EQUIPMENT: Saucepan, Food colouring, Spatula, Stove, Water, Glycerine (from a pharmacy), Vinegar, Tin foil.
- To start, take your saucepan and add four saucepan and add four tablespoon of starch. Add a teaspoon of vinegar and glycerine to the mix and stir vigorously until it is completely mixed together.
- Take the saucepan and place it on the stove on a low heat. Stir the mixture continuously as it warms up. As the mixture heats it will transform from a murky liquid into a clear gel. When the transition is complete, the gel should be transparent.
- When the gel turns clear and begins to bubble, mix in your food colouring. Take the pan off the stove and spread the gel across a sheet of tin foil into any shape. Make it as thin a spread as possible. Leave the tin foil in a safe place for 24 hours. If the experiment has been conducted properly, after this time the gel will have hardened into a sheet of homemade plastic.
