What you didn't know about hellium balloons

The treatment with a special compound called "hi-float" (a liquid plastic solution) creates a film inside the balloon whose pores are very small, and as a result, the helium escapes very slowly and the balloon flies for longer, about 5 days.

In ideal conditions, a treated balloon can "live" for up to a month!

Hi-float is safe for your health and the environment. If it gets on your skin, it can be washed away with plain water without any problems.

Why do helium balloons deflate?

• The main reason that the balloon flies so little is the size of the helium molecules. Helium molecules are much smaller than those of air and easily penetrate through latex from which balloons are made. Therefore, with time helium just comes out of the balloon, which deflates and falls. This is the first reason balloons fall.
• Helium is also negatively affected by sunlight and elevated temperatures. As a result, serious pressure is created in the middle of the balloon, which pushes the gas outward. Therefore, it is important to hide the balloons from direct sunlight and heating devices.
• In addition to the sun, the balls are also negatively affected by precipitation. They settle on the latex surface, thus increasing the total weight of the balloon, which begins to slowly fall. But do not worry: when the water evaporates, the balloon will be able to take off again. In a strong wind, the balloons rub against each other, wearing themselves down severely and forming microcracks through which the helium passes.
• It is also worth avoiding drafts, moisture and sudden temperature changes.
• The most common reason why helium balloons don't fly very much is mechanical damage. But there is nothing we can do about it, after all, balloons are created to be played with, run around, jump and enjoy their beauty.
• At different times of the year the time of flight of balloons with helium changes. In summer, in hot weather with considerable humidity, even very well processed balloons fly for an average of 2 days. In late fall, it's about 3 weeks. Cold and snow have no effect on the service life of helium balloons, on the contrary, prolongs it.  But do not forget that every condition created is individual.

There are many other harmful factors affecting the flight of the balloon, so it is not enough just to treat it.

Tinfoil balloons

Tinfoil balloons are more durable: their walls are denser, so they hold gas much better than latex. A sealed balloon with air can hold for several months, a helium balloon for a week or more. 

Such a balloon responds well to changes in temperature, so that in the cold it shrinks noticeably, and in the warmth it regains its shape and size. Do not store foil balloons at a higher temperature than the one at which they were inflated, in order to avoid breaking the foil at the seams.

Height of lift of helium balloons

Everyone has ever wondered how high helium balloons can rise. Such thoughts usually come when the balloon filled with gas disappears from view behind the clouds and no trace is left of it. Helium is lighter than air, which ensures the balloon's flight, but the sphere will not fly further than five kilometers from the ground.

This is because there is a huge difference between the pressure inside the balloon and the environment. At a high altitude, the air is rarefied, so the balloon expands and eventually bursts.
