You can amaze your friends with this piece of paper that has only one side! Here's how to do it:

1. Cut a long, skinny strip of paper.

2. Make a loop with the paper by matching up the narrow ends.

3. Make one twist into the paper and tape the ends together.

4. With your marker, start drawing a line on the piece of tape and continue the line without lifting your marker until you meet up at the tape where you started.

You drew a line on both sides of the strip of paper without lifting your marker. The paper only has one side!
