Have you ever been annoyed by having to wake up at night to go to the bathroom? Everyone has experienced the dilemma of wanting to continue sleeping despite urgently needing to use the restroom. For those too bothered to get up in the middle of the night or worried about their children wetting the bed, this special underwear is recommended. It detects even the smallest amount of urine, absorbs it, and then automatically transfers it into a water balloon, which is levitated into the air until morning. When you wake up, you'll find urine-filled water balloons floating near the ceiling, allowing you to see just how much you've peed during the night.
