• 🎈 A grown-up blows up the balloon, and picks up popped bits.
• 🥽 Goggles on
• 🧽 A bit messy

Gather first

• An empty plastic bottle · 1, a water bottle is fine
• A balloon · 1, white
• 🖍️ Crayons or markers · a black marker
• White vinegar · 1/2 cup
• Baking soda · 2 teaspoons
• A small funnel, or a paper cone
• A spoon
• A measuring cup

The big idea: Baking soda and vinegar make a gas, and the gas blows up a balloon all by itself.
