Challenge Setup

• Host: Vlad A4 with teammates Glent and Kobyakov
• Prize: $1000 for winner
• Location: Pool with glass walls for clear underwater visibility
• Format: Each participant gets 3 attempts, 3 constructions each
• Total: 9 dives to determine best time
• Viewers encouraged to comment predictions and subscribe

Warehouse Material Gathering

• Vlad's selections: Barrel, coating, tape, green tube, pillow, dog food for dachshund
• Glent's selections: Pump, weights, dumbbells, 5-liter bottle, balloon, tube
  • Strategy: Take air from surface using pump system
• Kobyakov's selections: Tubes, 5-liter bottles, gas burner, awl, zip ties, knives, styrofoam, balloons
  • Plans to build scuba gear
  • Mentions new warehouse coming (4x bigger than current)

Construction Phase

• Vlad's Designs:
  • Design 1: Tube connected to balloon for surface air access
  • Design 2: Transparent plastic container with dumbbells as weights (physics-based air pocket)
  • Design 3: 5-liter bottle as float with breathing hose
• Glent's Designs:
  • Design 1: Pump system with tube for continuous air supply
  • Design 2: Container with weights (similar to previous "24 hours underwater" video)
  • Design 3: Bottle float system with long hose
• Kobyakov's Designs:
  • Design 1: Scuba gear using bottles and balloons as air tanks
  • Design 2: Balloon system with tube connection
  • Design 3: Large dome construction with air pocket

Pool Testing Results

• Glent's Performance:
  • Attempt 1: 1:40 minutes (pump system failed due to physics/air pressure)
  • Attempt 2: 4:00 minutes (container with weights, needed assistant for pressure)
  • Attempt 3: 10:30 minutes (bottle float system, accidentally released hose while celebrating)
• Vlad's Performance:
  • Attempt 1: 3:54 minutes (balloon system worked well until air depleted)
  • Attempt 2: 23 seconds (scuba gear failure, air didn't flow properly)
  • Attempt 3: 5:23 minutes (bottle float system, water leak caused early exit)
• Kobyakov's Performance:
  • Attempt 1: ~1:00 minute (balloon system leaked water, sealing failed)
  • Attempt 2: 30 seconds (barrel system complete failure)
  • Attempt 3: 15:00 minutes (sealed air pocket construction - WINNER)

Final Results

• 1st Place: Kobyakov - 15:00 minutes (sealed air pocket method)
• 2nd Place: Glent - 10:30 minutes (bottle float system)
• 3rd Place: Vlad - 5:23 minutes (bottle float system)

Technical Notes

• All activities performed by professionals under supervision
• Reference to KREOSAN channel as inspiration for scuba gear
• Physics challenges noted (air pressure, container submersion requiring ~200kg force)
