Ingredients For Homemade Moon Sand

All-purpose flour – This is the base that gives moon sand its soft, moldable texture. You can use whole wheat flour, but the color will be darker and you may need to add a little extra oil. Heat treat to 165 degrees Fahrenheit before use.
Vegetable oil – This binds the flour so the sand clumps and holds shape. Canola oil or sunflower oil work just as well. For older kids, baby oil can be used for a silkier feel (not taste-safe).
Gel food coloring – Adds fun color without adding extra liquid. Liquid food coloring can be used, but the sand may be softer.

How To Make Moon Sand

Spread 8 cups of all-purpose flour on a parchment-lined baking sheet. Bake for 5 to 7 minutes, stir once halfway through, and check that the flour reaches at least 165 degrees Fahrenheit. You can also use a microwave to heat treat. Place flour in a large microwave-safe bowl and heat in 30-second bursts, stirring between each round, until the flour reaches 165 degrees Fahrenheit. Allow flour to cool completely.
Place the treated, cooled flour in a large mixing bowl or tub. In a separate container, stir the gel food coloring into the vegetable oil until the ingredients are fully blended. If you plan to use more than one color, divide the oil evenly before adding the different food colorings.
If you’re making more than one color, scoop the flour into separate bowls first. Drizzle the colored vegetable oil over the flour. Use your hands to mix it in, squeezing and rubbing until the flour feels like soft, damp sand that can hold its shape when you press it together.
If the moon sand feels too dry, add a splash more oil and remix it. If the consistency is too wet, sprinkle in a little more flour.
Transfer your moon sand to a shallow bin or tray. Kids can mold it into fun shapes, scoop it, or use cookie cutters to make fun designs.

Storage

Store moon sand in an airtight container or a sealed plastic bag at room temperature. It should last up to two weeks.

If it starts to dry out, knead in a teaspoon or two of vegetable oil until the texture feels right again. If the moon sand smells funny, changes color, or gets damp from play, toss it and make a fresh batch. It is quick enough to whip up again.

Pro Tips

I always heat treat the flour first, heating it to at least 165 degrees Fahrenheit. It is a simple step, but knowing the base of the moon sand is safer for little hands that might wander toward their mouths makes me feel better.
To cool flour quickly, transfer it to a fresh baking sheet or a big shallow bowl. This cools it down in about 10 minutes instead of waiting half an hour.
Mix the gel food coloring into the oil before it ever touches the flour. This way, the color blends in more evenly, and you do not end up with streaks.
If you want more than one color, split both the flour and the oil into separate bowls before mixing. That way, each color stays bright and does not end up muddy.
For easier cleanup, I set the bin on a big plastic tablecloth or take it outside. Moon sand stays pretty contained, but a few stray bits always seem to escape.
