Straw Pan Pipes: a fun, at-home science experiment

Want to make a musical instrument that can play real notes? The pitch of a note is determined by wavelength, and the maximum wavelength that can be played depends on the length of the instrument. Make this simple set of pan pipes, then experiment with how you can get them to make different sounds!
The measurements for the straws can be found at www.ScienceOffCenter.org/science
