Flubber Slime Baskets

I’ve been meaning to do a post on flubber for a while now, but just haven’t gotten around to it.  But just recently in the the past week I’ve seen two sites, Once upon a day in preschool and Familylicious, that have played with flubber using baskets.  It looked like so much fun that I just had to try it out with my kids (and neighborhood kids).

Note: We followed the flubber recipe that Familylicious posted on their blog, however because the kids could not wait for the flubber to cool down, we ended up adding more borax/hot water to thicken it up quicker.  The reason why Familylicious created this recipe, is so that the flubber would remain at a runny consistency even after it has cooled down.  I will post their recipe in this blog post, however I would recommend you wait till it has completely cooled to do this activity.  If you can’t wait, like us however, just mix some more borax with hot water and slowly add it while stirring (watching for the consistency that you want).


  • Borax (can be found in the laundry detergent aisle of any grocery store)
  • Hot water
  • White (school) glue
  • Food coloring
  • Strawberry basket or a toy shopping basket
  • Children’s scissors


Add 1/2 tsp of Borax to a bowl.

Then add 1 1/3 cups of hot water and stir.

In another bowl, add 2 cups of white school glue.

Then add 1 1/2 cups of hot water and stir well.

Add a few drops of food coloring.

Pour the Borax mixture into the glue mixture and stir.

This is the consistency that we ended up with.  It was very runny.

I believe we mixed another 1/2 tsp of Borax with 1/2 cup of water….and we used about 1/4 cup of that to create this consistency.  Can you see the difference? 😉

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.

You can give the kids children’s scissors so they can cut 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.

You can just see how much fun my daughter is having with the flubber.

I think in the end the girls ended up getting the most flubber on them!  If it gets on their clothing, I recommend soaking it in warm water for 20-30 minutes to loosen up the glue before sticking it into the washing machine.
