Will balloons pop in a hot car?
Please don't leave balloons in a hot car – helium expands in the heat and this could cause your balloons to pop! We recommend that you use air conditioning in your vehicle when transporting balloons on a hot day. If your balloons get rained on and start to droop, don't worry – they'll float again when dry.
Helium balloons may burst if exposed to temperatures higher than 100 degrees Fahrenheit. At this temperature, the helium inside the balloon expands and puts too much pressure on the material of the balloon. Check out some ways to make the Party City's foil helium balloons last longer here.
The best balloon decorations for summer would be balloons of lighter colors, preferably white. Light colors reflect more sunlight and heat than they absorb, and as a result, they last longer. Choosing darker balloons is a bad idea. The darker the color, the more heat it'll absorb and the less long it'll last.
Helium does not like the cold so leaving it in a garage or a car overnight will reduce the life of the balloon dramatically. Keeping it at room temperature will always ensure it looks it's best for the longest period of time.
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 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.
When the temperature rises, the air or helium within the balloon expands. Similar to overinflation, this increases the pressure on the balloon skin until it eventually pops. That's why you should always underinflate balloons when working in warm or hot outdoor conditions.
It is my experience that in 80 degree temperatures balloons expand. Also, 80 degree weather calls for 16″ balloons sized down to 12″ so there is expansion room in the heat. They should stay up all day. However, I warn customers not to expect latex to last more than one day outside in the heat.
- Place them in a plastic bag. Instead of letting the balloons drift hither and thither, slide all of them into a large garbage bag that's turned upside down. ...
- Put them in the back seat. ...
- Tie them down. ...
- Run the air conditioning on a low setting. ...
- Don't let go!
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.
Does heat affect air blown balloons?
If you are working with helium-filled balloons, keep in mind that extreme heat speeds up the balloon diffusion process. So, in high temperatures, helium will escape much faster than normal, drastically reducing float time. Using larger balloons and more helium may mitigate these effects.
You need to be aware that; Balloons will swell/ expand in the heat. Darker balloon colours will absorb heat and pop faster. Balloons will oxidise and lose their clarity.

Cooler temperature shrinks the volume of the balloons because colder temperature removes energy from each helium molecule. So, if you are wondering if helium balloons would pop in the cold, the answer is: no, it would do just the opposite, it would shrink.
Air expands when heated and increases the pressure in a closed space, causing the balloon to inflate. When the heat is removed, air molecules contract and take up less space, causing the balloon to collapse.
Put Them in the Backseat
The back seat is the best option to stash your balloons. Putting them in the trunk of your car may result t overheating of the balloons hence making them explode. Putting them in the front seat may bock your view while driving.
Do air balloons last overnight? Generally speaking, yes. Air-filled latex or foil balloons will not deflate overnight, especially when the arch, column or garland is indoors. Even an outdoor arch or column will last overnight.
DuraBalloons are the world's strongest balloon. No matter what the climate has to throw at it, the DuraBalloon will stay inflated.
If you're inflating balloons yourself, good news is you can save your lungpower by using a handheld balloon pump or an electric balloon bump. In general, most air-filled balloons will last for 6-8 weeks.
With Hi-Float sealant, helium-filled latex balloons have a float time of up to 18 hours indoors. When ordering latex balloons, you should always request delivery on the day of the party. Foil balloons can remain afloat for several weeks, so they can be delivered a few days prior to your event.
Helium is sensitive to temperature changes. Cold air causes the helium to shrink, which makes the balloon appear to deflate, although it still floats. Heat can cause the helium to expand and the balloon to burst.
Does Hairspray keep balloons from deflating?
Using hair spray for balloons is sometimes recommended as a way to keep them from deflating too quickly, but this strategy won't have much of an effect on the appearance of the latex itself. Once balloons have oxidized, you're probably not going to make them look as shiny as when they were first inflated.
The balloon can only rise up until the atmosphere surrounding it has the same weight as the helium in the balloon. This happens at about a height of 20 miles (32 kilometers) above Earth's surface.
A standard balloon arch made with properly inflated latex balloons will last anywhere from 12 hours to 2 days without any significant issues. The lower number represents an arch closer to a doorway where outside heat and humidity are being introduced regularly.
Balloons fly best in light and stable winds of 4-6 miles per hour. Maximum safe winds are 8-10 mph. Wind affects every phase of a flight.
NOTE: Helium expands in the heat. Warm or hot temperatures can bring balloons down faster than their proper float time and may result in popping. Wind is another weather factor to look out for.
You would expect the helium balloon to travel to the back of the car as well. The problem is that the helium inside the balloon is less dense than the air surrounding the balloon. The balloon tries to 'float' above the dense air in the back of the car, causing it to go forward.
You can usually fit about 30 balloons into the back seat of a standard sedan car, or 50-60 into a small hatchback with the back-seat laid flat. Allow a little less room for bouquets as they take up more "air-space" when in their transport bags.
In warm weather, latex balloons will typically only last outside for a day. As you know, sun, wind and heat will biodegrade the latex. With that said, however, there are tricks you can do to raise your odds of getting them to last more than a day outside.
Generally speaking, yes, your helium balloons will last overnight, but they may not last long enough to have an event the next day. This is true for latex balloons, but the foil balloons will definitely last for a few days.
The balloon when kept in sun gets heated and the air inside it also gets heated. The molecules of air get energy, and vibrate faster thereby exerting large force on the walls of the balloon. Due to this expansion of gases the balloon bursts.
Are balloons better in hot or cold?
Balloons & Temperature
When helium-filled balloons are taken into the cold, they will temporarily deflate and will re-inflate again when warm. Please store in a cool room balloons are best kept at room temperature.
Weather and humidity are two important conditions to consider. In low-humidity weather (such as winter), float life will be longest. Typically, treated balloons float only one-fourth as long in summer as they do in winter because of higher heat and humidity.
Foil and latex balloons can be kept in their transport bags until they are required unless your latex balloons have been treated with Hi Float.
Always place the balloons in the back seat of your car. We do not recommend placing the balloons in the passenger seat as this can interfere with your driving. Also, just before take off, maximise the vehicle's air conditioner to keep the air cool.
And when it's really hot out, the heat needed to take off and fly can even damage the balloon. “We start to cancel flights if we believe it's going to be 95 degrees or hotter at flight time,” Jones says.
The balloon has air filled in it. The balloon when kept in sun gets heated and the air inside it also gets heated. The molecules of air get energy, and vibrate faster thereby exerting large force on the walls of the balloon. Due to this expansion of gases the balloon bursts.
Initially, the balloon will absorb energy from the oven and increase its own internal energy thereby raising its own temperature. Moreover, it will expand against the atmosphere thereby increasing its own volume. The temperature of the balloon will rise until it equals the temperature of the oven.
Group stringed balloons together and tie them to a weighted object. You can use a hand weight, can, water bottle for tying down. This will prevent the balloons from flying away. If the balloons do not have string, place them inside of large trash bags.
In a typical saloon car (4 doors and no passengers) will probably fit about 20-30 balloons. A station wagon (no passengers) will probably take about 50 balloons.
This is because helium molecules get bigger when they heat up, so if your balloons keep getting hotter, they will eventually pop. If you do need to leave balloons in a car on a hot day, it is best to put them in the trunk away from direct sunlight.
Is helium tank okay in hot car?
Q: Is the Helium Balloon Cylinder safe to transport in the car? A: That is a really good question. Our Helium Balloon Cylinder contains Helium; a non-flammable, non-toxic, compressed gas that is generally safe to transport in a car.
You can usually fit about 30 balloons into the back seat of a standard sedan car, or 50-60 into a small hatchback with the back-seat laid flat. Allow a little less room for bouquets as they take up more "air-space" when in their transport bags.

Put Them in the Backseat
The back seat is the best option to stash your balloons. Putting them in the trunk of your car may result t overheating of the balloons hence making them explode. Putting them in the front seat may bock your view while driving.
Though it's safe to transport a helium gas canister, one should never be left in a vehicle for longer than is necessary. Unload the canister as soon as you get to your destination, and make sure to never store a canister in a vehicle for any period of time – particularly in direct sunlight, or unattended.
Always place the balloons in the back seat of your car. We do not recommend placing the balloons in the passenger seat as this can interfere with your driving. Also, just before take off, maximise the vehicle's air conditioner to keep the air cool.
