How to Make Flubber

Flubber was a silly movie starring Robin Williams in 1997, but it is also an incredibly goopy craft project that kids will enjoy. What more could a kid want than wiggly, slimy, and gross flubber? Making various types of flubber is enjoyable and simple. Robin Williams would be ecstatic.


Basic Flubber

1 1/4 cup warm water

1 cup any white glue

2 Tablespoons of Borax

Food coloring (optional)

Gak (Borax-free Flubber)

1 cup glue

1 cup liquid starch

Food coloring

Edible Flubber

1 can (14 oz.) of sweetened condensed milk

1 Tablespoon of cornstarch

Food coloring

Method 1 Making Basic Flubber

1. Mix 3/4 cup of the water with 1 cup glue in a bowl. Stir this mixture until it is thoroughly mixed together. Set it aside.

2. Mix 2 tablespoons of Borax with a 1/2 cup of water in a separate bowl. Mix thoroughly until all of the Borax is dissolved.

3. Mix the two mixtures together. They should be mixed together. Add several drops of food colouring until the mixture is the desired colour.

4. Place the mixture in a plastic bag that has a tight seal. Close the bag, making sure it’s tightly shut. After a few minutes of kneading, your flubber will be ready. You can keep the flubber in the bag that you mixed it in.

5. Finished.

Method 2 Making Gak (Borax-free Flubber)

1. 1 cup white glue, poured into a bowl Add several drops of food colouring until the desired colour is achieved.

2. 1 cup liquid starch should be added to the glue mixture. Thoroughly mix everything together. When the glue and liquid starch begin to combine, they should become extremely thick.

3. If the mixture appears too sticky, add more starch. The starch in the glue is what makes it stretchy rather than sticky. Be aware that Gak will adhere to clothing and carpets, but it can be easily removed with a little warm water and scrubbing.

4. Store Gak in a container with a good lid.

Method 3 Making Edible Flubber

1. Pour one can (14 oz.) of sweetened condensed milk into a saucepan. Turn the stove on to a low heat.

2. Add one tablespoon of cornstarch to the saucepan. Stir the mixture over a low heat.

3. When the mixture begins to thicken, remove it from the heat. Drops of food colouring can be added until the edible flubber is the desired colour. The mixture should be stirred.

4. Allow the mixture to cool before playing (or eating). It’s important to remember that edible flubber can stain light-colored clothing and carpets. Warm water and detergent should be used to remove it.

5. Store edible flubber in a container or seal-able plastic bag.
