DIY Flubber Recipe
2 1/2 cups water, divided
3/4 cups Elmer's glue (one 225ml bottle)
2 tablespoons Borax
1. In a large bowl, slowly mix 1 1/2 cups water into the glue until combined. Add a few drops of food coloring if desired and mix well.
2. In a small bowl, mix together remaining 1 cup of water and Borax until the Borax is completely dissolved. (I do this in my liquid measuring cup so it is easier to pour)
3. Slowly pour the Borax mixture into the glue mixture a little bit at a time while mixing with a metal spoon or your hands. (*NOTE: you probably won't need to use all the Borax solution, I only used about half) As you mix, a flubber ball will start to form. Once there is no liquid left from the glue mixture, discard remaining Borax solution.
4. Stretch it! Cut it! Try to blow bubbles in it with a straw! Store in an airtight container or ziploc freezer bag for about a month. When it starts to get to hard or crumble apart, it's time to make a new batch.
