Doodle Dee Dum
I used a metal can, elastic bands and packing tape to make my musical instrument.

I cut the elastic bands and stretched them across the top of the can and taped them in place and decorated the can.

I can change the pitch by tightening the elastic bands.

I can also change the pitch by filling the can with water.

When I pull the elastics even tighter, the sound my musical instrument makes is louder.
