The creator of the video built a miniature scuba tank inspired by James Bond and Star Wars. He improved upon his previous design by adding two more CO2 cartridges, increasing the air volume to 120 cubic centimeters, and adding features like a mouthpiece, underwater lights, and a laser watch. The device allows the user to breathe underwater for around 5-6 minutes, but the creator emphasizes that it's not safe for others to try and that scuba diving should only be done with proper training and equipment. The video showcases the device's capabilities and features a thrilling chase scene with jet skis and a drone.
