Coffee Can Experiments

Back in November, the girls did a coffee can experiment
(from the book Coffee Can Science).

They learned how sound vibrates on the string and echoes into the can. (Nylon cord worked better than cotton cord due to the cotton cord being softer and absorbing the vibrations.)

Mina has a written a mystery book and is typing it up on the computer (and she has another one already in the drafting phase).
