I need answers to this riddle!!?

Okay my cousin sent me this riddle. 83% of Kindergarten children got this right, 3% of Havard students did:

I turn polar bears white, and I make you cry, I make guys have to pee, and girls comb their hair, I make celebrities look stupid, and make normal people look like celebrities, I turn pancakes brown and make champagne bubble, if you squeeze me I'll pop, if you look at me you'll pop.

So far we've come up with Oxygen or water, but I'm not sure. Any suggestions?

Maybe paparazzi? They make you cry, make you pee pants, celeberties look stupid. Look at them and they will pop their cameras.

Hmmm... I've seen a question like this before. (one with kindergarteners and harvard students) and the answer to that one was nothing, seriously! so I say, nothing.
