hot air
Yes, a candle can power up a hot air balloon. But you need a mini one to do the experiment. search hot air balloon experiment on Youtube for videos.
No, the Moon has no atmosphere. The hot air does not have the colder air to be lighter than! Such a balloon would work on Mars or some moons of the larger planets which have some kind of an atmosphere.
Hot Air Balloons work because of the hot air.The hot air rising stays in the balloon and carries it upward.
hot air balloons work the best in cold temperature. the reason why is because if the outside temperature is close to the temperature in the hot air balloon, it will be as if the flame isn't on. if it is cold outside, the flame makes a much bigger impact and the balloon will go up faster.

Balloon angioplasty (stents) Angioplasty is the technique of mechanically widening a narrowed or obstructed blood vessel, typically as a result of atherosclerosis. An empty and collapsed balloon on a guide wire, known as a balloon catheter, is passed into the narrowed locations and then inflated to a fixed size using water pressures some 75 to 500 times normal blood pressure (6 to 20 atmospheres). The balloon crushes the fatty deposits, opening up the blood vessel for improved flow, and the balloon is then collapsed and withdrawn.
Angioplasty is a popular method of surgery for curing blocks in the heart arteries due to plaque buildup. In this method a balloon catheter is injected into a narrow artery & later inflated to broaden the artery. Hence this method is also called balloon angioplasty.
A trocar is a medical instrument used in some medical procedures. A balloon trocar is an instrument used in balloon angioplasty.
