When dry, these opaque little balls are available in three sizes: 1 mm, 2.5 mm and 4.0 mm. When placed in warm water for several hours they swell up to several times their size! The 4 mm balls turn into perfectly clear little spheres of 1.5 – 2.0 centimeters. They even bounce when you throw them on the floor!

SAP Spheres

MAKE YOUR OWN COLORS!!!

Here's how to dye SAP Spheres & create your own colored spheres:

Supplies needed:

1.  SAP Spheres
2. Distilled water.  (Tap water works but distilled water makes spheres grow bigger.)
3. Vegetable Food Coloring / Egg Dye
4. Dish Detergent

  • Take 1/2 gallon of distilled water (or tap water) and warm up lightly on stove or in microwave.  (This speeds absorption.)
  • Add 10 -12 drops of food coloring (more or less depending on how intense you want the coloring)
  • Add 2-3 drops of dish detergent.  (The surfactant in this helps the dye to be absorbed into the SAP Sphere.)
  • Stir lightly and add 1 teaspoon of SAP Spheres.  Let stand & soak overnight.
  • Viola!  You now have colored SAP Spheres!

NOTE:  You can also add fragrance to the SAP Spheres using the same ingredients and method.
