One of the more mischievous kids in my third grade class was the son of the high school chem teacher. He purchased a chemistry set at the book fair that year. He and another kid took it into the bathroom by the cafeteria and drank a few "experiments" from the kit in the box. They both got violently sick and an ambulance came. I'm really glad I stuck with my Box Car Children collection and Calvin and Hobbes book mark that year.
Yup. Ours had some really expensive hobby items in addition to the books and book accessories. They had a rock tumbler kit one year I remember wanting really bad. My grandparents ended up getting me one for Christmas. I recall a telescope one year as well.
That snuck up on us and we sent our 1st grader in with a $100 bill and a note saying to only let him spend $20. The neighbor 1st grader asked us if we are rich after that...
