This is the easiest sensory activity, and I promise you more than likely have all of the supplies on hand! You can adapt this in so many ways, hide toys or letters in the foam, use it for color recognition, or just exploring new textures for younger tots! You can do this inside or outside, in sensory bins, bowls, or even using a highchair!
I follow Busy Toddler’s Recipe, but use my food processor instead of a hand mixer and add just a little touch more water.
1/4 cup tear-free bubble bath
1/2 cup water
Food coloring if desired
Whip together until stiff peaks form with a hand mixer or food processor!
