There are a few 'secrets' to Molotov Cocktails:
a) do not use champagne bottles. I know they might look more elegant, but the glass is reinforced because of the gas in this wine, and won't break when thrown, a key part of the Molotov Experience. Use a bottle made of thin glass. Also do not use plastic bottles, as these do not break, and are not eco-friendly.
b) although the original Finnish design called for long storm matches as the ignition element, pre-soaked rags work better.
c) add a dash of laundry detergent; the cheaper the better, rather than name brands such as Daz.
And if you still get caught by pirates, follow the example of Julius Caesar.
