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!

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.

Product FAQ

• 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.
