MAKE A SELF-INFL ATING BALLOON
Watch a balloon expand thanks to these two reactive kitchen ingredients
1
GATHER YOUR
MATERIALS
The first items you will need are a balloon and a funnel. If you don’t have a funnel, you can create one by making a cone shape from a piece of paper or card.
2
ATTACH THE
BALLOON
Place the opening of the balloon over the narrow part of the funnel. You might need another person to hold this in place for the next step.
3 FILL THE
BALLOON
Pour the baking soda into the funnel. The funnel will direct the powder neatly into the balloon. Then place the balloon gently to one side.
