We've seen a lot of recently, but this latest trend is, well, just watch. A bunch of Lego builders on YouTube are building complex engines, and hooking them up to electric motors with the sole purpose of spinning them to destruction. These videos are strange, and we can't stop watching.
We first discovered this phenomenon with this video , and from there, we went far down the Lego-engine-exploding rabbit hole. The creator of the above video, YouTuber sayaman, made another video with an engine using grapeseed oil as a lubricant. The pistons gave out.
Another YouTuber, , builds various Lego motors with the goal of making realistic engine sounds, again often destroying his work in the process. One video shows a Lego V6 spinning up to a claimed 12,000 RPM, exploding at the end.
YouTuber nugru didn't have a full-on explosion with this V6, but when spinning it up to 14,000 rpm, the flywheel launched clean off and the engine started smoking.
Click through the related links on these videos and you'll find plenty more clips of crazy Lego engines being put through their paces. It's a weird trend for sure, but we applaud the creativity and are totally mesmerized by these tiny motors being run to their absolute limits.
