How to Make Silly-Putty Out of Flour and Baking Soda

Updated April 17, 2017

Silly putty is a bouncy, mushy, bendable substance that was introduced to the public in 1950 by Peter Hodgson, an employee of General Electric. Originally called nutty putty for the putty's ability to stretch and break into thin strips, the name was changed to Silly Putty by Hodgson. In the 1980s, Silly Putty became incredibly popular and has remained a childhood staple ever since. Instead of buying the putty in the plastic eggs, now there are recipes to make it, using common household products.

Pour the flour into a bowl. Add eggs to the flour. Mix thoroughly.

Add the glue to the mixture slowly. Continue to mix.

Add a few drops of food colouring and mix. Pour in 236ml of water and mix.

Add a few more drops of food colouring into the mixture if it is too light.

Mix baking soda, cornstarch and 1 1/2 cups water into a bowl.

Boil over medium heat, uncovered.

Spoon onto waxed paper and let it dry.


This is a great recipe to make at a small kids party and gives everyone who comes to the party something to take home with them.


Do not use the hob without adult supervision.
