How little gravity would it take until you floated up and away like a helium balloon?

No matter how little gravity, as long as it is still positive, you would not float. For that, you would have to have less density than the air. With zero gravity, both we and the air would float away into space.

Is it bad to do the helium challenge?
A little helium isn't harmful, but inhaling an entire balloon-full can block oxygen to your brain, which might cause you to pass out. There has been at least one death from breathing helium from a pressurized tank instead of a balloon, too.
What is the difference between a full and an empty balloon?
A full balloon contains more gas than an empty balloon (even an empty balloon contains a little air). Therefore a full balloon is heavier than an empty balloon (assuming the balloons are the same weight to begin with). However, if filled with a lighter-than-air gas, such as helium, the full balloon will defy gravity due to its increased buoyancy. The only other difference is that the skin of a full balloon will be stretched and will therefore be much thinner than the skin of an empty balloon. This stretching increases the pressure upon the gas contained therein, therefore the gas is compressed inside the balloon.
Does helium affect your vocal cords?
yup it does. but there are many dangers to breathing in helium repeatedly without taking breaks for oxygen. its not the helium that's dangerous; its the fact that your not breathing oxygen. its less dangerous to just be sucking it from a balloon than a, like, giant commercial balloon or something, though. when u are just using a little party balloon, the worst case scenario is that you will become oxygen deprived and pass out. If you climb in a huge commercial balloon, then you can actually pass out, not be able to climb out b/c you are unconscious, not get oxygen and die. this really happened to some college kids in florida. not good or smart. so if you are sucking helium from a little party balloon, make sure you are taking breathes of normal air in between and don't do it for more than a minute at the most! HELIUM CAN BE DANGEROUS!!!!!!!
Will helium balloon pop on airplane?
On modern airplanes no, because the cabin is pressurised to the same atmospheric pressure as on the ground. If the balloon was on the outside of the plane, and the atmospheric pressure at that altitude were low enough, then yes, the balloon would pop.
HOW BIG A HELIUM BALLOON WOULDIT TAKE TO LIFT A 175 LBS PERSON?
Let's ignore the mass of the balloon itself and the string/rope/harness/whatever that connects it to the person. We're also going to ignore the compression of the balloon; we can assume it's mylar or something and the helium inside is at normal atmospheric pressure (if the balloon is compressing the helium, it will need to be bigger, since the density of the helium goes up as the pressure increases).At around room temperature and ordinary pressures, helium has a density of about 0.164 kilograms per cubic meter. Under the same conditions, air has a density of a little under 1.2 kilograms per cubic meter. For a ballpark estimate, therefore, we can say that a balloon with a volume of 1 cubic meter will lift roughly 1 kilogram, which makes the calculation easy: to lift a 175 lb (80 kg) person, you need an 80 cubic meter balloon, which if spherical would have a radius of 2.67 meters or a little over 8 feet 9 inches.A helium balloon 18 feet across should be sufficient to lift 175 pounds. Now you know why blimps are HUGE.
How is the helium in the tank different from the helium in the balloon?
Helium balloons are usually mylar, a metal-coated plastic film while blow-up balloons are usually latex. Helium balloons are usually filled with helium of a decent purity, while blow-up balloons basically have the same gas mixture as the atmosphere around us. A little less oxygen and a little higher humidity if inflated by humans, exactly the same if inflated by a pump. Helium balloons will fly or float in the air, while blow-up balloons won't.
How do you make a balloon filled with air fly straight?
Put a straw in the end of it and blow into the balloon. That should make it fly straight although make sure you don't use helium and make sure there is as little of wind around as possible. From Matthew
What is helium made from?
Do you mean helium? Helium is an element, so it's made of .... helium!
How much does a helium balloon weigh on the moon?
A 30cm balloon (fairly standard party balloon) holds about 8 liters of helium at 1 atmosphere and weighs itself around 3 grams (latex) on earth. 8 Liters of Helium would weigh about 1.4 grams at 1g. So a balloon would weigh in at 3 grams plus 1.4 grams times .16 (the gravity on the surface of the moon) or .7grams. Of course, the whole experiment would be moot since lacking an atmosphere, your balloon would very instantly expand and burst once you exposed it to hard vacuum. But assuming your party balloon was made of some very SUPER latex, well then... there you go. Alas, note also that even the super latex wouldn't help to make it fun, since, lacking any atmosphere to be bouyant in, even your very very light balloon would still drop like a rock at a little bit over five feet per second per second just like everything else on that airless world.
What are ALL the chemicals from the periodic table that make a hot air balloon rise?
That would be little old Helium. Hydrogen makes baloons rise even faster, but has the unfortunate disadvantage of blowing up.
What happens if their is too little helium in the air?
Helium is not important for living beings.
How do you make balloon on little alchemy?
no
