As the balloon rises, the gas inside the balloon expands because the atmospheric pressure surrounding the balloon drops. The atmosphere is 100 to 200 times less dense at the float altitudes than on the ground. A balloon that is fully inflated on the ground will also have way too much lifting force.

The pressure inside the hot air balloon is affected by temperature. As the molecules heat up, they move faster and strike the inside wall of the balloon harder. This increased motion of the gas particles increases the force on an area of the balloon, producing a rise in the pressure.

The pressure inside the balloon is higher than the pressure on the outside. The pressure inside the balloon is higher than the pressure on the outside. A simple and intuitive way to look at it is if you poke a hole in the balloon, the air flows out. And the direction of airflow is always from higher to lower pressure.

Thus, a one-liter balloon of helium can lift a mass of (1.18-0.164) = 1.02 g. Of course, this would include the mass of the balloon skin itself, and we are assuming that the pressure inside the balloon is not significantly greater than the surrounding pressure of 1 atm.

Blowing into a balloon is harder than just blowing into the air, because it takes higher air pressure to stretch the rubber. once the balloon is tied the stretched rubber continues to squeeze the air inside, so inner air pressure stays higher than outer air pressure.

Gas pressure is the pressure that results from collisions of gas particles with an object. Inside the balloon, the gas particles collide with the balloon’s inner walls. It is those collisions which keep the balloon inflated.

Scientific Principle: This activity demonstrates that the air inside the soda bottle expands when heated causing the air molecules to move faster and get farther apart. This is what causes the balloon to inflate. Since warm air takes up more space than the same amount of cold air it makes the balloon inflate.

The collision of these air particles with the walls creates a high-pressure environment inside the balloon relative to the atmospheric pressure around it. This is why when a balloon is released, the high-pressure air flows out of the balloon to the low-pressure air surrounding it: “Winds blow from high to low.”

You probably feel the air pressing against the wall of the balloon with even greater force. This increase in pressure is due to a decrease in volume. By squeezing the balloon, you reduce the space the gas particles can occupy.

Bang! Exploding balloons are a staple of the British birthday experience. The air in a balloon is at a higher pressure than its surroundings because the elastic tension of the balloon skin is pulling inwards. When you stick a pin in the side it creates a tiny hole.

When anything like a balloon is filled with a gas that is lighter than the air regarding its density, then the balloon will float. Since we are talking about floating balloons without helium, we would consider Hydrogen gas here to fill the balloon.

One experiment shows that the balloon reaches a relatively constant pressure of 810 mmHg until it gets close to its maximum elasticity point and then increases to 820, 830 and finally 840 mmHg when it pops.

Temperature is one of the biggest factors affecting how long your balloon will float. They are best kept at an even, comfortable room temperature. If the room is too hot, your balloon may burst. If the room is too cold, your balloon may start to droop.

– The helium gas starts to contract around the temperature of 50-45 degrees and will decrease in volume. Once the balloon is in a warmer place the balloon will coming back to its normal size.

HAIR SPRAY Hair spray on the outside of the balloon will make it last a long time but don’t touch it or it shrivels. Hairspray actually helps keep the air in longer by sealing the balloon. Keeps your balloons bright ten times longer.

Spray the balloons with a mist of any hairspray. This interesting technique will help keep the air from escaping the balloons. Once all the balloons have been blown up, you can store them in a large plastic bag until the time for the event. Doing this will help prevent the balloons from being half-deflated and droopy.

11” latex balloons generally last between 12-20 hours filled with helium, and about 2-3 days when treated with Hi-Float. Foil balloons last approx. 5-7 days. Air-filled balloons generally last for a couple of weeks, but will not float.

Standard size latex filled helium balloons stay afloat for approx 8 – 12 hours, whereas helium filled balloons float for 2-5 days. If you want your latex balloons to float longer there is a useful product that you can buy Helium Hi-Float Treatment Kit which helps the balloons float up to 25 times longer!

A – Correctly filled latex balloons will stay inflated for around 6-8 hours, whilst you can expect foil balloons to stay inflated for a few days – a common mistake is to fill latex balloons the night before, only to wake up to deflated balloons the next day.

This is true for latex balloons, but the foil balloons will definitely last for a few days. So, if we’re talking about foil helium balloons, then the answer is “yes”, they will definitely last overnight. size of the balloon (larger ones last longer) the material of the balloon (latex vs foil)

What is ULTRA HI-FLOAT? It’s a patented liquid solution that dries inside latex helium-filled balloons to form a coating that helps hold in the helium. A single squirt inside the balloon keeps it floating longer – up to 25 times longer!

Keep them in the cool place, and avoid the temperature fluctuations. Sunlight is a major problem for balloons, make sure you keep them safe from it.

It is perfectly safe to store balloons in a car overnight. As long as there is nothing which can slash or pierce the balloons they will be absolutely fine. It will have no effect on the longevity of the balloons either.

The main reason a balloon wont float is if not enough helium has been added, check the correct size of your balloons and add helium until the balloon reaches its correct size.

Helium balloons float because helium is less dense than air. Helium balloons deflate because helium atoms are small enough to slip between spaces in the balloon material. Helium balloons are Mylar and not rubber because there is less space between the molecules in Mylar, so the balloon stays inflated longer.

Inhaling helium from a balloon isn’t likely to cause major health issues or kill you, but it’s not impossible. There have been news reports of some folks, particularly young children, dying from asphyxiation after inhaling helium from a balloon.

So even if a helium balloon can wreck an engine, the likelihood that’s going to cause a plane crash is extremely slim. If you are referring to a “party balloon” the answer is yes & no. Yes it can be sucked into an engine & no it won’t stop the engine & thus cause the aircraft to crash — it won’t even hiccup.

Mass balloon releases are illegal in several states, cities, and countries. Releasing balloons and sky lanterns should be illegal everywhere, because after all, it is simply littering. US States that have laws: California, Connecticut, Florida, Tennessee and Virginia.

about 60,000 to 105,000 feet

When you release a helium balloon into the sky, it does NOT go to heaven. Releasing balloons causes suffering and death of animals, and has no place in celebratory events. Tragically, some people use balloons as a symbol of rising to heaven.
