To really make it fun make several batches in different colors. You can buy playsand in many colors of the rainbow.
- Mix the oil and cornstarch together thoroughly, till nice and smooth.
- Gradually mix in the sand, one cup at a time. Really work it together with your fingers.
- Just add kids! Let the fun begin! Sand box and beach toys make perfect moulds!
If using water, you'll need to revive it with 2-3 tablespoons of water. Just sprinkle the water over it and work it in.
