What happens when you release balloons into the sky?

During holidays, festivals, anniversaries. people often release lots of balloons into the sky, making them look beautiful and fun. However, few people ask the question, where do balloons go after flying into the sky? Most people probably won't care or notice, just see them fly into the sky and disappear.

Release balloons into the sky.

Balloons are often filled with Helium gas. Helium is a lighter gas than air, so the balloon will fly high, just like when we drop a piece of wood into water, the piece of wood will float, even if Press down and the piece of wood will float up on its own. The higher you go, the thinner the air becomes, the atmospheric pressure decreases, so the balloon expands more and more. Depending on the durability and toughness of the rubber, when it reaches a certain height, the ball will break and fall to the ground.

If the material used to make the ball is good, the ball can fly up to about 10km high. At this altitude the air is very cold, causing the rubber to lose its elasticity. The pressure inside the ball will cause the ball to break into many small pieces, which can fall to the ground or fly very far into dust in the air.

Depending on the material and durability of the balloon, the balloon can fly from 400m to about 11km before breaking and falling. This will pollute the environment.

A bird ate a balloon because it mistook it for food.

The biggest risk of balls falling to the ground is causing environmental pollution. Animals on land and water can mistake it for food and eat it, causing harm to natural animals. In addition, releasing balloons can cause unsafety to the aviation industry or balloons flying into power lines can cause fires, explosions, and electrical shorts.

In addition, releasing a large number of balloons is also wasteful and expensive , especially helium gas is lost in a very wasteful way. That's why we should consider using balloons in festivals.
