Car with helium balloons on it on Barkers Pool: Brainiac question!


Recommended Posts

I've just walked past a car covered in helium balloons on Barkers Pool (charity awareness fundraising thingy).

 

It got me wondering, in a Brainiac kind of way, how many helium balloons it would take to lift a car from the ground and let it float away.

 

Any scientists out there want to hazzard a guess?

Its funny you should say that, because i saw a lad on fargate yesterday with a brainiac t-shirt on, i thought it was in town somewhere at first.

Unltil i realised its something he's bought from one of the mad shops on or around division street.

Going by this website http://science.howstuffworks.com/helium2.htm

it says a 1 foot diameter baloon volume 0.5 cubic m, has a lifting capacity of 14 g.

That would mean to lift 1 kg you would need 71.428571.

(1000g/14g (lift for balloon))

 

therefore to lift one ton you would need 71428.571 balloons or 71429 rounding up.

So depends on the weight of the car now!

And would that just lift it a little bit, or would it float away?

 

 

The lift of a helium balloon depends on the density of the atmospeher around it, so it would only lift so high anyway as with just a single helium balloon.

people,people,people

 

please stop this before it becomes any bigger and starts to invade you rlife. its onlt a siple question at the minute but what if it manifests itself into actual experiments.

you wont be able to look at anything without wondering and guestimating the number of ballons it would take to lift it!!!

 

 

hmmmm i wonder how muc h that toast weighs. how many ballons would that be. its a high air pressuse day today so iwould have to equate that into my estimations

 

etc

 

please stop before you get hurt
