There are numerous recipes for homemade silly putty, so I have included three.

Recipe #1:
2 parts Elmer’s Glu-All Multipurpose (NOT school glue)
1 part Sta-Flo liquid starch (NOT Niagara)
Mix glue and starch together. Sit and let stand 5 minutes. Pour onto paper towel and knead 5 to 20 times. Store in air tight container. Zip-loc work well.

You can color any recipe with 1 drop of food coloring, but it will stain hands and table tops.

Recipe #2:
1 cup Elmer’s Glu-All Multipurpose (NOT school glue)
8 tablespoons liquid laundry detergent
Mix together and stir well. If sticky, add more detergent. Knead several times. Store in air tight container, and if kept in a refrigerator, it will last longer.

Recipe #3:
1 cup cornstarch
4 cups water
Boil the water. Add cornstarch a little at a time, while stirring. Remove from heat and allow to cool. Store in an air tight container.

These putties provide a wonderful tactile experience. They can simply be held and squeezed, they can be stretched, or they can be placed on top of an upturned plastic cup and left to ooze down the side. Be creative!

(Silly putty can stick to fabrics, so asking participants to wear paint shirts is a good idea. It will not stick to hands, but might stick to jewelry. If a participant wears multiple rings, they may want to remove them.)
