when balloons go up in e air...
-
where do they come down??? so if a lot of ppl release a lot of balloons up in e air, wont there be a lot of rubber falling down from e sky? but i like never see before lea..u guys noe or not ar?
-
it goes up, expands due to pressure, blows up once the balloon cannot handle the stretch.. and somewhere, there are rubber bits falling to earth
-
i thought ballons are pumped with hydrogen(correct me if i am wrong) but the gas will leak out and soon the ballon will come down
-
hydrogen is dangerous.. it's helium...
and no.. they rise and the balloon expands due to the drop in pressure up there..
P1V1 = P2V2
P1 = sea-level pressure
P2 = pressure as it floats up..
as it goes up, the pressure decreases therefore P2 drops.. V2 must increase as P1V1 is a constant...
as V2 keeps increasing, there is a limit to the stretch of the balloon.. once the limit is breached, the balloon explodes...Originally posted by StarPuppy:i thought ballons are pumped with hydrogen(correct me if i am wrong) but the gas will leak out and soon the ballon will come down -
Who the heck pumps hydrogen to balloons?

Helium!
only puppy pump hydrogen into balloons!
ROFL! -

hmm..i think maybe carcar tyres needs to be filled with hydrogen....Originally posted by toyota-corolla:

WAHAHAHA!Originally posted by ndmmxiaomayi:lol
LAUGH LOUDLY!! -
how long does the effect last? is helium toxic?Originally posted by Stootpid:i inhaled helium gas before. my voice become so high pitch
i've known bout this but dun have the courage to try it leh -
I've tried it countless times.. it lasts for a very short time only. But it can be dangerousOriginally posted by stookie:how long does the effect last? is helium toxic?
