Your silly putty will turn the same color as the dish soap that you are using. If you can a certain color, stir in a few drops of food coloring into clear dish soap., How much glitter you use is up to you. A few spoonfuls should do. Try to use the extra-fine glitter rather than the chunky kind. It will make your putty look more like the store-bought kind!, Stir everything together with a spoon, then switch to using your hands. At first, you will get a crumbly mixture, but then it will turn into a gel the more you work with it. Don't worry if there is some corn starch or dish soap at the bottom of the bowl.If it is very dry in your home, you may need to add more dish soap.
If you can't find cornstarch, look for cornflour (not cornmeal).
 It will be sticky and gooey. You may have some liquid left at the bottom of the bowl, which is normal., You can stretch it, ball it up, and bounce it. When you don't want to play with it any more, put it into a plastic, zippered baggie. You can also use a plastic box with a lid instead.
Pour ½ cup (120 milliliters) of dish soap into a bowl.
Add some glitter, if desired.
Mix in 1 cup (125 grams) of cornstarch.
Knead the mixture until the silly putty comes together.
Play with the putty.
