DIY Moon Sand

    Posted by  ·  July 15, 2009


    A few ingredients and you can make your own “Moon Sand.”

    moonsand1Mix 9 Cups of play sand (this is really fine sand I found at Wal-Mart).

    moonsand2Next add 3 cups of cornstarch.

    moonsand3Then add 2 1/2 Cups water. Start with 2 1/4 cups and continue adding the water until you have the desired consistency.

    moonsand4Mix well

    moonsand5You can experiment with the ingredients until you get it exactly how you like it.  Be careful though, it is very easy to get sandy oobleck! When finished playing, cover and store. Next time you play add a few tablespoons of water if it needs to be moistened.


    It isn’t exactly the perfect moon sand but it is close (much cheaper and even the real Moon Sand did not meet my kids expectations) and my kids had a great time!

      Could you use decorative sand like what they use for unity ceremony's?

      I googled this on a different website for other ideas and one suggested adding 1TBSP + 1 tsp cream of tartar to help preserve it and help prevent molding. You can buy the fine sand at Michaels in lots of different colors too. Haven't checked the price of the sand at Michael's, but was suggested to buy the play sand at Home Depot or Lowes which sells it in 50lb bags for less than $10.00.

      Made this to use with children I work with at the local elementary school. Maybe I did something wrong, but it didn't turn out good. When we made it, it was a perfect consistency, but every time I opened the container, there was liquid standing on top of the sand and the sand was drier than it needed to be. We would have to mix it up really well. Whenever we did play with it our hands were left with a white residue (I assume from the corn starch.) But, we were outside on the playground, so we couldn't wait to get inside and wash our hands. Maybe I will try again sometime.

      Does the water have to be a specific temperature?

      I think my recipe is a bit cheaper and you probably have everything in your kitchen. I made it a few years ago and just recently threw it away when it got wet. If you keep it on an air tight container it will save for a long time.
      3 cups a/p flour
      1/2 cup vegetable oil
      food coloring
      Mix food color with oil first making it much darker than you want it to end up. In large bowel, combine oil and flour; mix thoroughly with your hands. If it’s to dry add 1 or 2T more oil (you can use this as a chance to add more color if needed. Keep it away from carpet and water and store it in an air tight container.
      ? Kool-Aid for coloring and scent (haven't tried this suggestion yet)

      Just tried this out with my kids. It was enjoyed but I discovered a fun error. Seems I added to much water and we ended up with "Alien Goo"...we use the green Crayola sand. The consistency was very odd, almost like Goop. Try it if you dare.

      Ugh! We were so excited to do this, and perhaps rushed a bit. Our sand was VERY moist from the store (same sand you used) and it was VERY humid out... so we have a watery, sloppy mess. I'll have to wait to evaporate some of the water off. :( Thanks for the recipe though! Hope we can save ours.

      This is such a great idea and my kids LOVED it. We made blue and it turned out perfect.
    12. What to THEY Use
      Sunday, March 7th, 2010
      So while this looks like a fun project, I don't think its much like "the real moon sand". On their website, it says that if you get water in it, to let it "dry out" on a paper towel and that after drying, moisture will return to it.

      Also above, someone said that when they returned to play with it, it was covered with mold! Thinking about this, it's no wonder. They actually use a corn-starch like substance for petri dishes!

      If you make the above, consider it disposable, throw away after a few days. It reminds me of the huge batches of "play dough" my mom made me as a kid. Fun in bulk, but didn't last long.

      Anyone have any idea on how they really make it?

      I love it when you can make it yourself. I came to dislike moon sand when it was impossible to clean off my table...its stayed there forever. I look forward to trying this one kids will love it...outside :)

      My kids are so going to LOVE this!

      Okay, yours is a seriously awesome blog! :) I'm so glad I found it this afternoon (was doing a search on why my amish friendship bread starter doesn't freeze solid!)!!!!!!!!!!!!! I am definitely going to try making gak and oobleck :) Is there a way to make gak using non animal-based glue do you know? I'll have to check that out!! I don't have kids but I'm sure my husband and I will be fascinated by this stuff anyway :) Great tote tutorial too!!!

      That is so neat! I am saving that for the recipe files for sure. My kids love moon sand. But it is expensive for the amount of sand you need.

      I have tried making my own moonsand in the past. After storing it for a couple of weeks, it was covered in mold. We may not have played with it enough and let it air out, but it was really gross. Just an FYI.

      I told you on Twitter that I loved this idea. And then we tried it! My 5 year old son loves it! The only issues - I was being so frugal that 1) we used sandbox sand...too grainy and 2) I let them put food coloring in to make it pretty. ha!! My son's hands were bright green for two days!

      Seriously - thanks for a fun project!

      Love this! We spend a lot of $$ on moon sand for the preschool and I have grandkids who love the stuff. They will love the experience of making it too.WOW

      This DIY project looks like tons of fun! Before this post I had no idea anyone could make this.

      NIIIIIIIICE!!!!!!!!! My kids go through this stuff like crazy. Thanks so much!
    23. Thursday, July 16th, 2009
      I think I like your idea of a container best of all! We have some of the moon sand and have no idea how to drag it out without having the kids take it from one end of the house to the other (or dumping it all).

      Loved this recipe to do with my 5 grand children and I am going to try it for an activity and hand exercise for my elderly residents at my rest home. I am the activity director. thank you
    25. Wednesday, July 15th, 2009

      That's a great idea...we are celebrating 7/20, Neil Armstrong landing on the moon and this will be great. I saw this recipe on a money saver site and it looked fun, glad to see someone that has actually tried it. Keep up the good work.

      Thanks so much! This looks fun, my daughter is always wanting me to buy this for her. We homeschool, so this looks like a fun project to try. One question, does it try up after time? How long does it typically keep?

      Thanks again for another great tute!

      Totally cool, we've never played with real moon sand, but this looks like a lo t of fun. We'll have to try it! Thanks for sharing!

      Very cool, and very timely too! Did you know that this upcoming Monday 7/20 is the 40th anniversary of Neil Armstrong landing on the moon? I'm making "moon pies" to celebrate, but will now have to make up a batch of moon-sand!! Thanks a bunch!!
    33. Wednesday, July 15th, 2009
      Awesome! I didn't know about the play sand!
    34. Wednesday, July 15th, 2009
