8 cups of flour

1 cup of baby oil

Combine the flour and baby oil in a large tray or container. I used a large bowl, but I would recommend something with a lid if you plan on storing it and reusing it.

The sand is really soft as you would imagine, and it packs really well so you can still make sandcastles with it.
How it worked for me:

My kids loved it! They begged me to make them an entire sandbox full. They played with this stuff for hours and hours. Well worth it! They built all kinds of things with it. Had no problems building, it held together pretty good.
