Make Paper Cup Helicopters!

I've always wanted to make something that would fly. I had some...not some, A LOT of paper cups. So I thought just make something with them? So here's my idea:

Here's what you will need:
A paper cup
scissors
a fan
hands
paper(optional)

draw on the paper,
wrap the paper around the cup so the drawing is facing out,
cut the extra paper off, Glue to cup.

cut to the bottom of the cup once. about 2 centimeters over, do it again. repeat till you get back were you started.

fold them down so it looks like a sun.

put fan face up on the floor. turn it on. put your finished product over the fan. YAY it sours!
