To make your own Wizard's Brew
you'll need:


a clean glass jar/s


white vinegar


food dye


glitter


dishwashing liquid


baking soda



STEP 1: half-fill a glass jar with clear vinegar. Add several drops of food dye, then sprinkle a little fine glitter over the top of the vinegar.


STEP 2: Add a good squeeze of dishwashing liquid to the jar. Then, gently stir the mixture with a metal spoon to mix everything together.


STEP 3: Put the jar in the middle of a large baking tray or a sink. Add a heaped teaspoon of baking soda to the jar and see what happens.


~~~~The foam that pours out of the jar is formed by a simple chemical reaction. When the vinegar and baking soda mix, they make lots of tiny bubbles of gas. The bubbles churn up the dishwashing liquid, making lots of foam!~~~~


Have Fun!
