India, Aug. 26 -- When two children, aged 7 and 11, went missing from Meerut's Hastinapur on Sunday afternoon, their families panicked and filed a police complaint. They were later found to have disappeared to recreate the 'Secret House 24-Hour Challenge' that has taken over YouTube! During questioning, the children told police that they had watched the gaming videos and decided to try it themselves. The Secret House 24-Hour Challenge is a popular online trend where creators build hidden rooms or secret bases and try to stay concealed inside them for 24 hours. A viral example is the video by the YouTube channel Mr. Indian Hacker that has surpassed 10 million views! Here's how the game works: The concept: The team constructs a fully functional underground bunker or house hidden deep beneath the ground. It is equipped with facilities like a secret entry, a gaming setup, a kitchen to cook food, and electricity. It is engineered to remain completely hidden or disguised from the outside world. The goal: Creators lock themselves inside the hidden underground space for 24 hours, testing whether they can survive without being discovered or leaving. The participants must also follow strict self-imposed rules or complete mini-tasks while staying hidden in their custom-built secret space. The appeal: The viral video includes a standard safety disclaimer: "This video is made only for entertainment purposes. All scenes are performed in a safe and controlled environment... Please do not try to copy or recreate anything shown in this video." However, the challenge is drawing young, impressionable viewers in, as it seems like an adventurous, high-stakes version of hide-and-seek....
