Same can be said for a lot of other things/activities many of us enjoyed during childhood.
E.g. I remember playing with real chemistry sets with chemicals that could be potentially harmful if ingested, alcohol burners, glass tubing we had to flame-polish ourselves. Those are long gone; just replaced with "safe" but incredibly dumbed-down kits that are little more than dyes/food-coloring.

The pool supply section has 10 molar hydrochloric acid. The garden section has sulfur. The paint section has xylene, acetone, and methanol. For example, you can purify garden sulfur by recrystallizing it with xylene. This is plenty dangerous, since xylene is almost like gasoline (a bit less volatile) and you'll be heating it up nearly to boiling. The aromatic ring structure is required; most other solvents produce deadly hydrogen sulfide gas.
