Son, Don't Do What I'm About to Do

If stuff is dangerous, just leave it alone:

A man attempting to demonstrate the dangers of gunpowder to his son blew off one of his fingers in a blast that also injured the boy, authorities said.

At first, the explosion in the 22900 block of Calvert Street in Woodland Hills was thought to be a shooting, said Los Angeles Fire Department Capt. Tom Sammartano.

But, it was a father-son lesson gone wrong.

The father somehow ignited the gunpowder while trying to demonstrate its dangers just before 10:45 p.m. Wednesday.

Arriving police and firefighters found a window in the home blown out, and a bomb squad was called in to check for any further dangers.

Investigators say the son suffered minor face injuries and possible loss of hearing. The father lost a finger in the blast.

The story doesn't say if alcohol might have been involved.
