How do you inflate a balloon science project?

Instructions

Using a funnel, pour about a third of a cup of vinegar into the bottle.
Then insert another funnel into the mouth of the balloon.
Place two teaspoons of baking soda into the funnel so it falls into the balloon.
Next, secure the the mouth of the balloon over the top of the bottle.

What gas do you use to inflate a balloon experiment?

carbon dioxide gas
The Science Behind It Vinegar (our liquid) is an acid and baking soda (our solid) is a base, and when they combine the product they create is CO2 or carbon dioxide gas. The carbon dioxide gas inflates the balloon because it has nowhere else to go!

What makes the balloon inflate in the activity?

Warm air is less dense than cold. Since warm air takes up more space than the same amount of cold air it makes the balloon inflate.

What does self-inflating balloon mean?

Self-Inflating Balloons contain two chemicals that are kept from reacting until the balloon is activated by hitting it. Interestingly, the balloon also cools as a result of an endothermic process that results when the baking soda dissolves in the liquid water from the inner plastic bag.

What is inside a balloon?

A balloon can be defined as an inflatable flexible bag filled with a gas, such as helium, hydrogen, nitrous oxide, oxygen, or air. Modern balloons are made from materials such as rubber, latex, polychloroprene, metalized plastic or a nylon fabric. Long before there was something as stretchy as rubber, balloons existed.

What do you fill into a balloon?

Blowing up a balloon requires forcing additional air particles from our lungs into the balloon. These particles bumped the balloon’s inside walls, creating enough air pressure to force the rubber of the balloon to expand and the balloon to inflate.

How do you inflate a balloon with a valve?

Instructions There is a small valve or opening in the “tail” of the balloon. Slide this opening onto the nozzle of the helium tank or balloon pump until you have a tight fit. Hold the neck of the balloon firmly around the nozzle with one hand and press on the nozzle to release the helium into your balloon.

Can baking soda inflate a balloon?

Inflating the Balloon Pour a little vinegar into a plastic bottle. Use a funnel or straw to put a little baking soda into a limp balloon. Stretch the neck of the balloon over the top of the bottle. Lift the balloon up over the bottle and watch the reaction. Try again with more vinegar or baking soda, if it doesn’t work the first time.

How long does an air filled balloon stay inflated?

Air-filled balloons can retain air for much longer, often remaining inflated for weeks or months. Size plays a major role in the inflation time of a balloon. A 16-inch helium-filled latex balloon can remain filled for up to 30 hours, while a 9-inch balloon can stay afloat for approximately 8 hours.

What makes a balloon inflate?

With more air molecules in the balloon, the pressure inside the balloon increases. The balloon inflates to increase its surface area so that the force acting by the air molecules inside outward = the force acting by the air molecules outside inward.

Why does the balloon inflate into the bottle?

This is because the high pressure air in the balloon pushes outward harder than the low pressure air in the bottle. The air in the balloon pushes out against the walls, keeping it inflated. When the hole is unplugged, air flows back into the bottle. The air pressure in the bottle increases and collapses the balloon.
