Step-by-step tutorial
Step 1
Add 1/2 tsp of Borax to a bowl. Then add 1 1/3 cups of hot water and stir.
Step 2
In another bowl, add 2 cups of white school glue. Then add 1 1/2 cups of hot water and stir well.
Step 3
Add a few drops of food coloring to get a color that the kids will like and then pour the Borax mixture into the glue mixture and stir.
Step 4
You can use strawberry baskets, but I had this great shopping basket, so we tied this up in our tree and poured the flubber in it. Then I gave the kids children's scissors so they could try cutting the flubber. We put a tub underneath the basket to catch the flubber. Once the flubber ran it's course, we just took the tub and dumped it all back into the basket.
Final result!
You can just see how much fun my daughter is having with the flubber slime. I think in the end, the girls ended up getting most of the flubber on them! If the flubber slime gets on your kid's clothing, I recommend soaking the clothes in warm water for 20-30 minutes to loosen up the glue before sticking it into the washing machine. This is definitely a bit on the messy side, but it's definitely worth it considering how much fun these kids had playing with flubber slime!
