World’s Smallest Hydraulic Jack

We can’t think of any practical reason you’d need a car jack that fits in the palm of your hand. But where there’s a will, there’s a way. Maker B took the time to craft a 1/5th-scale hydraulic jack from steel, brass, and copper. It not only looks amazing, but the tiny jack is fully functional. Maybe he can use it to change tires on an R/C car.
