What is the fastest hot air balloon?
Designed to fly in the trans-oceanic jet streams, the Pacific Flyer recorded the fastest ground speed for a manned balloon at 394 km/h (245 mph).
How do you increase the speed of a balloon?
Some of the things that slow balloon cars down, that you have to overcome, are their own weight, air resistance, friction, and inefficient use of the air escaping the balloon. Reducing weight, minimizing drag, cutting friction and improving nozzle air flow will all help make your balloon car go faster.
How does mass affect a hot air balloon?
Since it has the same mass but now has a greater volume, its density (mass/volume) decreases. This means that the more you heat the air inside the balloon, the more it expands and the more escapes, leaving less mass of air inside the balloon.
Why does a balloon stay above a fan?
When the ball starts to fall off the column of air above the fan, the surrounding higher-pressure air pushes the ball back into the area of lower pressure above the fan. As a result the ball stays afloat on top of the fan.
Do balloons explode?
The most likely cause was the balloons catching fire and exploding. Gas balloons float because they are filled with a gas less dense than air. These balloons are commonly called helium balloons, which is a misnomer since helium is not flammable and a helium balloon will not explode when it comes in contact with fire.

If the membrane is too thick (i.e. like a water balloon), the mosquitoes will not be able to feed. Because of the bag material and lack of extreme internal pressure, our blood feeding bags do not explode when mosquitoes puncture them.
Can you pop a balloon with your bare hands?
Popping a balloon starts with keeping the inflated balloon in place so that you’re able to make contact with it. While it’s easiest to pop a balloon using a sharp object, you can also pop balloons just by using your own hands or feet.

Does popping a balloon hurt?

How loud is a balloon pop?
Researchers found a balloon inflated to rupture peaks at 168 decibels (dB). That’s louder than a 12 gauge shotgun which hits 165 dB and louder than thunder at 120 dB. It’s also louder than a firecracker which peaks at 140 dB, according to the Center for Hearing, Speech and Language.
What happens if a balloon pops near your ear?
Sounds louder than 85 dB can cause permanent hearing loss, according to the American Speech-Language-Hearing Association (ASHA). This means the sound of a popped balloon can cause permanent damage to children, who have tiny, more sensitive eardrums.
