Sand Slime

Sand Slime


Our family spent a day at the beach this past weekend and my kids had a blast playing in the sand. We decided to recreate the fun at home, but with a fun twist, and made sand slime! The kids loved oozing the sandy goo through their fingers. To add an element of science fun, try experimenting with different ratios of glue and liquid starch to form slime of varying consistencies.

Ages:
3 - 16
Est. Time:
<30 mins

How we did it:

Materials List

  1. school glue (1/2 cup) - white glue works best
  2. liquid starch (1/2 cup)
  3. sand (1 cup)
  4. mixing bowl
  5. craft sticks
  6. measuring cup

    Gather your materials!

  2. Sand Slime Pin It

    Mix 1/2 cup of glue and 1/2 cup of water in a bowl. Mix well!

  3. Sand Slime Pin It

    Add in one cup of sand and mix it together.

  4. Sand Slime Pin It

    Measure out 1/2 cup of liquid starch. Add about half into the mixture and give it a good stir. When it’s mixed well, add in the rest of the liquid starch. Make sure to stir around the edges to incorporate everything together.

    For best results, let the mixture sit for about 10 minutes. (But if you can't wait that long, you can start playing with it right away!)


    Tip:  Store the slime in a zip bag to prevent drying out



    What’s happening?

    The glue contains some super-long molecules called polymers. Adding the liquid starch causes a reaction called cross-linking. Once this happens, the long polymer molecules stick to each other and forms a slime-like consistency!
