Modern Chemistry (Sets)

My neighbor is planning to buy a chemistry set for her son (second grade) and she asked me for some suggestions. It was a chemistry set that I received back in second or third grade many years ago that sent me down the path to a career in chemistry, so I thought I’d spend a little time trying to find a good one. I’ve talked about this before, but they just don’t make chemistry sets the way they used to. Perhaps for safety reasons, perhaps for environmental reasons, perhaps for liability concerns – there just are not that many chemicals in chemistry sets any more. And that’s a real shame.

My chemistry set (Chemcraft) had plenty of chemicals in it, and there were plenty more you could order. These days, you are lucky to find ten chemicals in a set, sometimes as few as two or three. I did find a Thames and Kosmos set which contained 20 different chemicals, but many of them were boring and the set cost about $250! I finally suggested a less expensive version of the Thames and Kosmos set to my neighbor. Of all the sets I checked out, it appeared to be the best one. The deciding factor was the inclusion of potassium permanganate. Even my old chem. set didn’t have that one. How did permanganate slip through the safety police?
