Why is it so loud when a balloon pops?

The air in a balloon is at a higher pressure than its surroundings because the elastic tension of the balloon skin is pulling inwards. The high-pressure air that was inside the balloon is now free to expand and this creates a pressure wave that our ears hear as a bang.

Do helium balloons pop loudly?

If your balloons popped & you need more helium, get a free quote from us. As the high pressure inside the balloon expands outward, it creates a sudden wave of pressure. This pressure wave is what creates the loud bang that we hear.

Why did my helium balloon burst?

This is because helium molecules get bigger when they heat up, so if your balloons keep getting hotter, they will eventually pop.

How loud are balloon pops?

A study, published in the Canadian Audiologist journal, found that when a balloon is tightly inflated to pop, the bursting balloon is louder than a shotgun going off next to someone’s ear and nearly as intense as a 357 magnum pistol. Researchers found a balloon inflated to rupture peaks at 168 decibels (dB).

How loud can a balloon pop?

As expected, the worst-case scenario was when a balloon was inflated to rupture at the entrance to the microphone. This would be the equivalent of a person blowing a balloon to rupture right beside another person’s ear. Mean peak SPL in this scenario was 167.82 dB with a standard deviation of 3.75 dB.

Is it OK to leave helium balloons in car overnight?

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.

Can helium explode with heat?

It is not explosive either. You can heat it up or cool it until it turns to a liquid (at below absolute zero) and it still won’t catch fire. Helium is one of the most stable elements, which means that it is not very reactive with other elements. It is a noble gas.

Is it safe to swallow helium?

Science says that when you inhale helium, it displaces the oxygen already present in your body. That means that when you do inhale it, you are only inhaling helium; there is no oxygen. While a little bit is harmless, when you take in a lot of it, it can be dangerous.

Can helium tanks explode?

Helium tanks cannot explode. The reason is because the cylinders are equipped with an approved burst disc. In case of any unforeseen circumstances, such as a fire, the cylinder will release gas in a controlled manner and will not explode. Therefore, a helium tank can be used and stored at home.
