We used to call this “permanent chalk” when we were kids. But we did it in reverse - we’d hose down the driveway and then draw on it. Made our intricate bike obstacle courses last weeks during Michigan summers.

We discovered this accidentally by leaving a chalk bucket out in the rain and now it's the only way my daughter wants to chalk. I agree that it's 200% more satisfying tho!

Sidewalk chalk is great n all but have you ever pre-soaked them so they turn into creamy pastels instead? Really eliminates the scratchiness that might give some folks the sensory ick. This is my preferred way to chalk!
