Why foil balloon is not deflating?

Foil balloons don't deflate as quickly as regular latex balloons for a few reasons:

Material: Foil balloons are made of thin, metallic material that is less porous than latex. This makes it harder for the helium gas to escape through the balloon's walls.

Seal: Foil balloons often have a self-sealing valve that prevents air from leaking out once the balloon is inflated.

Shape:The shape of foil balloons is often designed to hold their form better, making them less prone to deflating due to pressure changes.

Helium quality: While helium is a light gas, it's not truly "permanent." Over time, it will naturally diffuse into the surrounding air. However, the rate of diffusion is much slower in foil balloons due to the reasons mentioned above.

1.Find the inflatable port

2.Inflate the balloon with air and helium

3.Press the balloon to make sure the inflated air is not more than 75%

4.Finish the balloon

Why some foil balloons might deflate faster:

Damage:A small tear or puncture in the foil can allow helium to escape faster.

Extreme temperatures:Very high or low temperatures can affect the helium's pressure, potentially causing the balloon to deflate faster.

Exposure to sunlight:Prolonged exposure to sunlight can degrade the foil material.This makes it easier for the helium to leak out of the balloon.

In general, foil balloons can last for days or even weeks before they completely deflate. However, the exact lifespan will depend on the factors mentioned above.
