Anyone heard “I’m boooooorrrrr-ed!” from a kid this summer? Here’s an activity that’ll keep kids occupied for hours on end. You can buy Gak (Nickelodeon’s name for it) at Toys “R” Us, but making your own Slime or goop—or whatever you want to call it—is way more fun. What magic powder turns simple glue into goo? Borax. It hooks the glue’s molecules together, making it into a polymer instead of a liquid. (Actually, according to my Physics/Chemistry major son, it is now a non-Newtonian fluid.)
Kid’s of all ages (like smarty-pants college-age Mitch—those aren’t pre-school arms pictured above…) love the tactile sensation of Slime, and you may have trouble prying it away from adults to let the kids have at it. Just be warned that Slime and fabric are disastrous together, so keep it clear of your favorite tablecloth, jeans, barbie outfits, etc. It should be played with on a hard surface, with plastic or wood utensils or toys. And that’s the end of my disclaimer, so don’t come crying to me when you’ve got Slime stuck in your sleeping bags. (Been there, done that.)
Aside from pulling out this science experiment for bored kids in the summer, I also used to keep an “I’m Bored Jar” on the kitchen counter. Whenever my offspring uttered that dreaded phrase, they had to pick a piece of paper from the jar. They might get a fun activity like making Play-Doh or a marshmallow gun, or they might get a chore like picking up Legos or cleaning mirrors. After vacuuming Mom’s van (kidding…sort of), they learned to entertain themselves.
Makes 1 cup
4 or 7.62 ounce bottle of Elmer’s school glue
(Size of bottle doesn’t make a difference in outcome, but little kids will have an easier time managing the Slime made with 4 ounce bottle.)
2 cups distilled water, divided
10 + drops of food coloring
1 teaspoon Borax powder
1. Pour glue into small bowl. Fill the empty glue bottle with distilled water, leaving a little extra room at top. Add food coloring. (To get a lime green, add yellow food coloring to your water first, plus a few drops of green.) Put cap back on bottle and shake vigorously.
2. Pour colored water into bowl with glue and stir with wooden spoon.
3. In separate bowl, combine 1 cup distilled water and the Borax.
4. Slowly pour the colored glue into the Borax water and slowly stir. You will see globs and strings begin to form. Lift the globs out of the bowl with your hands and knead out water until smooth. Add extra strings of glue as you can, and combine.
5. Store in Ziplock back or plastic container with tight-fitting lid.
