See-through cylinder demystifies the four-stroke process

Of all the wondrous properties possessed by the materials that comprise internal-combustion engines, transparency is not one. For many folks, what is happening inside an engine will forever remain a mystery. Much like the dilemma of a fridge and its door-activated light, how can we know for sure what's happening inside if we can't see it with our own eyes?

In the 80s, quartz bodied spark plugs were available to observe the combustion temperature to accurately adjust carburetors.

The video was fun to watch. The Warped perception video he referenced is even better.
