When I got this month’s issue of Family Fun Magazine, one of the summer activities was a RECIPE for air-hardening Sand Clay, I knew right away that the boys would love it, especially just coming off of our beach vacation!
They got to work right away mixing up the ingredients: sand, cornstarch and water (we didn’t use alum as called for in the original recipe because we didn’t have any on hand). We also added some gold glitter to our mix to give it a little extra sparkle. NOTE: Be sure to use an old pot to mix up your clay, as the sand will scratch the heck out of one of your nice pans!
Cook it over the stove for a few minutes until it reaches a Play-Doh-like consistency.
Now play, shape, squeeze and mold to your heart’s content!
We let our clay air dry, so it took about three days for it to completely harden up, inside and out. If you want to speed up the process, you can also bake it in a 225 degree oven for a few hours.

Recipe??? please you wrote what ingredients to use but now how much
To get to the original recipe linked in the post, CLICK HERE (for detailed directions) or the basic recipe is as follows: 1 cup sand, 1/2 cup cornstarch, 1 tsp alum (we omitted because we didn’t have any, and it worked fine), and 3/4 cup of water.
What an awesome idea! We’re actually going to the beach in a few weeks. I think we might make this when we get home to use some of the seashells we collect.
Thanks so much for sharing at my Summer Fun party!

What a great idea – thanks for sharing. I found your site from a linky party, and I’m enjoying browsing. I’m a work-at-home mom, too, with 2 boys (a bit older, though). My youngest would definitely enjoy this project.
this is great! I made beads with sand and glue last year that were great, would you be so kind as to share the recipe? all the best!And good luck with the new blog, I can see it’s going to be great!
I love this way to save a little piece of summer for all year round. I host a weekly Show and Tell at my other blog and I’d love for you to link up: http://www.abcand123learning.com/2010/07/show-and-tell-15.html
