Ecology kits, 1973 This Mr. Wizard kit, as its name implies, consists entirely of culturing molds and bacteria. That should be done only under professional supervision--even if you don't follow the kit's suggestion that you culture matter from dirty garbage cans. We rate it Not Acceptable.
Candy pellets, 1973 For a nickel, a kid who buys Orbits with Blower gets a packet of tiny, hard candy pellets and a fairly large-bore plastic straw. It's dangerous to other kids when used like a pea shooter--and dangerous to a kid who might easily inhale the pellets.
Carpet sweepers, 1959 Most are relatively easy to empty: Spread newspapers on the floor, tip up the sweeper with one hand, and reach down with the other hand to pull on a metal tab. Empty the sweeper each time before you store it, we add, or whenever it gets too full.
