I'm also really worried about teaching chemistry/physics in this day of hypervigilant anti-terrorism. I saw a family setting off model rockets on a mudflat in the Bay Area; a couple Karens standing next to us threatened to call the police on them. With the departure of LUNAR from Moffett because the Air Force didn't want them back, there are now no acceptable model rocketry clubs or sites in the Bay Area. And now you've got to worry that you'll end up on some FBI watch list for ordering basic chemistry sets for kids.
