My class has been exploring lights this week. Naturally this means means our light table had to have something interesting and engaging. We decided to make Glow-In-The-Dark Flubber.
The children pulled out the light table toys to stick on the flubber. I loved this little butterfly.
When you press translucent materials onto the flubber, the light shines through from below.
Here is the recipe:
Get yourself 3 cups of glue, 6 cups of hot water (I like to microwave it for a minute...it does not have to be boiling), 2 tbs of borax, glow-in-the-dark paint, 2 bowls, and (optional) a mixing spoon.
In the first bowl, mix 3 cups of glue, 4 cups of hot water, and 2-3 oz of glow in the dark paint. Stir it up.
In the second bowl, mix the 2 cups of water with the 2 tbs of borax. Stir it really well until all the borax is dissolved! Then SLOWLY pour it into the glue water mixture, mixing it with a spoon or your hands. Pour a little, knead it a little. When it starts forming a ball, and pulling away from the sides of the bowl, it is ready to be played with.
Store it in an airtight container. It can be used for weeks if you take care of it.
**Note**The children can help with all of this, but depending on how hot your water is, make sure to have an adult supervising and helping. This recipe contains borax, which cannot be ingested. Be sure to make this recipe with children who are past the mouthing stage (ages 3 and up)!
Invite the children to touch and describe the water-glue mixture before adding the borax mixture. Then ask them how it feels after. They can all help mix with their hands for that sensory experience.This stuff is so much fun to play with!
