This is one of the most popular methods but it has be subject to debates regarding the success of the method. You will be needing a cylinder of Helium, control kit and hose for regulating the flow of the gas, a big plastic bag and any elastic material like rubber band or something like that which can hold the plastic bag in place. Here is how it works:
- Fix the control kit and hose with the cylinder of Helium.
- Put the other end of the hose inside the plastic bag and fill it with Helium.
- Insert your head inside the plastic bag and use the elastic object to fix the plastic bag with your neck. Don't forget to keep the hose inside the bag for steady supply of Helium.
Now what? Take two or three (or as many as you can) deep breaths. Since there is no oxygen in the plastic bag and since the air that you breathe out has no oxygen as well, you become unconscious pretty soon. The steady supply of Helium through the hose will ensure that you die within 10-15 minutes.
Some Important Points:
- Instead of Helium, you can use Chlorine (which will have an unpleasant smell), Nitrogen, Argon and other gasses which are pretty easy to acquire. You can buy Helium Cylinders from eBay or Amazon.
- Make sure that the elastic band you are using is strong enough to hold the plastic bag in place.
