Sandcastles Forever

Free Custom Photo Calendars

Bring home some sand and shells from your beach trip and use them to make a sand castle that won't fall apart! If you like this craft, you’ll also like our Sandbox Dinos - a which you can bring with you to the beach.

What You’ll Need:
*1 cup of sand
*1/2 cup of cornstarch
*3/4 cup of water
*small piece of paper
*glue or tape

*Did You Know? Sand is actually tiny rock pieces that have been eroded by water. Some sand grains are the same color as nearby rocks. You may find a lot of light-colored or even clear particles. Many of these are quartz. Because sand has a lot of quartz, it is used to make glass. Use a microscope to look at your sand up close. Do you see any dark particles in your sand? Get a magnet -- the dark particles are probably iron-rich and will stick to the magnet!
*Parents: Heat the cornstarch and water on a pan on the stovetop until thickened, stirring occasionally. Add the sand and stir until combined. Allow to cool.

*Mold the COOLED sand/water/cornstarch mixture into shapes for your sandcastle. Decorate with shells.
*Cut a small triangle out of the paper and glue or tape to the toothpick to make a flag.
*Send us a picture of your kids and their sandcastles and we may post it to our site!
