today on REBRICKULOUS we're dropping eggs from four stories up do you think our
Lego builds can stop these eggs from getting scrambled? three, two, one, drop it! no way no way no way
what's up guys so today we are gonna be doing an egg drop which we've done
before but this time we're gonna be doing it with a little bit of help from
a real-life physicist dr. Rob Coyne Rob hello there hey
alright so Rob can you tell us what we need to do to make sure that our eggs
survive this fall I'd be happy to you see you got a whole bunch of things that
you're fighting against when you're doing an egg drop when you start up real
high you got a lot of energy and you got to
dissipate that somewhere hopefully not into the egg step one
reduce the total amount of energy that dropped down number two when the egg
hits and it's gonna hit you want it to not hit directly so redirect that impact
make it go around the egg and number three and we want to spread that impact
out the longer that impact takes the better chance your egg has is surviving
the drop I think all three of us are gonna have to find out some way to make
this work there's gonna be a competition this time oh this time we're going head
to head the head we have three hours we have three eggs it's gonna be four
stories off the ground that's 40 feet may the best egg win
all right eyedroppers you ready yeah ready okay and you have three hours
starting now I think the plan is to work from the inside out because the inside
is gonna be where the egg is so I'm gonna use these pieces here they're little bit
more flexible it's actually cradle my egg oh it's safe right I am thinking
that my build is going to be kind of a spiky like a sea urchin because that way
when it falls it'll capture the impact I'm gonna be making something that's
like more of a cage and I'm hoping that I can make a cage inside of a cage
all right we're at our halfway point I hope your creations are starting to take
shape okay kicking it into overdrive
one minute left okay who I was supposed to put many more tires on this but I
have no time for this. three hours went by like that. so this is my build on the
outside of the build that use tires to kind of absorb the impact when it hits
the ground it's not enough sorry so because as you can tell I had plenty
more in store but that's okay I got my cages out of a cage concept going use
these flexible Technic pieces to hold it in place my egg pilot today is gonna be
this hard boiled character yoko and inside his cage he's cradled by two
rubber tires that keep him safe my sea urchin has evolved from the water and is
now going to be flying high in the sky and will delicately land like a cloud my
egg pilot today is Oswald Junior you might remember his father from our
first egg drop episode Oswald Junior will be riding safely in
this cockpit while these long outside pieces will hopefully spread the force
of the impact. home sweet home it's gonna be safe so as you can see I built a
house for my egg because I'm all about comfort doesn't look very safe right
wrong outside I'm attaching this parachute which will help to slow the
descent this is my egg pilot mark looks a little creepy but you're gonna like
him once you get to know him. now that this builds are done let's go outside
and see who survives
all right D's going up first and I'm not scared at all at the same time this
is really really high we're 40 feet in the air
you can drop a pillow from this height in it with shatter I'm gonna be dropping
this though there's gonna be our control just to see exactly what happened if
there was no production around an egg we're gonna let this splatter we're
gonna see that in slow motion yo cut me down let's hope your builds do a little
better than that all right down
they're going first aid. unfortunately it looks like it wasn't quite strong
enough to keep the egg in its nice cushioned interior and it popped out
just at the end but as you can see the egg is still largely intact in fact
there's still yolk in there we had a little bit more interconnected on that
interior basket I think it would have made it that oh here we go folks been
nice knowing ya it's it's pretty good it's a little windy hey safety guy can
we go just a little bit higher I think it'll help the parachute, oh he's daring, here
we go all right that's good are you guys you can stop no stop that's good that's
good tell me down three two one
oh no way no way no way
oh but it's just that I think it did I think it did it close to the target
know what no one can look away is it alive
unbelievable so this right here goes to show why slowing it down is so effective
you take all of that potential energy that was up here and instead of slamming
it down into the egg you slowly float down and you reduce the amount of energy
you have to dissipate and so mark survived
Christiana was a little nervous to get up in the basket so she came up with a
pretty amazing plan B, she actually hooked her build into a drone the drone is
flying over the target right now don't kill us
are you ready C? Are you in your position?
-..... oh hey I know what's up it is hey it's alright it's okay okay I'm here we have
a new friend now and he's gonna have a lot of fun today because I know he's
gonna survive survive.... Alright so this started off as a really good idea
unfortunately I think these just weren't quite rigid enough so when it hit
instead of redirecting the impact like we expected it to it just kind of bowed
and brought the egg right down to the ground as you can see what's at least
it's trying to get back to the bullseye but if we talk about target practice
Tyler definitely did not get anywhere near it
that was not the objective the objective was a safe and happy egg and I
accomplished that objective did you we learned a ton this was really cool we
yeah we salute you and we salute science science science like one of these two
