Musical Cake tins

It easy to make and tune a simple stringed instrument- and write your own music to play on it.
You will need:

• a square or rectangular metal cake tin
• 5 rubber bands that will stretch lengthwise around the cake tin
• A piece of thick cardboard, big enough to overlap one end of the cake tin
• 5 soft drink caps or small pebbles.

The thing that we did was:

1. we made it then we tested it by flicking the strings then we made sounds with it.
2. Then we tried to make a song

It was really cool and fun to learn all of it and I learnt a lot of new things.
