When I was a little girl, I loved getting "Things of Science" kits in the mail. These kits came in little blue cardboard boxes, and I usually received one each month.
In some cases, you would need to provide supplies that most households had. To perform all of the experiments in this kit, you would need to have two flashlights with D-cell batteries, and some glassware and vinegar.
However, the special supplies were provided. This kit on electricity even contained a tiny compass!
