dioxide given off by a baking soda and lemon juice reaction by funnelling the gas through a soft drink bottle. Blowing up balloons was never so easy! | | | | What you'll need: * Balloon * About 40 ml of water (a cup is about 250 ml so you don't need much) * Soft drink bottle * Drinking straw * Juice from a lemon * 1 teaspoon of baking soda Instructions: 1.
