Amid the hot weather, a high school student created a 'mobile electric fan' by adding a skateboard to the bottom of a classroom fan, allowing it to move from side to side with the wind's push, earning praises from many netizens as the 'King of Life Hacks'. Another cooling hack involved sticking green oil essence-soaked adhesive tape to the fan to lower the temperature, with a measured 2-degree decrease in just 2 minutes. However, a physics teacher cautioned that the green oil essence evaporates over time, limiting its long-term cooling effects.
