What Makes Polar Bears White

Q: 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. Can you guess the riddle?

A: I dont know, help me figure it out :-)
