The World's Hardest Riddle

Ok, I got this off online from someone else so this isn't mine but here it is:

" 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?"

97% of Harvard graduates can not figure this riddle out,
But 84% of kindergarten students were able to figure this out,
In 6 minutes or less.
