This slime is similar to the one above, but creates a less rubbery and more transparent slime. Store it in a plastic bag in the fridge, to keep it from growing mold. This kind of slime will get stiffer and more like putty the more you play with it. The borax links the polyvinyl acetate molecules to each other, creating one large, flexible polymer. The glue has an ingredient called polyvinyl acetate, which is a liquid polymer. (No one makes slime without getting a little messy!) Don’t worry about any leftover water in the bowl just pour it out. The slime will begin to form immediately stir as much as you can, then dig in and knead it with your hands until it gets less sticky. Add the glue mixture to the borax solution, stirring slowly.Ĥ. In the other bowl, mix 1 teaspoon borax with 1 cup water until the borax is dissolved.ģ. Add food coloring if you want colored slime.Ģ. In one bowl mix 1/2 cup (4 oz) glue and 1/2 cup water. Borax (find in the laundry detergent aisle of the store)ġ.Elmer’s white glue or Elmer’s school glue gel.Make it with white glue for opaque slime, or glue gel for translucent slime.
Slime and putty how to#
Who doesn’t like to play with something gooey and squishy and, well, slimy, every once in awhile? This issue will show you how to make slime with household ingredients, or how to step it up a notch with a liquid polymer called polyvinyl alcohol. Making slime has long been a favorite chemistry activity. Take a holiday from “serious” science and have fun with these slime recipes or get a slime science kit! Plus see the amazing properties of Thinking Putty in our Thinking Putty video.
