Science Projects And Inventions

YOU NEED:

• A magnet
• A low table with a thin top
• A sheet of whitepaper
• A metal paper clip
• A compass (optional)

Again secrecy is the bottom line here. Take a magnet and tape it to the top of your knee where it remains

concealed. Select a table with a thin top.

The table should be low so that the knee with the magnet taped on it can touch its underside.

Take a sheet of white paper and put in on the table top. Now place a metal paper clip on the paper just

Above your knee with the magnet stuck to it. The clip will move on the sheet of paper if you move the knee

under the table.  A compass needle can be moved in a similar manner. Place a compass on the table and move  your

knee with the magnet. The compass needle will begin to swing given the magnetic force.

HOW DOES IT WORK?

The magnetic force moves the pin and the compass.
