Just in case anyone wants to engineer their own semi-functional bubble machine, all it takes is a fan, a coat hanger, an O-ring, some string, a cinder block, and something to strap it all together. It's one of those solid reminders that people can do literally anything they want to with their free time. But hey, it's not like we've engineered our own bubble machine, so points to this person for figuring it out.

Alright that's great.

For most of us this would be an honest mistake.
