- 4 tablespoons baking SODA (not powder) - this is also known as bicarb soda
- 2 tablespoons white vinegar
- 2/3 teaspoon glucose syrup (available at supermarket in baking aisle)
- 2 tablespoons corn flour (available at supermarket in baking aisle)
- Food colouring (icing gels work best, but the normal Queens brand liquid from the Supermarket is fine - we like to buy the 4 pack of red/yellow/blue/green)
- Mini muffin or ice cube tray
- Toothpicks or something else to stir with
1. To make your paints, first mix the baking soda and vinegar together in a big jug. The next steps are easiest if it's a jug with a spout, like a Pyrex measuring cup.
2. Wait for the fizzing to stop, and then add in the glucose syrup and corn flour. Stir, stir, stir!
3. Pour into your containers (DO NOT add the colours just yet!). This mixture will be VERY thick - that's ok. That's what it is meant to look like.
4. Add a few drops of colour to each container and stir through with a toothpick.
5. Let them dry! This will take at least a day.
To make your watercolour painting, you'll need a paint brush, a glass of water, and some thick paper. Try seeing if you can make a colour combination like the ones in The Star in the Forest!
