High school welding class.

Teacher was an alcoholic and would go out to his car everyday at 6th period for a drink. At that time is when all hell broke loose, chinese throwing stars flying everywhere, bombs made out of pint milk cartons and filled with oxy-acetylene as load as m-80s.

Welding partner gets the bright idea to fill the cinder block wall full of oxy-acetylene welding gas where there is a hammer hole in the wall.

Full blast for several minutes.

When he lit it, it exploded a hole in the wall 8 feet in diameter and I mean it was a very load explosion. I was knocked to the ground with concrete block pieces as well as my partner and we were both bleeding. Talk about shock wave.

The explosion startled a couple of guys working on a lawn mower engine out side where the main oxygen/Acetylene bulk tanks are stored. The explosion made them drop the lawn mower and gas leaked under the main bulk storage tanks and instantly caught fire because of a spark from the steal of the mower on the concrete when they dropped it.

Now we have a very serious situation.

Everyone is panicing. I grabbed the fire extinguisher and got the fire out from under the bulk tanks in time. Thats actually what saved my ass from most of the trouble.

The entire school heard the explosion as well as some of the surrounding community residences.

My partner took off running right through the hole in the wall. lol.

Within minutes half the school was gathered, police, fire department then then the news stations. Not good.

Although I didnt fill the wall with gas or light it. I still had some responsiblity to my partner that I didnt use. So partially my fault, but I was commended by the fire dept for getting the fire out from under the bulk tanks. That would have been a major disaster had those blown.

Id say that ranks right up there with sinking a 25ft sailboat.
