Helium filled balloons stop floating because the helium leaks out. The balloon latex is porous and the helium is a very small atom and leaks out causing the balloon to lower and eventually stop floating.

How does helium behave?
helium behaves by helping to blow thing up nd lainch things
A lighted splint is put into a gas jar of helium . what would happen?
the lighted splint would stop burning as Helium does not burn.
What happens when a lighted splint is put unto a glass jar of helium?
The glow of the splint is extinguished, because helium can not support the combustion reaction with oxygen from the atmosphere that produces the glow.
Is helium poisonous if you inhale too much?
Yes, a single deep breath of pure helium will drive all the oxygen out of your lungs and you will pass out. After that you will probably be breathing air again so you will recover, but remember, the first result of reduced oxygen to the brain is brain damage.yes and no.............Inhaling Helium in small amounts is safe enough, such as taking a breath of helium from a balloon to change your voice, but even doing this too many times in a row can cause headaches, disorientation or lightheadedness, since helium deprives your body of oxygen...and taking a single deep breath of pure helium can also lead to unconsciousness, and maybe death by asphyxiation.Remember, the first result of reduced oxygen to the brain is brain damage. The second result is death.But other than that and the voice changes helium is basically harmless in small amounts...Helium is also mixed with other gases such as oxygen, compressed air etc for diving purposes...No. Just breath every once and a while. There is helium in the air we breathe and we're just fine. So after everytime you suck down some helium from a balloon or whatever, just take a deep breath so your brain gets the oxygen it needs.Yes, your inner organs will collapse and then blood will stop rushing to your brain any you will die in a matter of hours.you're supposed to be breathing oxygen instead, so if you breathe too much helium, you won't get enough oxygenyes.Yes. It kills brain cells and it's to high of a concentration for your body to handle. People were made for oxygen.... not helium. It also leads to brain damage. ------------------------Breathing in too much helium can displace oxygen that you need and you may get dizzy while you're doing it.If you breathe in just PURE helium, that can lead to suffocation, because our bodies need oxygen.Inhaling continuous breaths of helium one after another starves the body of oxygen. A person will eventually pass out, and perhaps even worse. At most, inhaling once or twice from a helium balloon, separated by deep inhalations of air, will be a way to prevent the harm. So, bottom line is that it's okay to inhale a bit of helium for fun but you have to pay attention to how much you inhale so it won't harm your health.- Edited answer by Omg848, 2:18 PM PST, Sunday, August 23, 2009Yes, breathing helium is harmful if that's all you're breathing. You need oxygen to live, and without O2 in the gas you breathe, you will lose consciousness and you can asphyxiate. Asphyxiation leads to death. Helium is used in what is called mixed gas breathing apparatus for use in deep diving. In this situation, the gas mixture is almost all helium, and oxygen is regulated in a way that the partial pressure of oxygen is "correct" and the diver gets enough but not too much O2 and can dive safely.It isn't a bad thing to do....we had helium balloons sink then i sucked the helium out....make sure to suck in oxygen also, or else you will probably die or something. Helium makes your voice sound weird and awesome!! I love it but it isn't that good for me. It's fun, but it's not the best. Don't do it that often. I'd use helium balloons if I were you, not helium tanks. (:
Why Balloon filled with helium does not raise indefinitely?
If you blow up a balloon then the helium inside it will run out after about 2 days. After those two days (maybe 3) there will be no helium left, but you will find that the balloon is still up and rounded but not as big as before. This is because the helium had got warm inside the balloon and transfered into a liguid, then that got evaporated and turned to a gas. Therefore the gas isn't helium. Because as it changed to a liquid, the liquid picked up other parts of gas and that transfered to a liquid with it to. So it is just an ordinary gas, Oxygen. Thank You. Lucie
Why do people use helium in balloons?
Helium is less dense than air so if you fill a balloon with it, it floats. This is helpful as it means they don't have to be hung from something. For example, many balloon arrangements you see at parties on tables or in the corner of the room are filled with helium. They sort of stand upright, in a way. However they do need a weight of some sort to stop them floating away! :)

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.
If you are 12 years old and are 5'5 can you shrink if so how?
you can't shrink you can only stop growing .
Do breast shrink if you stop using breast enhancment creams?
Breasts neither grow or shrink.
Does marijuana shrink tumors?
Science has proven that THC, in marijuana, has proven to slow/stop the growth of cancerous cells. So does it actually shrink the tumor? No, but it will help stop it from growing.
Does the ozone layer stop clouds floating to space?
No, it does not stop. They are bound due to gravity.
How do you stop the fan on shrink ray in poptropica?
you press the red button
How do you you stop floating in Active Worlds?
press "alt" and "Q"
Why do astronauts wear straps in the spacecraft?
To stop them floating about in the spacecraft.
How can you make youself stop growing?
You dont...till you get old then you shrink :D
