Clear Slime - PVA Solution

Now you can make our best selling slime in any color of the rainbow. We still supply the PVA (polyvinyl alcohol) and sodium tetraborate (Borax) solutions, but now the PVA is clear. Use your favorite food coloring to make a personalized bottle of slime. Our popular PVA solution contains specially formulated stabilizers to increase the shelf life and keep the slime free of unwanted growing things. This kit makes 15 batches of slime (approximately 60 mL (2 oz) portions).

This is still the BEST SLIME ON THE MARKET! There's just something magical about mixing two liquids together and getting a material that is ooey, gooey, stringy... in a word it's SLIME! This crazy activity has become a staple at teacher conventions, a must for before and after school programs, and the hands-down favorite at Halloween. Recommended for children ages 4 and up with adult supervision.

You get enough materials to make 15, 2 ounce portions or 30, 1 ounce portions of Slime... with a little bit left over!

What's Included?
  • 1-Liter Clear Slime Goo
  • 1/2-Liter Cross-Linker Solution
  • Activity Guide
How Does It Work?

Our slime recipe is based on the classic polyvinyl alcohol (PVA) formula with sodium tetraborate as the cross-linking agent. Doesn’t that sound impressive? Just rattle that off at the next cocktail party and you’ll be the talk of the evening. 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. Turn this ever popular science activity into a real learning experience that is filled with real fun.

What Does It Teach?

Slime is a great hands-on lesson in non-Newtonian solids and liquids and the physics of them. In addition, students will gain valuable knowledge about polymers and their formation.

Customer Reviews

Don't wait too long to use it. Review by Mom

We didn't mix these for months, and they just mixed together to make a mess. Don't wait too long to use them. I'm sure this is a great kit, but it doesn't keep too long.

You're right! A lot of chemicals have a finite shelf life. Try this, though. Give the Worm Goo a decent shaking and try it again. And remember, liquid chemicals are best to be kept in a mild, dry place. Thanks for the feedback and keep experimenting!

Fun and sticky! Review by Astrid

The kids at the party loved it! They were amazed on how when adding the second solution, the "liquid" as they kept stiring began to get thicker. It was a real fun to play with it. (Posted on 3/10/13)

perfect Review by Jason Melvin

The kids (3 and 5) loved it. The elder got the idea of crosslinking and both thoroughly enjoyed playing with slime. My sister already ordered a kit for her son. (Posted on 2/11/13)

A hit with everyone!! Review by Alexandra Huebner

This activity was so much fun, even my 2 year old got a lot out of it. (Posted on 1/11/13)

Awsome slime! Review by Gabby Lantz

I bought this slime b/c i realized its cheaper to buy this and some atomic glow than atomic slime. also you can make other colors by adding food coloring. i made a batch with just atomic glow and another with atomic glow and glow powder. overall, great product i will be buying again soon.

  • How much does it make?
    You get enough materials to make 15, 2 ounce portions or 30, 1 ounce portions of Slime!
  • Is it toxic?
    Nope. However, simply because it is non-toxic doesn't mean that it makes a good snack. Siply ask our product developer Brian. He's still alive and kickin', but it didn't taste very good.
  • 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.
