WHAT YOU NEED: a record player, a record and a £5 note.

STEP 1 - SPIN RECORD: Start the turntable spinning, but don't put the needle on the record.

STEP 2 - CORNER IN GROOVE: Instead place the corner of the £5 note in one of the spinning record's grooves.

STEP 3 - CURVE THE NOTE: Curve the note a little to get more volume.

STEP 4 - LISTEN TO SOUND: You should be able to hear the music on the record playing. The £5 note turns the vibrations from the bumps in the record groove directly into sound waves in the air.

TIP: Under a microscope you can see the groove is actually V-shaped. Usually one side of the V vibrates your left headphone while the other side vibrates the right, to give a stereo sound. Curving the £5 note points it more towards one of the sides.
