bang I’m ready to launch this coin into

bang I’m ready to launch this coin into the air like lunar modules in space

the air like lunar modules in space

the air like lunar modules in space here’s the problem I’m not really sure

here’s the problem I’m not really sure

here’s the problem I’m not really sure about what’s involved in flipping a coin

about what’s involved in flipping a coin

about what’s involved in flipping a coin in terms of physics so what we did was

in terms of physics so what we did was

in terms of physics so what we did was we hired a guy who actually builds

we hired a guy who actually builds

we hired a guy who actually builds catapults he’s an expert in getting

catapults he’s an expert in getting

catapults he’s an expert in getting things airborne his name is Jeff we

things airborne his name is Jeff we

things airborne his name is Jeff we asked Jeff to build us a huge mechanical

asked Jeff to build us a huge mechanical

asked Jeff to build us a huge mechanical thumb so that we could analyze the

thumb so that we could analyze the

thumb so that we could analyze the physics of a coin flipping through the

physics of a coin flipping through the

physics of a coin flipping through the air on a massive scale I was fully

air on a massive scale I was fully

air on a massive scale I was fully expecting this massive coin to like

expecting this massive coin to like

expecting this massive coin to like knock a tree branch off the top of a

knock a tree branch off the top of a

knock a tree branch off the top of a tree on the top of a mountain where

tree on the top of a mountain where

tree on the top of a mountain where little goat lives in that little Hut

little goat lives in that little Hut

little goat lives in that little Hut I know what I’m trying to determine but

I know what I’m trying to determine but

I know what I’m trying to determine but what are you trying to determine what

what are you trying to determine what

what are you trying to determine what I’m probably determined is will it not

I’m probably determined is will it not

I’m probably determined is will it not destroy itself well you’ve said a pretty

destroy itself well you’ve said a pretty

destroy itself well you’ve said a pretty low bar for success and you see that we

low bar for success and you see that we

low bar for success and you see that we have our head side and our tail side

have our head side and our tail side

have our head side and our tail side right this is the first time I’ve shot

right this is the first time I’ve shot

right this is the first time I’ve shot this with a coin on it so so you’ve

this with a coin on it so so you’ve

this with a coin on it so so you’ve never actually tested our mechanical

never actually tested our mechanical

never actually tested our mechanical thumb and finger before testing it by

thumb and finger before testing it by

thumb and finger before testing it by itself so basically this is a television

itself so basically this is a television

itself so basically this is a television event right it’s the first time for it

event right it’s the first time for it

event right it’s the first time for it I’m gonna stand with you okay okay clear

I’m gonna stand with you okay okay clear

I’m gonna stand with you okay okay clear firing well it didn’t break

firing well it didn’t break

firing well it didn’t break I’m gonna model what just happened we

I’m gonna model what just happened we

I’m gonna model what just happened we set our coin on our index finger we put

set our coin on our index finger we put

set our coin on our index finger we put our thumb in position and then we

our thumb in position and then we

our thumb in position and then we released the potential energy and our

released the potential energy and our

released the potential energy and our thumb robots what I need is a crowbar

now it moved we’re getting better things

now it moved we’re getting better things are a bit heavier I’m gonna go get the

are a bit heavier I’m gonna go get the

are a bit heavier I’m gonna go get the sawzall

go get another wheel I should have

go get another wheel I should have thought of that one I got it don’t worry

thought of that one I got it don’t worry

thought of that one I got it don’t worry about it it’s fine you think Jeff even

about it it’s fine you think Jeff even

about it it’s fine you think Jeff even knows he’s on TV

knows he’s on TV

knows he’s on TV firing no know what we’ve got a full

firing no know what we’ve got a full

firing no know what we’ve got a full rotation went through the air landed

rotation went through the air landed

rotation went through the air landed heads up the first rule of mechanical

heads up the first rule of mechanical

heads up the first rule of mechanical thumb club is don’t make your mechanical

thumb club is don’t make your mechanical

thumb club is don’t make your mechanical thumb so huge and heavy that it can’t

thumb so huge and heavy that it can’t

thumb so huge and heavy that it can’t create enough kinetic energy to launch

create enough kinetic energy to launch

create enough kinetic energy to launch the coin into the air eventually we

the coin into the air eventually we

the coin into the air eventually we decided to try a slightly smaller coin

decided to try a slightly smaller coin

decided to try a slightly smaller coin got it now this should go sailing

huh tell me one go right ahead

huh tell me one go right ahead okay I thought you were no here we go

okay I thought you were no here we go

okay I thought you were no here we go all right

hey Doc ladies and gentlemen we thought

hey Doc ladies and gentlemen we thought this coin was gonna sail through the sky

this coin was gonna sail through the sky

this coin was gonna sail through the sky and just because like killing geese

and just because like killing geese

and just because like killing geese messing up satellites in space but I

messing up satellites in space but I

messing up satellites in space but I feel like we did learn some valuable

feel like we did learn some valuable

feel like we did learn some valuable lessons needs more potential energy and

lessons needs more potential energy and

lessons needs more potential energy and your thumb should weigh less than 600

your thumb should weigh less than 600

your thumb should weigh less than 600 pounds so that you have enough energy to

pounds so that you have enough energy to

pounds so that you have enough energy to make it flip right yeah something like

make it flip right yeah something like

make it flip right yeah something like that
