Beans. Pretty self explanatory. We put in 5 or 6 types of beans and some other fun things like an egg carton and scoops, cups, spoons, etc. The girls found all sorts of creative things to do with the beans. I thought they'd like sorting the different kinds but they weren't really interested in that. Beans were definitely a hit though.
Interested in other sensory tub activities? We've used straws, packing peanuts, suds n' TP, rice, screw on caps, and mashed potatoes.
