What is added to balloons and hot air balloons?
Balloons can be filled with air (don't float), or with hydrogen or helium (float because the gas is less dense). Hot air balloons use burners to heat the air so that it becomes slightly less dense than the cooler air around it, providing some lift.
What makes a balloon float?
All balloons do not float. Those that do are filled with a gas that is less dense than the surrounding air, so that is is displaced upward by weight of the denser air. Small balloons are typically filled with helium, a much lighter gas than the nitrogen and oxygen in the atmosphere. Larger balloons may be filled with heated air, which occupies a greater volume and is therefore "lighter" than air outside the balloon. Some dirigibles (airships) were filled with the lighter but flammable gas hydrogen. Hydrogen can be split from water and used to fill thin plastic bags, which will also rise into the air like balloons.
What floats and does not float?
A pencil floats, a human no float, a feather floats, paper floats, ice floats, keys do not float, rocks do not float, coins do not, flip flops float. Second answer: I think you meant to ask, 'What floats and then some time later starts to sink. If that is what you meant, the answer is: There are absorbent substances which float when dry, then after absorbing water while they are floating, they increase in density and then sink.
What objects in your home are filled with air?
Examples: rubber (or plastic) balls, balloons for children.
Can you fill helium balloons with normal air?
No it doesn't have helium. A hot air balloon derives it's lift from heated air, which is less dense and therefore lighter than normal air. A helium balloon derives it's lift from helium, a gas which at normal temperatures is less dense than normal air. So both fly 'lighter than air' but for different reasons.
Why does air haveweight?
Because air has weight, mass, and density objects will either sink or float in it. Some balloons will float for example.

What are some good things to write about hot air balloons?
Try looking up fun facts of hot air balloons. Learn all you can about them, history and common uses. Then you will sure find some great things to write about.
Shopping For Birthday Balloons?
Most people are familiar with birthday balloons. Rubber balloons are filled with helium or air and come in a variety of colors. Mylar balloons are most often filled with helium; they have a metallic sheen, and have a variety of designs printed on them. Rubber balloons are also called latex balloons. These balloons often do not last long, because the helium leaks out through tiny pores in the rubber. Filling the balloon with plain air will cause it to last much longer, but of course, such balloons will not float. On the other hand, you may not want your balloons to last long past the birthday celebration; random balloons floating around the house can be annoying. If you do want them to last, however, and you prefer rubber balloons, you can ask if your store has any balloons that have been treated with Hi Float. Hi Float is a substance used to coat the inside of rubber balloons to prevent the helium from leaking out. Balloons treated with Hi Float last up to 25 times longer than regular balloons. If you want to go the mylar route, you’ll have a lot of options. There are many shapes and colors available. There are many super-sized mylar balloons as well, which can be exciting to receive. Mylar balloons also last much longer than untreated rubber balloons, because there are few tiny holes for the helium to slip through. Some can even last for several weeks! Be careful with mylar balloons around power lines, however; they can conduct electricity, and balloons that come in contact with the lines are often the cause of outages. Be careful around children with any balloons, because they can be a choking hazard when they’re uninflated or have burst. In addition, resist the temptation to breathe in the helium; when you breathe in helium, you’re not breathing in air, so it’s like you’re not breathing at all. You can asphyxiate, even die. And that wouldn’t make for a very happy birthday at all.
What element is used more in making balloons?
Helium is a gas used to inflate lighter than air balloons.
DO balloons have latex in them?
Yes, balloons are made of latex. Correction: Most balloons contain latex. However, some do not as some people are allergic to latex.
What is a very light gas found in some balloons?
Helium is used in blimps and balloons. It is the second lightest element to hydrogen, which is not used because it is highly flammable.
