How long do you have to breathe helium to die with a plastic bag around your neck?
You would lose consciousness almost immediately after the first breath of helium, which would cause a "sudden and precipitous fall of the oxygen level in the blood to the brain". You might try for a second breath, but would become unconscious. Death would follow in a few minutes.
This death is very similar to how people die in an aircraft when the cabin is depressurized and there is no oxygen, except they continue breathing normally. They first fall asleep, and then death follows from lack of oxygen. (There is usually 21% oxygen in the air we breathe.) This death is known as hypoxic death (hypoxia means lack of oxygen).

Can helium make people float?
No, helium is toxic to your lungs and can kill you if you breathe it long enough, or you could have severe lung damage done to you.
How long is a plastic dessert spoon?
A plastic dessert spoon is typically around 6 to 7 inches in length.
The diameter of an helium atom is 100 pico meters how many helium atoms must be placed end to end to make chain of helium atoms one centimeters long?
To calculate the number of helium atoms needed to make a chain 1 cm long, divide the length of the chain (1 cm = 10,000 pm) by the diameter of a single helium atom (100 pm). So, 10,000 pm / 100 pm = 100 helium atoms. Therefore, 100 helium atoms placed end to end would make a chain 1 cm long.
How long can a human stay on Neptune?
Not very long. Neptune is made of Hydrogen and helium. So you can't breath.
Is helium good or bad for us?
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.
Can something breathe helium?
It depends on what you mean. We can breathe helium without any ill effects as long as we get enough oxygen. However, nothing could breathe and use helium as we breathe and use oxygen because helium is inert. Unlike oxygen, which is highly reactive, helium does not participate in chemical reactions, so it could not serve an organism any purpose.
Can helium make people float?
No, helium is toxic to your lungs and can kill you if you breathe it long enough, or you could have severe lung damage done to you.
Is helium poisenous?
No however the lack of oxygen is deadly. It is unlikely that you will hurt yourself sucking the helium out of balloons, as long as you breathe oxygen in between breaths of helium. There is a small percentage of helium (.0005%) in the earths atmosphere.
How long would you have to breathe straight helium for it to kill you?
About 2 minutes, the same as you would last not breathing oxygen.

How long till plastic will run out?

around the 1950's
How long is a plastic dessert spoon?
A plastic dessert spoon is typically around 6 to 7 inches in length.
Can kittens breathe under blankets?
Yes, kittens can breathe under blankets as long as there is enough air circulation for them to breathe comfortably. It is important to ensure that the blanket is not too thick or tightly wrapped around the kitten to prevent suffocation.
Can penquins breathe underwater?
no but they can hold their breathe for long periods of time
