Here’s how to make a fun & simple wind instrument from a soda bottle –

The plastic bottle, this common object of consumption, this vulgar domestic waste, can replace the noble bamboo to ape a wind organ. It only takes, with a pair of scissors, to carve a longitudinal “whistling” slit within the body of the bottle. Several sizes of slit are possible. The sound is not as pure (more or less muffled depending on types of slits) as it is with the sound of bamboo. On the other hand, the time taken to carve the slits in plastic is negligible compared to carving bamboo, moreover, the cost of the material is absurdly low.
