Both latex and foil balloons are porous which allows the helium to escape from the balloons. Latex balloons are more porous and let the helium escape more quickly than the foil balloons

Air filled latex balloons do not tend to deflate as the particles in air are larger than those in helium, there for last longer inside the balloon. An air filled latex balloon will stay inflated for many months without deflating. See similar questions...

No. The helium filled latex balloon is contained inside a sealed helium environment (the Sparklet). Helium inflated balloons in a helium environment will last as long as air filled balloons last in an air environment. Generally round latex balloons last as long as the Sparklet lasts (3 - 5 weeks). Hearts last for 3 weeks (inflate them nice and full to get a full "heart" shape). 350's last for 2 weeks and 260's last for 1 week. See similar questions...

In theory a balloon will deflate more quickly in a cold room as the helium contracts in the cold making it easier for the particles to escape from the balloon. In a hot room the helium particles expand making them less likley to escape from the balloon. Depending on how hot the room is, if the particles expand a lot then this can cause the balloon to pop.

Helium balloons deflate quicker than air filled balloons because the helium particles are smaller than air particles and so escape through the balloons more easily See similar questions...

No. We hardly ever deflate, unless there is an emergency. Normally, the envelope lasts up to 10 years and during that time we continually check and purify the helium levels and the pressure. Occasionally we "top up" the helium if there is some leakage during the year. See similar questions...

Balloons have been around for centuries.  The modern latex balloon that we are familiar with was invented in New England during the Great Depression. A chemical engineer named Neil Tillotson was attempting to make inner tubes using liquid latex, which was a new product.  He was having no luck.  In his frustration is cut out a cat's head and dipped it in the latex.  When it dried he found that he had a cat head.

When most people refer to a "balloon" they are actually referring to the part of the balloon known as the envelope. Balloon envelopes are typically made of rip-stock nylon or polyester fabric. The fabric of the envelope is sewn to or around a tape or rope that will bear the load placed on the envelope by the basket and its contents. See similar questions...

Hot air balloons operate on the basic principles of gravity and heat transfer. The propane burners warm the air inside the balloon envelope to as much as 250 degrees F, thus allowing the pilot to take the balloon up to whatever altitude he or she desires. Gravity pulls us back to earth as the temperature cools down. Of course the pilot can continue heating the air to prolong the flight or to control the rate of descent. See similar questions...

One of the most popular ways of advertising with our balloons is to either create a banner with your company logo or message of your choice to fit our balloon, this banner can be placed on the side of the envelope or basket. The other frequently used technique for advertisers using hot air balloons is to set up a tethered flight right outside your location or event so that people are drawn to the location out of the sheer amusement of watching the balloon.

Yes. Ultralight hot air balloons are quite feasible though they are uncommon. In the USA they are considered to be _unpowered_ ultralights (like hang gliders) and must weight less than 155 lbs. Ultralight helium balloons are also possible but the cost to fill the balloon would be too high for most users. Several experimenters have reported excellent success with one man hot air balloons and at least on manufacturer offers kits which qualify for operation under FAR103. See similar questions...

The AHA recommends a deflation rate of 2 - 3mmHg per second. During routine measurement, the system is typically inflated to about 180mmHg and deflated to about 60mmHg to a range of 120mmHg (the actual range is determined by the patient's expected blood pressure). At a deflation rate of 2-3mmHg/sec, it should take 40 to 60 seconds to deflate the cuff correctly. See similar questions...

On average it takes about 5 minutes when inflating with a foot pump. It will obviously take longer than that the first time you setup as you will want to get familiar with the components and assembly described in the owner's manual. See similar questions...

Zip files use what is commonly called the deflate algorithm. Deflate normally uses LZSS compression with a 32K sliding window, with the output of the LZSS compressor further compressed via a pair of Huffman coders. The most comprehensible public source for the deflate algorithm is in the freely available zlib package. The zlib source and more info lives at: To learn about the details of the format, you can get a pretty coherent explanation from RFC 1951. See similar questions...

You will need a shop vac. or strong power inflator. Many marina areas have compressed air, but you will need to deflate with a power unit, sucking out the air until the product is flat. We sell a power inflator for this purpose. See similar questions...

A latex balloon is made from 100 % organic material and it is 1--% biodegradeable.  Inflation causes stress which begins the process of decomposition.  This process is accelerated by exposure to sunlight.  Even in the dark, ozone and oxygen are working against the late material.  Within hours, latex balloons begin to oxidize.  You can tell this because it gets a "frosted" look.  The latex balloon will soon begin to break apart.

Most balloonists enjoy low level flight. The typical balloon flight would be anywhere from tree level to about 3,000 feet above the ground. See similar questions...

Because weight is critical in balloon flying, the baskets are made of light materials such as wicker, fiberglass or aluminum. See similar questions...
