Balloon in liquid nitrogen
Yeah, we know what it looks like, but it's just a science experiment.

this would be good if the quality wasnt so bad and if every hadnt done the same thing in primary school

#2 How can you know that this is done in primary school? You obviously failed any school you ever attended..

Placing a ballon in extreme cold causes the rapid contraction of the contained gas as it cools. ItsSimple.

Ouch #2 that must of hurt! Anyways, nice going #3.
Video's pretty awesome, anybody why the balloon re-inflates? It reacts as if there was a pressure difference but that can't be in that case...
An explanation would be great!

#5 The rapid return from sub-zero to room temperature causes the air inside the balloon to heat, thus returning to its original state. What is amazing is that the rapid cooling does not rupture the balloon, as thermoplastics are generally brittle at cold temperatures.

#6 i believe that the reason why the balloon was not ruptured is because it could be made of latex rubber (he he) which was probably cured using vulcanization (although not sure) which both strengthens and hardens the molecular bonds, forming cross links between the polymer chains. this allows the rubber to become deformed under stress, while enabling the rubber to return to its original shape once the stress is released.
...but i could be wrong,

I don't know about you guys, but whatever that noise was in the background (sounded like running water) it made me wanna go "P"
I say, science is fun!! but only one monkey head 
due to poor quality, otherwise it was cool

#7 i thought vulcanization is the process of hardening rubber so is the balloon rubber hardened or i misunderstood your statement.

Jesus Fckn' Christ! I wanna make this experiment with my dick inside a condom!

#9 the point of vulcanization is to make the rubber stronger so that it can withstand stress without breakage, otherwise, it may rupture when it is blown up. it is likely that the balloon was able to withstand such harsh temperature changes without breakage because of vulcanization, but personally it was only a guess. you know there is such a thing as google or wikipedia, perhaps you should try it some time.

This is a simply explained experiment, but still cool to watch, nonetheless.
