Product FAQ

  • Is it toxic?
    Nope. However, simply because it is non-toxic doesn’t mean that it makes a good snack. Simply ask our product developer Brian, he’s still alive and kickin’.
  • Does it stain?
    No, you should be good.
  • How long will it last?
    After it is made, it will start to dry out unless it is in a zipper-lock bag or some other airtight container. It also depends on how well it is treated. Make sure that your wash your hands before playing with it. The un-mixed solution has a shelf life of about a year.

Fun Slime!

We purchased this slime for our son's 5th birthday party. The kids had such a good time mixing up the slime mixtures to make their own gooey slime. They made the slime in cups that came with lids so that they could take it home with them. Days of fun, I'm sure.

Solids, liquids, gases! Oh, my!

By the time my students have reached 6th grade science, they've heard everything there is about the way atoms behave in a solid, or a liquid, or a gas but it is still part of my curriculum (and oddly enough, they still don't quite "get it"). Best lesson EVER for this: give them something that doesn't behave like just a solid or just a liquid! We make quantitative and qualitative observations with our slime. We try to classify it as a solid or a liquid. Most importantly, we play with the recipe to see how to make the "best" slime (stretchiest, slimiest, etc.)

Although I've purchased PVA elsewhere and even used my own school glue recipe, this is the BEST slime I've found. My kids think so too!

Best Slime Ever!

This slime is the hit in all our afterschool programs with students of all ages! Even the adults accompanying the kids ask to make some. We have tried at least ten different "recipes" for slime and found this to be the very best. Thanks!

Party favorite!

This was one of 4 experiments I had planned for the kids at my son's 5th birthday party.
The kids were enthralled with the slime and it totally captivated their attention.
I also let them all take a batch home with them which they loved!
What 5 year old doesn't LOVE getting their hands dirty?

The hit of the party!

purchased 2 kits for my childs halloween party. I devided up cups and helped each child make their own slime to take home. I have already refered several parents to this website because of the slime. It is easy to make, the fact that it was transparent (unlike the glue slime)was what all the kiddos kept talking about.

I would love to know how to make it "runny" it does end up like soft jello. A+ Steve!
thanks-AZ momma
* oh, fast safe shipping too!

We got this for our sons 12th Birthday/Halloween party as a "fright box" oddity. The kids LOVED it and each of them insisted on taking some of it home.
Super easy to make! And the slime lasts quite a long time.

Easy and Fast

I got this for my child's birthday party and all the kids loved making the slime and playing with it. They pretended to make slime popsicles, pasta, necklaces with their slime. We also got the shaker cups and lids to ensure that the kids can easily mix their slime and bring their slime home.

The 2nd graders loved making the green slime shakers, however I forgot to order the glow in the dark additive. We will definately be ordering more kits in the near future. Thank you for making science fun

Slime is a fun and exciting product for all ages. You can mix it together and watch it stretch, when you pull hard it will break but if you pull slowly you can watch it stretch. The slime is a polymer that is linked together with long chains of molecules. This slime is non toxic and will not stain anything. With this kit you can make about 30 1 ounce portions of slime or 15 2 ounce portions of slime.
