Seems like you know something on the subject so why the idiotic comment at the beginning? I still vote that you were drunk.
An original primer was fulminate of mercury. You can watch Breaking Bad to see how it was put to use. In a vented area desolve a small amount of mercury in nitric acid. The gas coming off the mix could be fatal hence the ventilation. Add a larger amount of ethanol to the mixture. (Considering some of the people here I won't give measurements but you can always look them up) The solution will heat up and crystals will start to form. Continue to add water to clean the crystals. They are highly explosive from friction, heat, or concussion. Enjoy yourself and hopefully no one else is around when you make a mistake.
