I miss the old chemistry sets. Yes, you could easily injure yourself or others, but … The sets were bought and sold with the understanding that the person using them would have at least a smidgen of common sense. Despite many, many sessions with my set, I never once burned myself, spilled acid, set the house or neighborhood on fire, poisoned anyone, etc. It helped fuel my ongoing fascination with all things scientific, however. I fear that there’s now an entire generation of kids who will not go into chemistry or science because of fears of turning out chemistry hoodlums.
