it would only work with helium in the box if you took all the air out and then added helium if you just added helium it would weigh more

I understand the consept of why this video was posted, but I'd just use a smaller box. It'd also be safer to ship the chopper in it's original packaging, than to tie it in a large glass box.

i'd just put bags of helium in it >_>. but to do that the money cost for bags and the helium might make it worhtless >_>

I'd just seal the box and suck the air out

the downward thrust it takes to lift a helicopter is equal to its weight to float, and even more to rise. thats the scale shows 10260 and 10270 at different times

its the displacement of the air inside of the box

its because the helicopter has to push more force down than its weight

Good one burningsponge. That downward thrust is definitely the variable. I was really stuck on this one.
