As part of our Halloween activities this afternoon, we made some Bubbling Witches Brew.
First we half filled a bottle with vinegar.
Next, we added either red or yellow food colouring and some glitter.
To help make it bubbly, we put in a good squirt of washing up liquid.
Lastly, we added some bicarbonate of soda and watched the mixture bubble up. It made quite a mess but luckily we had put the bottles on a tray to catch the brew.
