A few ingredients and you can make your own "Moon Sand."
Mix 9 Cups of play sand (this is really fine sand I found at Wal-Mart).
Next add 3 cups of cornstarch.
Then add 2 1/2 Cups water. Start with 2 1/4 cups and continue adding the water until you have the desired consistency.
Mix well
You 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!

this looks wonderful!!! i teach preschool and will save this one for sure!
That is awesome. I will definitely be doing this with my kids. THanks you so much for the recipe!
What a great idea! My daughter would love this. I’ll have to give it a try! Thanks!
Awesome! I didn’t know about the play sand!
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!!
very awesome!
thank you soooo much! I love this and the color is awesome!
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!
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!
Cool! I have got to try this!
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.
thank you. we will be trying this out
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
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).
NIIIIIIIICE!!!!!!!!! My kids go through this stuff like crazy. Thanks so much!
This DIY project looks like tons of fun! Before this post I had no idea anyone could make this.
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
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!
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 posted this last summer on my teaching blog it was alot of fun! and much cheaper! plus you can revivie it wil some water!

Great tote tutorial too!!!

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?
