My good friend has two girls, a four-year-old and two-year-old. They have a membership to a hand’s on museum in their area and visit at least once a month. They have a large water table for the kids to play with and there is always science demonstrations going on.


Their absolute favorite demonstration was for something that you can create right in your kitchen. They created Flubber and so can you. My friend said it brings about hours of fun for her girls. This is important because she is a work at home mom too. She is constantly on the lookout for great things that she can make with her kids and I love when she passes them along to me. Here is the recipe for Flubber:

1/3 cup warm water
3 tablespoons Borax (it is found in the laundry detergent aisle)
2 cups warm water
2 cups Elmer’s glue
food coloring (optional)

Add the borax to the 1/3 cup warm water and stir till dissolved. This may take five minutes to happen. Add the food coloring now, if you want the flubber to be colored. In another bowl mix the 2 cups of warm water with the glue and still till dissolved. Add the borax mixture to the glue mixture. Now for the hands on part: mix it all up with your hands. Continue to mix and knead for about five minutes. Thick and sticky fun! It will last for up to two weeks when stored in an airtight container in the refrigerator.

Congrats! You have just made a polymer. I don’t think it will make your car fly but I bet your children will love pulling, stretching and bouncing it. If it dries or gets stuck on anything, some vinegar should help to clean it up.

Have you ever made Flubber? Is it just plain fun or do you try to incorporate a science lesson? I can’t wait for my daughter to be old enough for this one.

Warmly,
Mia
