Can you guess the riddle?

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

apparently Harvard grads couldn't solve it and kindergarten could solve it in a flash. can you? dont google!
