All you need is 5 cups of regular flour and 1 cup of baby oil. Simply mix the two together and it turns into this silky soft sand. You can throw some sand toys into your tray or you can use items such as spoons and measuring cups
Cool the kids off with a homemade sprinkler. Take a 2 liter soda bottle, poke holes in it. Attach to a garden hose via a male to male adapter that cost less than $5 at Lowes. Toss over a tree branch and let hang. You can adjust how the water sprinkles by adjusting the water flow. When the bottle gets beat up, just replace it, no additional cost!
