#c_lang#drone#esp32#quadcopter ESP-Drone is an open-source project using ESP32 chips to build a simple Wi-Fi drone you control with a phone app or gamepad. It offers stabilize, height-hold, and position-hold modes (with extensions), plus clear code for STEAM education, based on Crazyflie firmware. You benefit by easily making a cheap ($30-50), lightweight drone in 6-8 hours for fun indoor flights, learning electronics like sensors and motors, and customizing with open code—no extra radio needed. https://github.com/espressif/esp-drone

We asked: Is water wet? Water isn’t wet by itself; wetness describes a liquid’s ability to adhere to other surfaces. Water’s strong cohesion and surface tension make it resist spreading on itself but allow it to wet other materials. Adding surfactants lowers surface tension, helping water spread more easily. 💧🔬 [Source] @googlefactss #WaterScience#SurfaceTension#Cohesion#Adhesion#ScienceFacts
