Edward loves to play with this and it’s so easy to make. We use 200g Flour and Baby Oil. No actual measurement for the oil as we just pour and pour until we get the texture that we like. Typically, when you can mold it. And after you crush it, it will return to sand like.
Although Edward likes it, it’s very messy that we have to take a bath right after. Still, he enjoys it so we just let him.
