That's what you do. Take glass jar. Some water.. Mark the water level on the jar. Add suspect gas and shake. If the level of the water rises then you know ethonal was in the gas. They make graduated jars for this purpose that will tell you the percentage of ethonal in the gas.I think if you put some in a glass jar and add water. Shake it up and it will draw out the ethanol if you end up with more watery looking stuff than you added it's got alcohol in it.
