Oh gee, this thread has progressed, I could say, almost alarmingly, since I last visited. In some way I suppose, its good to know that we still have access to chemicals, but in view of the world's current situation, one must surely shake in ones boots!
Marty, its interesting your change from chemistry to electronics. I did toss up between those two professions back in 50s but opted for the chemistry. I felt that chemistry was the way to go and electronics just made a good hobby - which it did/still does. Still got my amateur radio gear. But there was definitely a change in social development when computers arrived on the scene in the late 70s, and that I feel is when electronics really took off.
Mark, Lovely to see some basic chemistry - complete with the old but vital safety precautions i.e. always add the acid to the water so if it spits you will be sprayed with water plus a little acid rather than the reverse; and of course wearing the safety gear.
Kerrie, if you want a good read about what kids can get up to when left to themselves, try "Lord of the Flies" by William Golding.
Think I've now caught up.
