Got the idea from Tinkerlab. Cloud dough kept my kids busy for a couple of hours which is pretty huge for them. The dough feels light like flour but compacts well like wet sand.

It was really easy to make. Use an 8:1 ratio of flour to oil. I used all purpose flour and baby oil. Since I knew both my kids would want to play I used 12 cups of flour with 1.5 cups of baby oil. Made the mixture in a large but shallow rubbermaid tub. Just mix with hands for about 30 seconds. Threw in some silicon muffin cups(regular and mini size), a couple plastic cups, and a small hand shovel.

For now I just put the lid on to save it for another day. The area did get a bit messy since my kids can not be trusted to keep messes contained. It was nothing that a quick vacuum couldn't cure.
