This is a video of Youtuber Brick Experiment Channel demonstrating the LEGO motor and gear system he built that's capable of lifting 102.2kg (~225 pounds). For reference,I can lift twice that with one arm. In his own words while I shotgun two of those little Starbucks Doubleshot Espresso cans back-to-back and fight a wall: Lego PF Medium Motor with gears and pulleys lifts a hefty 102.2 kg. Gear ratio 15:1 and tackle velocity ratio 8:1. Only lego parts were used, apart from for the string. relish! :)
I did relish! Did you relish? "I enjoyed." Heck yeah we did. Feels good, or doesn't it? That feeling doesn't reach as often as it used to. I used to relish things. But those were different times. Or perhaps -- perhaps they were only dreams. *blowing dandelion petals* Just what the hell does Starbucks put in those cans anyways? Keep going for the video,which also includes a bunch of fails and pieces breaking in the moment half, so be sure to stick around for that.
