Method How to go about H2S without a car?

[ZeroSuitDoomgirl]

As mentioned, I have the necessary stuff for an H2S method to work, but it is often recommended to use this method in an enclosed space like a car, which I don't have access to. An alternative plan I had would be to sort of combine this method with an exit bag sort of method, with a bag over my head to trap the H2S fumes and achieve the required concentration. Would this work with just a trash bag if I was in a poorly ventilated room, or would I need to create a proper exit bag setup to ensure that this would work? I do realize that the pros of an exit bag are so that one can use a gas like nitrogen that gives a more peaceful end than H2S, but my budget is extremely tight right now and I really only have a week or so to get this settled.

Whatever you do you must not leave behind an environment that could be potentially hazardous to people who come to the death scene.

Of course, I'll leave warning signs up outside my bathroom door, and seal the cracks off with putty or something.
