Short Top Hat(Hat Guy's Hat)

It's like a top hat but shorter.
It's Hat Guy's hat from the web comic XKCD

Materials:
Box Cutter
Cardboard
Duct Tape

First of all you have to cut a circle. The size that the top of the hat should be.
Then cut another circle that is a few inches bigger than the first.

In the bigger circle you should cut a head hole. Not enough to go over your head but just rest on top of it.

Create a small strip of cardboard that is the length of the circumference of the small circle. and the tallness that you want the hat to be.

Use duct tape to connect it all together.
