* a riddle *

I turn polar bears white
And I will make Du cry.
I make guys have to pee
And girls comb their hair.
I make Berühmtheiten look stupid
And normal people look like celebrities.
I turn pfannkuchen brown
And make your champagne bubble.
If Du squeeze me, I'll pop.
If Du look at me, you'll pop.
Can Du answer this riddle?
