A clear engine lets you see the magic inside your car
That project would be cool on its own, but these mechanical sorcerers also built a transparent engine, so we can finally see with our very eyes what happens inside a combustion chamber. That engine is also a Briggs and Stratton, but running on propane, and they had to do some fancy mechanical maneuvers to get a transparent roof over the valves so we can see inside. They moved the spark plug from its usual position atop the head, and replaced the ignition coil with a Model T-style trembler.
Take one transparent engine, add slow-motion
The final product is cool on its own, but then Sandlin shot it with a high-speed camera. That’s where the fun and amazement begin. Prepare to be awed.
