the other day we made flubber. i found the recipe here.
first, we mixed warm water and glue together.
in another bowl we dissolved borax in warm water. once it was dissolved, we added the glue mixture to it. it had a chemical reaction and the flubber was created. we added food coloring to make it green.
keep it in an air tight container when the flubber is not being played with. my kids have loved playing with it!
