Silicone putty is known by a variety of brand names, which include Silly Putty and Tricky Putty. The product was originally discovered in an attempt to create a rubber substitute to be used during World War II. Silicone putty can be in a liquid or solid form and can be stretched, broken, bounced, formed, used as an adhesive or used to transfer petroleum based ink images.
Place two plastic containers on a flat surface in front of you. Label one of the plastic containers with "Borax Solution" using a permanent marker.
Unscrew the cap of the glue and empty all 227gr. into the unmarked plastic container. Fill the empty glue container with water, replace the lid and shake the water in the bottle until all of the glue is pulled away from the edges of the container. Empty the water and glue mixture into the plastic container. Stir the content of the container with a plastic spoon.
Measure 1/2 cup of water and pour it into the "Borax Solution" container. Measure 1 tsp of Borax and add it to the same container. Stir the solution with a clean plastic spoon until mixed well and all of the powder is dissolved. Allow the mixture to sit for a few minutes if the powder does not dissolve with mixing alone.
Slowly pour the Borax mixture into the glue mixture, stirring constantly. When stirring becomes difficult with the spoon, begin stirring with your fingers. Continue mixing and kneading the material as it hardens.
Transfer the putty into a plastic bag when the consistency stops changing. Squeeze out any excess air and seal the bag closed.
Add more glue in small amounts and continue kneading the product if you want a harder consistency. Food colouring can be added to the mixture at any point in time to change the colour of the silly putty. Add small amounts of food colouring at a time. Follow the colour combination recommendations on the food colouring package, increasing the food colouring amounts until the desired shade is achieved.
Exercise caution while measuring and working with the Borax solution. Do not inhale the powder or rub your face during handling. Keep the powder and the solution away from children and pets to avoid ingestion and serious medical problems. Supervise children when playing with silicone putty to prevent ingestion.
