This is a very interesting trick that you can do with paper.
Cut out three paper strips from a newspaper, using the entire length. Make them about one inch wide.
Paste one strip together as shown in sketch No. 1 without making a twist in the paper.
Then paste the second as shown in sketch No. 2, making a half-twist.
Before you stick the third ring together, give the paper two half-twists as in No. 3.
Cut each ring through the center as shown in pictures 1, 2 and 3.
Your friends will be greatly surprised that you'll make one large ring, two small ones and have two linked together.
Pictures No. 4, 5 and 6 show what you will get after cutting the three original rings in half.
