Sand dough is a great choice for recycling the pretty clean sandbox sand that remains in your sandbox at the end of the season, which is when we usually make it, but I can imagine that it would also make a super-fun beachside project, perhaps even your own sandcastle souvenir, complete with seashells and a moat ready to be filled with salt water.
Even for play dough aficionados, sand dough has a terrifically gritty texture that provides an entirely new sensory experience to the act of working with the dough, and it can be an excellent component to a sensory table for a special needs child or as a teaching tool for a tactile learner—use it in conjunction with the sawdust dough for two very neat and unusual experiences.
Approximately 4 cups of clean sandbox or beach sand
Approximately 3 cups of plain, cheap flour (we use the bleached kind here, because it’s cheap-o)
One-quarter cup of plain cooking oil (again, we have a stash of super-cheap oil that we use just for making our own art supplies)
One-quarter cup of cornstarch (baby powder will do, too, if you have any that you want to use up)
At least one cup of water, although you may need more
Mix everything together well, and then knead it by hand. Depending on the consistency of the sand that you use, you may need to add more water to this dough. The rule of thumb: if the dough is too sticky, add more flour or sand; if it’s too crumbly, add more water.
This sand will dry out quickly, so store it tightly covered when you’re not playing with it.
