take it out nothing it's a balloon with a hole in it and all the years go well I'd say the air is still blue so where's the air that's water if that water it'd be frozen solid that's liquid air what when we place the balloon in the liquid nitrogen the air inside the balloon gets

really cold when particles of a gas get

cold they start to slow down and take up

less space if we can get the gas cold

enough we can change it from a gas to

liquid that's what happened inside the

balloon we changed all the particles of

nitrogen and oxygen to a liquid so how

do I get my balloon back we just have to

place it someplace hot like the table

oh so I get now the reverse is happening

the heat in the table is making the

liquid air inside boys when a liquid

boils and changes to a gas the part will

be faster when the car will move faster

they take up more space and the balloon

is big
