How do you expand a balloon?

How do you expand a balloon?


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

What causes the balloon to inflate?

Blowing up a balloon involves forcing additional air particles from your lungs into the balloon. These particles hit the inside walls of the balloon creating enough air pressure to force the rubber of the balloon to expand and the balloon to inflate.

What occupies the inflated balloon?

Gas particles exert pressure on the walls of the container in which the gas is filled. For example, when a balloon is inflated, the air inside it expands, thereby exerting pressure on the balloon walls.

Can yeast make a balloon inflate?

Yeast is a fungal microorganism that feeds on sugar and produces carbon dioxide (CO2) plus ethanol. As the yeast feeds on the sugar, it produces carbon dioxide gas. This process is known as fermentation. The trapped CO2 accumulates inside the balloon, slowly inflating it.

Will the balloon size grow bigger if more vinegar is in the bottle?

The Chemistry Explanation The size of the balloon gives an estimate of the amount of gas produced in the reaction. If you want a bigger balloon you should use more baking soda and vinegar because then more carbon dioxide gas will be produced.

Can you fill a balloon with hot air?

When you stretch the balloon over the opening of the bottle, all of the air is trapped inside. Putting the bottle in hot water causes the air molecules inside to heat up and begin taking up more space (thermal expansion), causing air to enter the balloon and inflate it.

What happens if you inflate the balloon more?

When you inflate a balloon, you’re actually putting gases, in this case mostly helium, into an elastic container. As you add more gas, the pressure inside the balloon increases, and in response, the balloon expands… As you go higher into the atmosphere, the air becomes thinner, and the atmospheric pressure drops.

What do you feel as you press the balloon?

You probably feel the air pressing against the wall of the balloon with even greater force. By squeezing the balloon, you reduce the space the gas particles can occupy. As the particles are pushed a bit closer together, they collide with more, so the pressure from the moving gas particles increases.

How long does it take for yeast to inflate a balloon?

Leave the bottle in a warm place for around twenty minutes. When you return it should have started to inflate! This is because when the yeast feeds on sugar it produces carbon dioxide, which is a gas. The carbon dioxide inflates the balloon.

Will sugar water and yeast make alcohol?

When a sugar wash comes into contact with a strain of yeast, over time the yeast will start to feed off the sugars and grow. As it grows, the sugars will convert into ethanol and carbon dioxide.

What happens if you put vinegar and baking soda in a balloon?

a. When baking soda and vinegar are mixed together, it creates a gas called carbon dioxide. The gas begins to expand in the bottle and starts to inflate the balloon. The more gas that is created, the larger the balloon will inflate.

How can you make a balloon float without helium?

First, fill the water bottle about 1/3 of the way full with white vinegar. Next, put baking soda into the un-inflated balloon, filling it about halfway. Ideally, you’d have a funnel handy for this process but, because I didn’t have one, I made one out of construction paper rolled up, and tape. It did the trick!

How do you fill a balloon with hot air?

Instruct one or two crew member(s) to hold the mouth of the envelope open while another turns on the fan on. Direct the flow of the cold air into the bottom of the balloon. As the balloon fills with air, crew members will not have to hold the envelope open any more as the envelope will stay open on its own.

Can a balloon cause a plane crash?

We called the FAA when we had launched small balloons. The answer is yes if you’re referring to a party balloon. It will cause the aircraft to crash if it is sucked into an engine, it won’t stop the engine, and it won’t even hiccup.

Why does balloon burst if you keep on blowing?

➡a balloon bursts when you keep blowing because the ballon has a certain capacity to withstand pressure when pressure exerted is more than it tends to inflate more than its capacity that is beyond what it can therefore at last it bursts as it can not handle that pressure.

Can you press the balloon with your hand?

When you inflate a balloon, the air pressure inside it is much more than the atmospheric pressure outside of it. Now inflate a balloon to its maximum capacity but instead of closing the opening with a knot, just hold its mouth between your thumb and forefinger preventing the air from escaping.

What happens when you release your hand after squeezing the balloon?

When you released the blown balloon, the potential energy is converted into kinetic energy, which is energy in motion. The air came out with some force from the balloon’s mouth towards you.

How do you measure CO2 in a balloon?

Now, take the full balloon, put it under water so that the opening is directly under / in the bottom of the graduated cylinder. Release the balloon, and the CO2 will rise to the top of the graduated cylinder, displacing a volume. Measure the volume of the gas, and there you have it.
