Hi

Is this some sort of a special effect or can you really do this?

 

 

Also how do they do the voices? I get helium but what about the other thing?

John

it`s Sulpher hexafluoride gas, it`s VERY dense!

 

and it`s no Trick and certainly NOT "majik"

technically its physics. the chemistry would come in the making of the Sulphur Hexafluoride.

well . i would ask about making Sulphur hexafluoride gas

 

it would be fun to show children something totally different. and educational for me

Problem is to get it out of your lungs again

Stand on your head!

I think it's a stupid thing to make those kids breathe it in, no matter how less dangerous it is! It a bad habit, especially to teach it to children.

 

One of the basic rules of lab says: Never inhale directly anything!

Well i am not going to let people inhale it. but floating boat is actually rather fun thing.
