Folding Paper Math

Just a light math post today that amazes me every time. Hope you use it in class!

Imagine a large piece of paper in front of you. If it were possible, (rumor has it that it is only possible to fold a piece of paper 7 times) fold it in half a 100 times. How high would the resulting wad of folded paper be?

Here's a hint.

I decided I would be a bit of a pain and not give the answer until someone asked me. Do the math yourself or leave a comment and I will give the answer!
