This Instructable will cover the steps necessary to safely make an alcohol lamp from easily obtainable materials. It can be used to create a sterile space for microbiological experimentation at home, e.g. to culture yeast from a bottle of unfiltered/unpasteurized beer.
Safety is the # 1 priority when working with flammable materials. You and you alone are responsible for your own safety and the safety of those around you, especially when you are working with flammable liquids and fire. Work in an area free of flammable objects (e.g. the can of fuel) and always work with a fire extinguisher nearby. Be smart. Don’t burn your house or apartment complex down. Never leave a lit alcohol lamp unattended.
