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 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 you use methane to fill balloon?
It is possible to use methane to fill balloons. However, Methane has poor lifting capacity and has other safety defects and has never been widely used. Refer to links below for more information.The hot air balloon obtains its buoyancy by heating the air inside the balloon. It has become the most common type.The gas balloon is inflated with a gas of lower molecular weight than the ambient atmosphere. Most gas balloons operate with the internal pressure of the gas the same as the pressure of the surrounding atmosphere.Gas balloons are usually filled with gases such as: hydrogen - originally used extensively but since the Hindenburg disaster is now seldom used due to its high flammability.helium - used today for all airships and most manned gas balloons.
Do balloons have the same charge?
no
What would happen if you put two positively charged balloons together?
You then have two balloons in very nearly the same place.
Can same type of balloons withstand the same amount of pressure?
Yes, no matter how much air is filled inside of the balloons.

Yes, most party stores will supply balloons for the same day delivery. However, they may charge more.

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.
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.
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.
When you rub two balloons with wool and gets static do they attract?
If you rub two identical balloons with the same thing, then they both have the same sign of charge, and like charges repel.
Where did the first air balloon take off?
As early the 200s AD, Kongming lanterns, (which essentially were miniature lantern/hot air balloons) were used in China for military signaling. However, the first manned hot air balloon flight (which was tethered to the ground), was done by Joseph-Michel and Jacques-Etienne Montgolfier in Annonay, France on October 19, 1783. The first untethered hot air balloon flight was done by the same brothers, in the same town, on November 21 of the same year.
Are water balloons regular balloons?
No, because a water balloons pop when they hit a hard surface where as a normal if you fill it with water then it will not pop when it hits a hard surface as it is not made from the same latex its made from a more fragile material.
