Pill (mint) cutting: Dollar Store trays, pill containers, and pill cutters make breath mints REALLY fun.
Sockets: Raiding Dad’s socket set keeps kids busy stacking, grading, and lacing.
Magnets: Is it magnetic or not? Who knew your junk drawer was full of such excitement. Just grab another handful of junk and the activity remakes itself.
Caribeaners : 4/$ at Walmart. Little kids will clip and unclip for ages. Just watch out, they’ll walk off with them and be clipping things together you never thought possible.
