you would need 4 main materials:

a beer-bottle
some isopropyl alcohol
some duct-tape
a dry dish-rag

once you have these materials, you need to fill up the beer-bottle with the rubbing alcohol. this can be either isopropyl alcohol, or ethyl alcohol. if you do not have any of these, an entire large bottles worth of hand-sanitizer would work. make sure the entire bottle is filled with whichever form of alcohol you come across, and get your rag, ensure one end of the rag has good contact with the alcohol, and push enough of the rag into the bottle. then to ensure it stays in the bottle, use duct tape to tape the area around where the lid of the bottle usually would be. and make sure while taping the rag has good stability and will not wiggle out of the bottle. then once finished, you would be done. 

using the Molotov:

make sure to light the dry dish-rag on the end of the Molotov and ensure the rag has a decent-sized flame going before you throw it. make sure the flame doesn't reach the alcohol when its in your hand, otherwise it can explode in your hand, likely killing you. then, throw your Molotov at your target, and witness physics at its finest take place!!
