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.
What am I?

I Am Pressure
