This Brilliant Guy Found A Way To Repaint His Car Without A Paint Gun
They say necessity is the mother of invention, and after watching this video I'd be willing to wager that the unnamed Romanian gentleman in this video would most definitely agree. After being faced with the task of repainting this car but not having the spray rig needed for the job, he puts some good ol' fashioned ingenuity to use to make his own mouth-operated version. As you can see, he actually gets some great results too!
Although it may seem a little crazy at first, the idea of a breath-powered spray gun is actually not that uncommon. Spray guns come in several varieties, one of which is the siphon gun. According to Bernoulli's Principle, if air is blown through a horizontal tube, it creates a siphoning effect on liquid and draws it up into a vertical tube and then outwards into a spray. Normally, this process is motorized, which also helps create a smoother, more even flow, but this guy definitely doesn't seem to have any such problem.
