen daikon yeah there we go then you just put the

00:03:29.680 --> 00:03:36.080
tree into the hole level with the there yeah

00:03:33.519 --> 00:03:39.840
yeah replace any dirt that you moved and stomp all around it

00:03:37.760 --> 00:03:44.560
to pack the dirt back in so it's nice and supported and upright

00:03:42.239 --> 00:03:48.640
and that's it the job's done now in some places you can use this tube

00:03:46.879 --> 00:03:53.360
looking thing to assist in your tree planting endeavors but here in bc the

00:03:51.120 --> 00:03:57.680
tougher soil will jam them in an instant pretty much everyone we talked to said

00:03:54.799 --> 00:04:00.879
to just stick with a shovel great advice if you're some kind of cave

00:03:59.599 --> 00:04:05.280
we still think there's room for improvement for one using the shovel and

00:04:03.680 --> 00:04:10.640
planting the tree it's not super ergonomic you're going to be bending

00:04:07.120 --> 00:04:11.840
down constantly tiring yourself out who

00:04:10.640 --> 00:04:15.599
needs that and two there's a key component missing

00:04:14.640 --> 00:04:21.600
fun can you imagine how many people would sign up to plant trees if they did it

00:04:19.120 --> 00:04:21.600
like this

00:04:22.240 --> 00:04:27.440
everyone would sign up for tree planting if it was like this

00:04:25.840 --> 00:04:32.400
let's talk about the improvements we've made to our tree planting cannon design

00:04:29.919 --> 00:04:37.440
first we changed over from acetylene to compressed gas

00:04:33.919 --> 00:04:38.720
while acetylene does pack quite a punch

00:04:37.440 --> 00:04:44.479
it is well an extremely explosive gas and one

00:04:42.240 --> 00:04:48.880
of our key design goals here is to not die if something goes wrong

00:04:46.880 --> 00:04:54.479
our main inspiration came from bill chernoff who as far as we can tell owns

00:04:51.199 --> 00:04:56.000
the world's only potato chain gun and he

00:04:54.479 --> 00:04:59.440
was kind enough to give us some advice on how to make an air cannon like no

00:04:58.560 --> 00:05:06.080
other although we would have liked to create a magazine for automatic firing like his

00:05:03.600 --> 00:05:10.880
cannon it isn't necessary for us to shoot quite that fast and apparently his

00:05:08.960 --> 00:05:15.360
mechanism took a lot of tuning and prototyping to get just right so we

00:05:13.360 --> 00:05:18.000
decided for a simple breech style loading mechanism

00:05:16.880 --> 00:05:23.600
here we go which should still be fast enough for us

00:05:20.639 --> 00:05:26.880
to plant several trees per minute being able to reload quickly is no good

00:05:25.520 --> 00:05:32.400
though if you don't have the muscle to back it up meet the muscle

00:05:29.840 --> 00:05:39.919
this tank holds compressed nitrogen gas at 2 000 psi then our solenoid valve

00:05:36.479 --> 00:05:43.039
right here controls the flow

00:05:39.919 --> 00:05:45.759
here it is this mini tank right here

00:05:43.039 --> 00:05:51.199
then another solenoid valve at the end opens up to fire

00:05:48.000 --> 00:05:53.039
or as we call it make the fun happen

00:05:51.199 --> 00:05:57.759
both of these solenoids are controlled by this simple electrical box right here

00:05:56.080 --> 00:06:01.919
this little pressure release valve here will make sure that our pressure doesn't

00:05:59.360 --> 00:06:06.560
get over 300 psi the limit of our solenoid valves and although by swapping

00:06:04.720 --> 00:06:11.199
out a couple of components we could get much higher pressure i think you guys

00:06:08.800 --> 00:06:15.919
are going to agree that it's got quite enough punch as it is are we armed right

00:06:13.759 --> 00:06:15.919
now

00:06:16.880 --> 00:06:23.440
i'm firing my laser baby three two

00:06:20.800 --> 00:06:28.350
one wow

00:06:25.199 --> 00:06:30.000
well that potato disintegrated

00:06:30.000 --> 00:06:35.479
three two one go wow

00:06:36.240 --> 00:06:40.240
let's plant some trees shall we

00:06:42.639 --> 00:06:48.400
beautiful oh no i want to use the tube

00:06:45.680 --> 00:06:54.160
i want to use the tube nope you have to line up the two okay

00:06:50.080 --> 00:06:54.160
fine okay fire in the hole

00:07:00.160 --> 00:07:05.039
give her one more

00:07:03.520 --> 00:07:07.599
beautiful planted

00:07:09.039 --> 00:07:16.479
the actual amount of digging was basically zero and we've embedded our

00:07:14.160 --> 00:07:20.400
our bit of frozen zucchini here right next to the roots this thing is is

00:07:18.479 --> 00:07:23.759
perfectly positioned for success right now

00:07:21.759 --> 00:07:28.840
okay next round okay yep can i press the button this time sure can fire the hole

00:07:30.000 --> 00:07:34.960
finger is numb okay

00:07:33.039 --> 00:07:38.880
hold on let me just widen the white in the hole here a little bit

00:07:37.599 --> 00:07:41.919
gorgeous ah ain't that a thing of beauty ladies

00:07:40.800 --> 00:07:47.759
and gentlemen all right back it up

00:07:45.680 --> 00:07:50.720
wait does the turning serve any purpose oh you were just having fun

00:07:49.520 --> 00:07:56.800
okay all right so what all we got here is this uh potato potato beautiful a little

00:07:54.879 --> 00:08:00.000
bit of frozen potato in there put that potato in there you're only at

00:07:58.560 --> 00:08:03.599
like 90 psi right now you want to bring it around to like 250. oh

00:08:02.560 --> 00:08:06.240
there you go fire in the hole

00:08:06.319 --> 00:08:12.479
wow we definitely hit something that time

00:08:09.759 --> 00:08:17.039
yep that was that was a root to only do like 90 psi or so this 90 or so okay

00:08:15.039 --> 00:08:20.160
quick press armed and for the hole

00:08:20.560 --> 00:08:26.639
okay so i think the stem actually did end up a little damaged that time

00:08:24.560 --> 00:08:31.360
but uh okay let's try it let's try that again here let's go maybe six feet this

00:08:28.319 --> 00:08:32.479
way i love that this one's bullet shaped

00:08:31.360 --> 00:08:35.039
all right charging

00:08:36.000 --> 00:08:40.719
whoa get a tree in there wow look at that

00:08:39.760 --> 00:08:44.800
whoa this is so damn stupid let me just

00:08:42.800 --> 00:08:48.560
loosen you up a little bit here you might have to shift just a bit you got

00:08:46.720 --> 00:08:51.200
to use your sight there bud that's probably fine

00:08:52.880 --> 00:08:58.399
that ain't gonna heal she ain't gonna make it past the winner

00:08:56.240 --> 00:09:02.160
there we're still learning we're still ironing out the details let's uh let's

00:09:00.240 --> 00:09:07.440
do another what if we leaned the whole thing down and we muzzle loaded it

00:09:05.279 --> 00:09:11.440
so we put the pellet in from the end

00:09:08.959 --> 00:09:14.160
and then we put the tree in from here

00:09:12.480 --> 00:09:18.320
and then that way the pellet can kind of clear the path for the tree a little

00:09:15.680 --> 00:09:22.320
maybe i'm not that far up listen to this guy all like well we did the

00:09:20.080 --> 00:09:26.240
calculations and simulation and solid works

00:09:24.640 --> 00:09:30.560
it actually kind of worked minus like the tree dying yeah the like the uh the

00:09:28.640 --> 00:09:34.720
crater's about the right size so that actually brings us into something we had

00:09:32.320 --> 00:09:40.240
wanted to discuss in this video um lockheed martin had the idea of carpet

00:09:37.440 --> 00:09:43.680
bombing trees and youtube channel i did a thing actually made a great video

00:09:42.000 --> 00:09:46.959
about rocket trees and we liked the idea but our concern

00:09:45.839 --> 00:09:52.000
was that it was going to be pretty difficult even

00:09:49.360 --> 00:09:56.160
with the proposed solution of creating like a

00:09:53.320 --> 00:10:00.560
papier-mache or some kind of outer protective casing around each tree

00:09:58.640 --> 00:10:04.480
because it's just a lot of force

00:10:02.720 --> 00:10:07.040
also we didn't go that route because it would have been very time consuming to

00:10:06.080 --> 00:10:12.399
create 400 paper mache bullets overall we don't

00:10:10.160 --> 00:10:17.200
think that planting trees with a cannon actually makes a ton of sense especially

00:10:14.640 --> 00:10:20.160
because there's so much stuff that you have to drag around with you but we

00:10:18.640 --> 00:10:25.120
thought you guys might like some fun facts about our tree cannon uh it's got

00:10:22.560 --> 00:10:30.880
an approximate barrel velocity of 140 meters per second or 460 feet per second

00:10:28.079 --> 00:10:36.240
an ideal angle of launch of 36 degrees a distance without drag of over 1.5

00:10:33.600 --> 00:10:40.720
kilometers a distance with drag of about 600 meters i mean all of that is

00:10:38.640 --> 00:10:43.839
basically just a guess since it's hard to say how

00:10:41.920 --> 00:10:47.839
stable the flight of our projectile would be and

00:10:45.519 --> 00:10:52.880
how much you know a hypothetical tree could change the drag coefficient etc um

00:10:50.959 --> 00:10:56.640
but we think it's safe to say that our projectile could go anywhere between 300

00:10:55.120 --> 00:11:00.959
meters and one kilometer so this was clearly more

00:10:59.040 --> 00:11:04.880
about having fun than it was about making a practical tree cannon but i

00:11:03.120 --> 00:11:09.279
don't want that to distract from why this is so important in the amazon we've

00:11:07.440 --> 00:11:13.600
managed to destroy about half of the mature rainforests and tropical

00:11:11.600 --> 00:11:18.720
deforestation contributes a staggering 20 of world greenhouse gas emissions

00:11:16.320 --> 00:11:23.519
deforestation also has a wide variety of unpleasant effects like the land heats

00:11:21.120 --> 00:11:28.720
up faster without a forest soil without roots embedded in it erodes

00:11:25.680 --> 00:11:32.160
faster dries up faster and contains less

00:11:28.720 --> 00:11:33.920
nutrients for other plants oh and also

00:11:32.160 --> 00:11:38.480
any animals that used to live in a forest that's gone

00:11:35.680 --> 00:11:42.640
they're all dead now but the thing is we aren't planting trees in the amazon

00:11:40.560 --> 00:11:46.959
we're up in canada so you might wonder what's the point of planting trees here

00:11:45.040 --> 00:11:50.959
well half of the world's forest growth potential is actually found in just six

00:11:49.279 --> 00:11:54.560
countries with canada being third on that list and when you're concerned

00:11:52.959 --> 00:11:58.399
about things like air quality and climate change growing new forests is

00:11:56.480 --> 00:12:04.000
incredibly important no matter where it is a mature forest is roughly carbon

00:12:00.800 --> 00:12:06.720
neutral but as a new forest grows the

00:12:04.000 --> 00:12:11.600
carbon is stored in the freeze providing a total reduction in the overall carbon

00:12:09.200 --> 00:12:16.480
in the atmosphere worldwide that means that planting new forests in north

00:12:13.279 --> 00:12:18.480
america and russia is a really great way

00:12:16.480 --> 00:12:22.720
to combat climate change even if there are already plenty of forests there

00:12:20.720 --> 00:12:27.360
so get out there have some fun plant some trees

00:12:25.440 --> 00:12:31.839
and if you can or you don't feel like it that's fine

00:12:29.279 --> 00:12:34.800
too just go to teamtrees.org to donate for every dollar that you guys

00:12:33.200 --> 00:12:38.800
contribute Linus media group is going to match you up to ten thousand dollars

00:12:37.120 --> 00:12:42.959
and since we have no way of tracking how much you guys contribute i guess we'll

00:12:40.720 --> 00:12:48.320
just write the check today and go with the honor system here

00:12:46.240 --> 00:12:53.800
speaking of honorable my transition to our sponsor for today's

00:12:50.800 --> 00:12:53.800
video

00:12:54.000 --> 00:13:00.560
knock knock hopefully it's not those guys

00:12:58.560 --> 00:13:05.600
with the ring doorbell kit you can pre-screen anyone who's at your front

00:13:02.959 --> 00:13:10.480
door because guys the year is not 1990 anymore and those peoples are so passe

00:13:08.959 --> 00:13:15.360
the ring kit includes their video doorbell 2 spotlight cam battery and

00:13:12.959 --> 00:13:19.519
solar security sign the video doorbell 2 has a motion sensor camera with

00:13:16.880 --> 00:13:23.839
