Zero waste and completely environmentally friendly sensory play. This activity is a go to for my son and really meets so many sensory needs.
Anytime you cook with eggs don’t throw the shells out. Wash them with some water, pop them in the oven or air fryer for about 5 mins or so, then take them out and store them in a glass jar.
You now have a really accessible (this is important) material that you were going to throw out anyway. Once the shells are crushed and don’t with you can keep them aside to use later as a fertiliser..more on that another time.
When I said accessible is important I meant it. As a parent/teacher/caregiver you should always have things easily on hand when needed.

Also how beautiful do those crushed shells look in the last picture 😍
