Silly putty, also known as nutty putty or bouncing putty, is a silicone-based novelty product often enjoyed by children for its unique characteristic of behaving like both a solid and liquid. To save money, or as a fun classroom or rainy-day project, make your very own silly putty with corn starch and a few other affordable household supplies.
Things You'll Need
- Medium-sized bowl or container
- 1 cup corn starch
- 1/2 cup water
- Food coloring (optional)

Making the Putty
Add the corn starch to your bowl or container.
While slowly mixing the corn starch with a spoon, slowly add the water to the bowl until the mixture reaches a gooey, runny consistency.
Add a few drops of food coloring to the mixture and mix until the color is evenly distributed. This step is optional, but adding color is fun if you are doing this project with children. Plus, it makes the product look more similar to the store-bought kind. Add as much or little food coloring as you want, depending on how intense you want the color.
Using the Putty
Dip your hands into the mixture and pour it through your fingers to observe its properties. When the mixture is free-falling through your fingers, it will feel wet and runny. However, if you poke or strike the substance, it will feel hard and plastic-like.
Store the putty in an air-tight container or sealed plastic bag to preserve for later use.
