    its not something i recommend you try doing. and it depends on the size of the balloon. a tiny one wont hurt you it will just make you do that squeky thing, but a few big ones probobly cant be good for you. and just as a side note, its a HELIUM balloon, not like the air we breath, helium is high up in the sky not to much down here where we breath. your body needs certain things out of the air that helium cant give you, like oxygen for one. by breathing in helium for a while instead of air, your starving your body of all the vital things in air that it needs. sorry if that little tangent sounded mean, i didnt mean it to be im just pointing the danger out

    If you were to use the Search for Questions feature at the top of the page, you would get a variety of answers, but the most common goes something like this: The skin of a latex balloon is actually porous. Normal atmospheric air, like what we breathe, cannot go through it because its molecules are too large. Helium's molecules are much smaller, small enough to seep through the tiny tunnels through the latex membrane. Thus, the helium party balloon gradually and eventually sinks down to the floor. Now there is a rubbery compound known in the balloon industry as Hi Float. This substance is injected in the balloon prior to inflating with helium, and coats the inside of the balloon to slow the seepage loss of the helium. It is not perfect, but it makes the balloon float longer than if left untreated. Covering the balloon with silicone or tin foil might delay helium seepage, but they will weigh down the balloon enough so it won't float, which defeats the purpose of putting helium in there in the first place. Besides, very messy!

    if you breathe pure helium in constantly there is a possibility of death by asphyxiation. you would have to breathe in enough helium to displace most of the oxygen in your brain. unfortunately your breathing reflex is mostly triggered by the overabundance of carbon dioxide, not lack of oxygen....so your brain wouldn't even know it's suffocating until you black out.

    your brain requires about 3.3mL of oxygen gas for each 100g of brain tissue you've got....so i guess asphyxiation just depends on how much brain exists between your ears. feeling light headed is a good sign of oxygen depletion, so don't push your luck; and unless you're a cat or you believe in reincarnation, you've only got one life just like the rest of us.

    after 2 or 3 you start to feel lightheaded...after that it is unsafe

    people have died from helium OD believe it or not

    not something to do very often

    Why would you breath a freakin balloon anyway?!?!?! OK anyway, i say about 65 if you're strong enough and 1 if you're weak!!!!!

    depending on how big it is. I would say just one normal sized balloon, that's pretty unsafe.
