How do you set off a bomb?

you don't.............. its not in human nature to do so, and I'm watching you.................. whoever wants to find this out.

it is all dependent on the type and reason of the question,

what type of explosive are you asking about also what reason are you asking this for... if you just want to know how it works ask how does a _____ bomb detonate/work. think more about the question your asking.
