Here is a concise summary of the tunnel project video:
**Project Overview:**
Creator Colin Furze is building a secret tunnel from his shed to his house and eventually to a bunker in his backyard.
**Video Summary (Part 6):**
* Furze continues digging the tunnel, focusing on the section leading to the house.
* He creates a system to determine the tunnel's exact location relative to the house's floor plan.
* A second ventilation hole is drilled to ensure proper alignment.
* Steel support beams are installed, and a corner section of the tunnel is successfully built.
* A "utility tunnel" feature is added, including a recessed window and a "Plinko"-style game.
* Concrete is poured to secure the structure.
* To alleviate logistical challenges, Furze invents a "Minecart" system to transport debris along the tunnel.
* The video concludes with the minecart's successful testing and hints at upcoming connections to the house, bunker, and possibly the front of the property.
Here are the extracted key facts, each with a number and in short sentences, excluding opinions:
**Tunnel Project Facts**
1. The tunnel is being dug from the shed to the house and eventually to a bunker at the bottom of the garden.
2. The tunnel's destination under the house is the pantry.
3. A ventilation system is being implemented, including holes to the surface for air and concrete pouring.
4. A mapping system is used to coordinate the tunnel's direction and location in the yard.
5. The tunnel's ceiling is supported to ensure safety.
**Progress and Measurements**
6. The tunnel's progress is marked, with a reference point at the edge of the floorboards downstairs.
7. A single bucket of rubble weighs approximately 48 kilos.
8. The daily rubble removal averages between 3 to 3.5 tons.
9. Multiple holes are drilled to the surface for ventilation and concrete pouring (at least two mentioned).
**Infrastructure and Obstacles**
10. There is a sewer pipe and mains water pipe running under the back of the garage, which must be avoided.
11. A gas main is also a concern, located on the other side of the tunnel's path.
**Tunnel Construction and Features**
12. Steel reinforcements are being installed for the tunnel's structure.
13. A utility tunnel concept is being implemented, including features like a recess window.
14. A "Plinky Plonk" game is integrated into one of the tunnel's walls.
15. A minecart system is designed to facilitate the transportation of rubble and materials.
**Minecart System**
16. The minecart system uses rails made from 20mm box section with flat holds.
17. The system is designed to reduce manual labor in transporting materials.
**Upcoming Plans**
18. The next phase involves connecting the tunnel to the house, potentially revealing the house foundations.
19. Future plans include connecting the tunnel to the bunker in the back garden and possibly extending towards the front of the house.
