On May 2, in Zhejiang Province, China, a woman hiking in the mountains came across a stone with a groove exactly the size of a mobile phone. When she placed her phone on it, the screen surprisingly showed that it was charging.

The woman shared the scene online, and it instantly sparked widespread discussion. Some joked that the mountain was so high-tech it now had wireless charging. Others humorously speculated that it was an ancient charging station, while a few claimed the stone might contain special materials capable of converting solar or thermal energy into electricity.

As the debate grew, the woman revealed the truth: it was all a prank. She explained that it wasn’t wireless charging at all — she simply noticed the groove matched her phone and decided on the spot to play a pre-recorded charging animation on her screen.
