To test the device, tear a small piece of the paper towel off the bottle,
and put a few drops of sulfuric acid on it. The paper towel should
immediately burst into a white flame.
3.54 BOTTLED GAS EXPLOSIVES
Bottled gas, such as butane for refilling lighters, propane for propane
stoves or for bunsen burners, can be used to produce a powerful explosion. To
make such a device, all that a simple-minded anarchist would have to do would be
to take his container of bottled gas and place it above a can of Sterno or other
gelatinized fuel, and light the fuel and run. Depending on the fuel used, and
on the thickness of the fuel container, the liquid gas will boil and expand to
the point of bursting the container in about five minutes. In theory, the gas
would immediately be ignited by the burning gelatinized fuel, producing a large
fireball and explosion. Unfortunately, the bursting of the bottled gas container
often puts out the fuel, thus preventing the expanding gas from igniting. By
using a metal bucket half filled with gasoline, however, the chances of ignition
are better, since the gasoline is less likely to be extinguished. Placing the
canister of bottled gas on a bed of burning charcoal soaked in gasoline would
probably be the most effective way of securing ignition of the expanding gas,
since although the bursting of the gas container may blow out the flame of the
gasoline, the burning charcoal should immediately re-ignite it. Nitrous oxide,
hydrogen, propane, acetylene, or any other flammable gas will do nicely.
