How do you make flubber without borax?

To make borax-free flubber, mix water and psyllium-based dietary fiber together with food coloring. Heat this mixture several times in a microwave, then allow it to cool off.

1. Mix fiber and water in a bowl

   Mix 1 teaspoon of a psyllium-based dietary fiber supplement and 1 cup of water in a microwavable bowl. To make the flubber a specific color, mix in a few drops of food coloring.

2. Microwave the mixture

   Microwave the mixture on high for four to five minutes, or until the mixture looks like it is rising up out of the bowl. Remove the bowl and allow the mixture to cool down for a few minutes. Repeat this process four to six times or until the substance has the desired consistency.

3. Allow the mixture to cool

   Pour the mixture onto a cookie sheet, glass platter or plate, spreading it out evenly. Be careful not to get any of the mixture on bare skin, as it is very hot. Stir the mixture consistently while it cools off.

4. Cut into shapes

   Once the flubber is completely cooled off, use a knife or cookie cutter to cut it into pieces.

5. Store the flubber

   Store the flubber in plastic bags to keep it moist. Storing the flubber at room temperature keeps it fresh for several months, while refrigerating it keeps it fresh much longer.
