Speaking of light bulbs, most people now have smart bulbs in their homes, and the brightness of the light can be adjusted. Although we have seen a lot of wonderful bulbs, you must not have heard of the lamps introduced today, because you can light up the bulbs just by knotting the rope. After hearing this, netizens are calling out directly too amazing!
According to Hahao.com, this is a conductive knot lamp designed by celia torvisco. The rope at both ends is made of conductive wire. Tying the two ends of the conductive wire together will form a complete circuit. The light is turned on; and when both ends of the rope are untied, the circuit can be disconnected and the light can be turned off.
