How did the mongolfier brothers make the first hot air balloon rise?
The Montgolfier brothers correctly noted that smoke always rises from a fire. However, what they failed to realize is that it is not the smoke which is rising, but the heat from the fire which rises and incidentally, carries the smoke up with it.When the Montgolfier brothers attempted to harness the lifting power of fire, they chose a fuel which would produce a large amount of smoke. Namely, wet straw. The balloon did rise and fly, but it can't have been a very pleasant experience.Modern hot air balloons fly in much the same way, but rather than using straw for fuel, propane is used as it is nearly smoke-free and is easily portable.
How balloons and blimps are able to fly in oceans of air?
Balloons float because of the same principal as how ships float: bouyancy. A ship displaces a volume of water. If the ship's weight is less than the volume of water that it displaces, then it will float. Same is true for a balloon. It displaces a volume of air. If the Hydrogen or Helium in the balloon weighs less than the volume of air it displaces, then it will rise.
Why are hot air balloons spheres?
Hot air balloons are usually shaped like an egg because it is an easy to fold and inflate shape. However there are hot air balloons shaped like cartoon characters or advertising symbols. There are people that specialize in creating unique shapes for hot air balloons.
Why is a high altitude hot air balloon only partially filled?
As it rises, outside air pressure decreases, and the hot air inside expands and fills the balloon. Same thing is true of large helium balloons.
Why do balloons float up?
This is because of the helium they use to blow them up. If you noticed if you blow it up with your mouth, it does not float. Helium is much less dense for a given volume than air. The air pushes beneath the balloon and forces it upward. If it reaches a point high in the atmosphere where the air is the same density as the helium, it will stop rising. However, the pressure in the balloon will also force it to expand, so it will normally pop before it gets that high. Most latex balloons will pop, and most Mylar balloons will split open, somewhere around 2,000 to 5,000 feet in the air.
Can same type of balloons withstand the same amount of pressure?
Yes, no matter how much air is filled inside of the balloons.
Who can do same day delivery for balloons?
Yes, most party stores will supply balloons for the same day delivery. However, they may charge more.
What would happen if you put two positively charged balloons together?
You then have two balloons in very nearly the same place.

Are all loan calculator balloons the same?
All loan calculator balloons work in the same way. If the same information is entered by the user across each calculator, then the information displayed at the end by the calculator will be the same.
Why do two balloons repel when you rub them together and they are tied together on the same string?
When you rub the balloons together, they become charged with static electricity. Since both balloons have the same charge (either positive or negative), they will repel each other due to the electrostatic force. As a result, the two balloons on the same string will push away from each other.
Who was the first person to fly a blimp?
The French Montgolfier Brothers were the first to fly a balloon, I'm not sure about a blimp. They are not the same.
When you rub two balloons with wool and gets static do they attract?
Yes, when you rub two balloons with wool and create static electricity, the balloons will become charged. As a result of this charge, the balloons will then attract each other due to the electromagnetic forces between them.
What is the answer to six groups of students sell 162 balloons at the school carnival. there are 3 students in each group if each student sells the same number of balloons how many balloons does each?
Each student sells 9 balloons.
Do the balloons have the same charges. Each balloon is pushing the other away?
The balloons likely have the same charge, causing them to repel each other due to the electrostatic force. This repulsion is a result of like charges (positive or negative) creating a force that pushes the balloons apart.
Does same type balloons withstand the same amount of pressure?
No, the ability to withstand pressure is determined by various factors such as material, design, and thickness of the balloon. Two balloons of the same type may not withstand the same amount of pressure if they differ in these characteristics.
