    you can make a cloud chamber with clear plastic containers, a really cold frozen thing, high proof alcohol, and hot water (example)

    these can visualize cosmic radiation, or you can always hold a smoke detector next to it to see it really pop off

    so you can literally have an inexpensive hobby involving nuclear physics haha

      I like to imagine radiologic security checks are done by border agents with cloud chambers. Not fancy electronic detectors, just literal cloud chambers. Just imagine there’s some customs guy at a port in LA. He’s standing outside a shipping container. In his hands he has a giant glass dome filled with fog. And he’s just awkwardly waving this giant impractical object all over the surface of a shipping container.
