YOU NEED:

• A ten rupee note
• Two paper clips
• Two thin rubber bends

This is a common trick with ten rupee note folded as shown and with two paper clips on it.

If you pull the bill apart holding the ends until it is flat, the two clips jump on the bill.

Put two thin elastic bands around the note, inside each fold as in the illustration. Now pull the ten rupee note flat. You will be taken aback by what happens!

What happens is a chain, with clips in the middle and a rubber band at either end.

HOW DOES IT WORK?

You need to pull the bill ever so slowly at the ends to find out how it works. The clips and the rubber bands are positioned such that they interlink to create the chain.
