I actuall had a gun safety course in 8th grade. My 7 yo son had to take small countable item to school in a plastic bottle for science. No problem We had 10k air soft "bb's" small round plastic pellets like beads. We counted out a couple hundred or so and put them in the bottle for estimation.
My son when asked about the beads replied they were bb's the teacher took them a went to officewhere I was called to come get them. Plastic beads people. Stupid political correctness
