It's gooey, slippery, sticky, really slimy and kids go crazy for any teacher who makes slime. Throw a slime day and you'll be an instant hit. But don't forget that there's learning underneath all of the stirring and mixing. Making slime is a great way to learn about concepts like states of matter, cross-linking of polymers, material synthesis, chemical bonding and more. Try your hand at using slime as a writing prompt to get those creative ideas flowing.  

This kit comes with everything you need to make 64 ounces of the best slime on the market today. You'll also receive 24 mixing cups, stirring sticks and zip-lock bags for students to take home their perfect batch of slime. 

Our slime recipe is based on the classic polyvinyl alcohol (PVA) formula with sodium tetraborate as the cross-linking agent. What makes our slime formulation unlike anything else on the market is the addition of our stabilizing agents that help to reduce the growth of bacteria while preserving the stretchy, stringy, gooey properties of slime that everyone loves. Don't settle for imitations and risk disappointing your students. Spangler Science continues to supply Hollywood's top special effects artists with these tried and tested ingredients that are as safe to touch as they are fun to squish. 

Recommended for ages 6 and up with adult supervision.

Product FAQ
  • How much does it make?
    You get enough materials to make 24, 2 ounce portions... with a little left over!
  • 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 you wash your hands before playing with it. The un-mixed solution has a shelf life of about a year.

  2. Excellent value, easy to do... review by DD on 3/17/2013

    I liked this kit as it came with all the extras.. popsicle sticks, little cups, and instructions are easy to follow for even young students.

    The slime is great, safe, and this kit is a much better alternative to buying elmers glue and borax.

  3. slime classroom kit review by marta on 1/17/2013

    The end product was great. A bit stickier than expected...ended up using hand lotion on our hands before handling the product and that worked wonders. The only problem I had was the method of mixing. The online video clip recommends using a cup with cap and shaking the mixture together, yet the kit only provides cup with popsicle stick which is significantly more messy. I ended up picking up plastic cup lids from the local taqueria's salsa bar. That imporved the experience for our second batch of slime.
