Permanent Sandcastle Clay

Last week I made some beachy moonsand, but this week I am going to show you how to make permanent sandcastles.

For enough sand clay for one castle, you will need:
1 cup sand
1/2 cup cornstarch
1 teaspoon alum
3/4 cup water

Mix the sand, cornstarch and alum together thoroughly. You can mix them right in the saucepan you will use to cook the clay in. Add the water and stir the mixture until it is smooth and the cornstarch is dissolved. Cook the clay over medium heat, stirring occasionally. The clay should start to thicken within a minute or two. Stir more vigorously, being sure to scrape the mixture from the sides and bottom of the pan. Cook the mixture until it thickens to the consistency of play dough. Remove the clay from the pan and soak or wash your pan or it will harden on it. Once the clay is cool enough to touch, you can start sculpting.

We used items we collected at the beach to decorate them.
One was made with a shell candle in the middle.


The clay may take up to a week to dry completely.
The clay is fragile when it dries so it is better to make thick, heavy structures rather than thin ones.
