Hands-on Plastic Kits are about $20. You don’t need a kit. The background and lessons are free. One of the first lessons is a plastic scavenger hunt. Gather as many types of plastic as possible. Cut small pieces of different plastics to use to test. Be sure to label the type of plastic. The density lab requires 70% isopropyl alcohol (rubbing alcohol) and calcium chloride, Driveway Heat. HST sells CaCl2 for $3.75 if you live in a warm state. The hands-on plastics labs are School not fun. They work well for kids 10-14. Hope you find this useful
