Check out these Washy Squashy soaps. Colourful, non-toxic, oil-based, eco-friendly soaps that mold into shapes! I’m actually considering getting these for my mother-in-law who loves to sculpt (she is super creative and would get a kick out of these).
I’ve also been on the search for a bubble wand for the baby shampoo I use, so that we can blow bubbles in the bath. Here’s what I’ve found so far…but I’d like to find a non-plastic solution. I’ll keep hunting and if you know of one, please share.
