the internet really is a curious thing because this whole idea started as a
joke to celebrate mr beast having 20 million subscribers he should plant 20
million trees it's a crazy idea 20 million is a lot of
trees but then the idea took root mark
rober got involved and then a bunch of other youtubers got involved and
it looks like we're gonna do it so the arbor day foundation are experts when it
comes to planting trees quickly and efficiently and what's really exciting
is that they have agreed that during this fundraiser for every dollar just
one dollar we raise they are going to plant a tree so naturally then our goal
is to raise 19 million 999
600 and twenty dollars why that number you might say
well because in addition to making our own contribution to the campaign which
you can find the full details for down below guys please do give this is a
really important cause we are going to be getting our boots and our hands dirty
by planting this 380 trees of course though this is lined
as tech tips not some like you know shovel and you know
boots operations so we needed a techie way to plant trees meet the tree zuka
this is our extremely detailed and super professional design for
a tree planting cannon and i'm going to show you guys exactly how it works so
step one is to load the trees the original design for the
tree zooka was to
damn i guess i can't really get that out anymore can i the original design for
the tree zuka allowed for us to shoot just one tree at a time but we figured
hey if one is good then two must be twice as good step two
is to load our combustion chamber at the back of the cannon with acetylene this
is going to propel our trees at about 406 feet per second 40 feet per second
lower than when it's classified as a firearm step 3 assume a comfortable
firing position this thing's going to give some kick thanks to the potato
that's also loaded into the barrel
step four have someone you really trust
whoa whoa
okay the design might need a little work did you not warn me because you assumed
i knew or to with me
get a brand new virtual credit card number each time you use it when you
shop with privacy click the link below and get five dollars off your first
purchase that's like free money okay so
obviously that wasn't gonna work
but we have a new plan and by the end of
this video the 400 sapling trees that we have loaded in the back of the truck are
going to be embedded in the ground one way or another the conventional way
to plant trees goes as follows
you clear the debris from the area that you want to plant the tree dig a small
hole oh man that's nice easy ground i'm
barely even gonna have to dig a hole just like make a make a gap pretty much then
unless your tree already has it integrated like ours does ours doesn't
it doesn't so we need fertilizer then
what's this you're going to want to insert some fertilizer into the hole this is some
frozen daikon yeah there we go then you just put the
tree into the hole level with the there yeah
yeah replace any dirt that you moved and stomp all around it
to pack the dirt back in so it's nice and supported and upright
and that's it the job's done now in some places you can use this tube
looking thing to assist in your tree planting endeavors but here in bc the
tougher soil will jam them in an instant pretty much everyone we talked to said
to just stick with a shovel great advice if you're some kind of cave
we still think there's room for improvement for one using the shovel and
planting the tree it's not super ergonomic you're going to be bending
down constantly tiring yourself out who
needs that and two there's a key component missing
fun can you imagine how many people would sign up to plant trees if they did it
like this
everyone would sign up for tree planting if it was like this
let's talk about the improvements we've made to our tree planting cannon design
first we changed over from acetylene to compressed gas
while acetylene does pack quite a punch
it is well an extremely explosive gas and one
of our key design goals here is to not die if something goes wrong
our main inspiration came from bill chernoff who as far as we can tell owns
the world's only potato chain gun and he
was kind enough to give us some advice on how to make an air cannon like no
other although we would have liked to create a magazine for automatic firing like his
cannon it isn't necessary for us to shoot quite that fast and apparently his
mechanism took a lot of tuning and prototyping to get just right so we
decided for a simple breech style loading mechanism
here we go which should still be fast enough for us
to plant several trees per minute being able to reload quickly is no good
though if you don't have the muscle to back it up meet the muscle
this tank holds compressed nitrogen gas at 2 000 psi then our solenoid valve
right here controls the flow
here it is this mini tank right here
then another solenoid valve at the end opens up to fire
or as we call it make the fun happen
both of these solenoids are controlled by this simple electrical box right here
this little pressure release valve here will make sure that our pressure doesn't
get over 300 psi the limit of our solenoid valves and although by swapping
out a couple of components we could get much higher pressure i think you guys
are going to agree that it's got quite enough punch as it is are we armed right
now
i'm firing my laser baby three two
one wow
well that potato disintegrated
three two one go wow
let's plant some trees shall we
beautiful oh no i want to use the tube
i want to use the tube nope you have to line up the two okay
fine okay fire in the hole
give her one more
beautiful planted
the actual amount of digging was basically zero and we've embedded our
our bit of frozen zucchini here right next to the roots this thing is is
perfectly positioned for success right now
okay next round okay yep can i press the button this time sure can fire the hole
finger is numb okay
hold on let me just widen the white in the hole here a little bit
gorgeous ah ain't that a thing of beauty ladies
and gentlemen all right back it up
wait does the turning serve any purpose oh you were just having fun
okay all right so what all we got here is this uh potato potato beautiful a little
bit of frozen potato in there put that potato in there you're only at
like 90 psi right now you want to bring it around to like 250. oh
there you go fire in the hole
wow we definitely hit something that time
yep that was that was a root to only do like 90 psi or so this 90 or so okay
quick press armed and for the hole
okay so i think the stem actually did end up a little damaged that time
but uh okay let's try it let's try that again here let's go maybe six feet this
way i love that this one's bullet shaped
all right charging
whoa get a tree in there wow look at that
whoa this is so damn stupid let me just
loosen you up a little bit here you might have to shift just a bit you got
to use your sight there bud that's probably fine
that ain't gonna heal she ain't gonna make it past the winner
there we're still learning we're still ironing out the details let's uh let's
do another what if we leaned the whole thing down and we muzzle loaded it
so we put the pellet in from the end
and then we put the tree in from here
and then that way the pellet can kind of clear the path for the tree a little
maybe i'm not that far up listen to this guy all like well we did the
calculations and simulation and solid works
it actually kind of worked minus like the tree dying yeah the like the uh the
crater's about the right size so that actually brings us into something we had
wanted to discuss in this video um lockheed martin had the idea of carpet
bombing trees and youtube channel i did a thing actually made a great video
about rocket trees and we liked the idea but our concern
was that it was going to be pretty difficult even
with the proposed solution of creating like a
papier-mache or some kind of outer protective casing around each tree
because it's just a lot of force
also we didn't go that route because it would have been very time consuming to
create 400 paper mache bullets overall we don't
think that planting trees with a cannon actually makes a ton of sense especially
because there's so much stuff that you have to drag around with you but we
thought you guys might like some fun facts about our tree cannon uh it's got
an approximate barrel velocity of 140 meters per second or 460 feet per second
an ideal angle of launch of 36 degrees a distance without drag of over 1.5
kilometers a distance with drag of about 600 meters i mean all of that is
basically just a guess since it's hard to say how
stable the flight of our projectile would be and
how much you know a hypothetical tree could change the drag coefficient etc um
but we think it's safe to say that our projectile could go anywhere between 300
meters and one kilometer so this was clearly more
about having fun than it was about making a practical tree cannon but i
don't want that to distract from why this is so important in the amazon we've
managed to destroy about half of the mature rainforests and tropical
deforestation contributes a staggering 20 of world greenhouse gas emissions
deforestation also has a wide variety of unpleasant effects like the land heats
up faster without a forest soil without roots embedded in it erodes
faster dries up faster and contains less
nutrients for other plants oh and also
any animals that used to live in a forest that's gone
they're all dead now but the thing is we aren't planting trees in the amazon
we're up in canada so you might wonder what's the point of planting trees here
well half of the world's forest growth potential is actually found in just six
countries with canada being third on that list and when you're concerned
about things like air quality and climate change growing new forests is
incredibly important no matter where it is a mature forest is roughly carbon
neutral but as a new forest grows the
carbon is stored in the freeze providing a total reduction in the overall carbon
in the atmosphere worldwide that means that planting new forests in north
america and russia is a really great way
to combat climate change even if there are already plenty of forests there
so get out there have some fun plant some trees
and if you can or you don't feel like it that's fine
too just go to teamtrees.org to donate for every dollar that you guys
contribute Linus media group is going to match you up to ten thousand dollars
and since we have no way of tracking how much you guys contribute i guess we'll
just write the check today and go with the honor system here
speaking of honorable my transition to our sponsor for today's
video
knock knock hopefully it's not those guys
with the ring doorbell kit you can pre-screen anyone who's at your front
door because guys the year is not 1990 anymore and those peoples are so passe
the ring kit includes their video doorbell 2 spotlight cam battery and
solar security sign the video doorbell 2 has a motion sensor camera with
adjustable range it's got 1080p hd resolution and 160 degrees of vision it
features two-way audio so you can talk to whoever's at the door and it's
battery or 8 to 24 volt ac doorbell wiring powered the spotlight camera is
also 1080p hd also has two-way talk it's
got led lights and is battery or solar powered and it's got a siren the audio
is great because you can turn away unwelcome guests or you can tell them to
come right in if they're an unwelcome guest that you want to tell to come
right in like your in-laws you can instruct a delivery driver that you'll
be a second to get there before he runs away leaving a note and you got to get
your package tomorrow and you can just generally get peace of mind so check out
the ring kit it's compatible with iOS Android mac and Windows and you can get
it today at the link in the video description so hopefully you guys
enjoyed this video and you're motivated to go
get behind a really great cause
