I know some people who accidentally blew up a gas station with a trash bag full acetylene and oxygen. It had a shop in the back where they worked on cars, they took it inside for some reason and when the soda machine kicked on KABOOM.Before everyone lost a sense of humor, the easy way was to take balloons and load them up with acetylene and oxygen. For an epic July 4th bang, instead of balloons, it was trash bags.
Yep. Judging by the dress, bike and car, looks like a Saturday “hold my Mt. Dew” neighborhood dare event from the ‘60s, with a Dad sitting on the porch drinking a beer watching the potential disaster unfold? LOL
