• 🚫 Not food! Never taste it, and wash your hands when you're done.
• 🥽 Goggles on
• 🧽 A bit messy

Gather first

• Paper cups · 1
• Paper · 1 sheet
• 🖍️ Crayons or markers · a brown one
• A baking tray or big plate · to catch the lava
• Baking soda · 2 tablespoons
• White vinegar · 1/2 cup
• Dish soap · a squirt
• Food colouring · red, a few drops
• A spoon
• A measuring cup
• 🩹 Tape
• ✂️ Kid scissors

The big idea: Baking soda and vinegar make a gas, and soap turns the gas into foamy lava.
