We spent a fortune on "moon dough" at Christmas for Tara and was pretty disappointed so when i saw a recipe of moon SAND i thought maybe this will work better so we gave it a go!
Moon sand recipe is
6 cups of sand mixed with 3 cups of cornflour then add 1 and 1/2 cups of water slowly until you get a consistency that is manageable. We added blue colouring to the water as well.
Moon sand is basically soft like sand but wet enough to mould and stay. Great for mud pies and sandcastles!
