Using Liquid Starch

2:1 ratio of white glue to liquid starch

Bowl

Spoon

Resealable container

Food coloring (optional)

• Mix two parts white glue with one part liquid starch. The liquid starch (e.g. Sta-Flo) should be concentrated and can usually be found in the laundry section. Some brands will work better than others (Niagara has tested poorly).
• If you use Elmer's school glue (an American brand of glue) instead of reg
• ular white school glue, the putty won't bounce. However, Elmer's all-purpose glue will work.
• If you'd like, add food coloring in at this stage. Be generous -- the color will disburse and lighten up significantly.
• Stir until desired consistency is reached. If you need to, adjust the proportions until it feels like commercial Silly Putty.
• When it's mostly formed, take it out of the bowl and shape it with your hands. It may need to be worked with a bit to achieve the best results. Roll it around, stretch it apart, and contort it to get it going.
• Place in a clear, plastic, resealable container when you're finished using it. To keep it for later, your putty needs to stay away from air. It will also keep for a longer period of time if kept in the refrigerator. Alternatively, keep it in a resealable plastic bag. Just make sure it's sealed up all the way!
