Are you dreaming of decorating your house for a festive party with flying balloons? "With your own hands" does not offer to buy expensive helium balloon… We'll go the other way!
How to inflate a flying ball
It will be especially interesting for children to participate in this business, so feel free to involve them in the process! Do not forget just before starting the experiment to put on aprons and rubber gloves: all the components are simple, but safety engineering nobody canceled!
FOR WORK WILL NEED
- air balloons
- empty bottle, preferably 1 or 1.5 liter
- tea spoon
- table vinegar
- baking soda
- Pour into the bottle vinegar by about a third.
- Pour 2-3 tsp into the ball through the funnel. soda.
Put the ball on the neck of the bottle. As a result of the interaction of soda and vinegar, carbon dioxide is released, which is known to be heavier than air. The ball filled with carbon dioxide will not be able to rise up.
To make the balloon stick to the ceiling, rub it on any synthetic material and then "glue" it to the ceiling. Thanks to static electricity the ball will hold in this position for up to 5 hours.
