Yup - and I remember making rocket fuel in our high school chemistry class and launching the rockets afterward from a vacant lot nearby, with an occasional mislaunch where the rocket blew up just after launch or worse, tipped over and headed for somebody’s house.
I remember the rockets in HS, too. Usually they were set off near the football field.
