How to make kinetic sand?​

This recipe is interesting because it combines the unique characteristics of cornstarch and water, with the moldable characteristics of sand. You know how when you mix cornstarch and water it’s not quite a liquid and not quite a solid? Adding it to the sand kind of gives the it a bit of a “quicksand” quality, especially when you add more water to it.This recipe uses water, corn starch and dish soap (the full recipe is at the bottom of this post). The soap is what gives it the fun squishy texture.This recipe uses water, corn starch and dish soap (the full recipe is at the bottom of this post).

Mix together the sand and corn starch. It will make it easier to combine when you add the water and will prevent lumps if you pre-mix the dry ingredients.Add the dish soap to the water in a separate container and stir until it’s well mixed and a little bubbly.Then add the water and soap solution to the sand and corn starch mixture.Stir it up until it’s well mixed. If it looks a little too dry, feel free to add some more water until it gets to a consistency you like.This stuff had a great texture! It was easily moldable, and I would say it behaved a lot like the kinetic sand you see in stores. Out of the three recipes we tried, this one was probably the best, with the oil and flour moldable play sandbeing a close second.
The only problem with this recipe was that by the end of the day, it had completely dried out. Which I guess is either a good or a bad thing, depending on how you look at it. If you put it away after it has dried out, it will store so much better and all you’ll have to do is add the water back when you are ready to play with it again.

Answer:

Materials

About 10 pounds (5 cups or 4.5 kilograms) of play sand

1.2 cups (1 cup plus 3 tablespoons or 130 grams) of cornstarch

1/2 teaspoon (2.5 milliliters) of standard dishwashing liquid

1 cup (236 milliliters) of water

1 large and 1 medium bowls for mixing

Airtight container for storage

Directions

Place sand in a big bowl.

Add cornstarch to the sand and mix.

In a separate medium bowl, mix dish soap with water.

Add the soap mixture to the sand and combine thoroughly.

Note:

Play sand is available at craft stores. It's better for this project than scooping up sand from the playground or beach. Also sand should be completely dry before staring. You can bake it a 1-inch deep layer at 250 degrees Fahrenheit (121 degrees Celsius) for about 30 minutes to ensure total dryness. Then allow to cool completely.
