Inspired by the "Dubai Brothers", the host (Stephen) and his companion (Grace) attempt to live **underwater for 24 hours** in a heated pool (98°F).
**Setup:**
* Create an underwater kitchen table with chairs
* Set up a bed with mattress and weights to keep it submerged
* Add decorations (e.g., a plant, later weighted to sink)
* Gather food, snacks, and utensils (ensuring pool safety, e.g., no glass)
**Activities:**
* Testing various items to see if they float or sink (e.g., pillow, lamp, plant, cans, forks, plates)
