We made this in my child's Kindergarten class, and I was honestly prepared for a catastrophe. I pre-measured the glue in gallon size ziplock bags (sitting in a large bowl in case of spills or broken bags) and waters in water bottles. We also tinted the water that mixes with the glue. Pre-measured the Borax in disposable condiment cups. We had 4 children at a table. One student held a plastic cup. Into this cup, one child poured Borax, another the clear water. A third child added the colored water to the glue bag. They all had a chance to knead the glue mixture. Then the child with the cup of water and borax mixture poured it into the glue bag. All children had an opportunity to gently knead the Flubber before we divided it into individual ziplock bags to take home. I didn't worry about making sure the Flubber was "dry" before putting it in take home bags, and by the time we were home, all water was absorbed. Most shocking element, an independent group project and hardly any mess.
White vinegar can be used as a solvent if you get this in your hair, clothes, or carpets! :)
What fun! We made this when ds had a friend over - they were fascinated by the process and played with it all afternoon. There IS water left in the bowl - no problem with that, just so people know. It 'dries' up (but still feels cool & slick) quickly after being taken out of the water - but until then be careful of clothes & furniture (found some dried/stained on a chair cushion). And be prepared to clean up kids hands & extra water.
Awesome!!, my boys are having a blast with it, made it in neon green food coloring...they want neon blue next. I did have about 1/2 cup of water left in bottom of bowl. Thank You very much Breeze144!
