Mechanical "chopsticks" grab it by the grid fins with 10 cm precision. Interesting fact: the water system suppresses a shockwave of 10 gigawatts — equivalent to a small nuclear power plant!

Just a water bottle in the roof = 60W bulb brightness! 📌 The science: •Sunlight refracts in water (lens effect) •Bottle filled with water + bleach •Installed in roof hole •Provides 5-8 hours of daily light This idea illuminated millions of homes in poor regions! Simple physics changing lives. Author: unknown If this is your video,please DM For more brilliant inventions — follow! @jem_facts_

Jem_Facts_ on Instagram: "Imagine a mechanism with 585 components that can replicate your signature — without a single chip or line of code! The Jaquet Droz Signing Machine pays homage to 18th-century automata. The device reads the signature profile using a set of custom-machined cams that precisely guide the pen. Each mechanism is hand-assembled and calibrated to the owner's unique signature. A 4-digit code ensures security. One wind allows for two signatures before requiring manual rewinding.
