Things of Science #333 - Sound.13This Things of Science unit came with a few small inexpensive noise-makers (small bell, whistle, etc.) and a few things for making simple instruments (rubber band, plastic tube). This is a unit where perhaps the booklet is a good deal better than the things.

Another eBay purchase that came only with the booklet. I think though someone interested in recreating this unit could improve upon the “things” that originally came with it anyway (no doubt size constraints — having to ship the things in the mail — limited what the Things of Science could provide).

Enjoy the booklet:
