According to the Silly Putty website, the iconic substance began in a lab in 1943 as a failed formula for synthetic rubber. Seven years later, Peter Hodgson packaged the stretchy goo in a plastic egg and christened it Silly Putty. Since then, many parents and teachers have concocted recipes for a homemade version of the putty. Unfortunately, most of these mixtures contain glue, which can be messy or even toxic. You can make a clean, safe silly putty instead.

    Combine the water and vegetable oil in a small cooking pan.

  3. 3

    Slowly blend the dry ingredients into the cooking pan. Whisk the mixture until it is lump-free.

    Use the wooden spoon to mix the remaining dry ingredients into the pan. The mixture should have a soupy consistency.

  5. 5

    Cook the mixture over a medium heat until it reaches a doughy consistency.

  6. 6

    Remove the mixture form the heat. Allow the dough to cool for one hour on a sheet of aluminium foil.

    Store your silly putty in an airtight container.

Tips and warnings

  • Customise your putty by adding food colouring to the water and oil mixture.
  • To keep your silly putty fresh and germ-free, place three drops of hand sanitiser into the airtight container before storage.
