Will Our Hand-Dug Sandstone Tunnels Collapse?

When I show videos of our DIY tunnels at Sandland, a common question is "will they collapse?" In this video I attempt to explain why Sandstone is stable and relatively safe with a few simple precautions.

Another frequent question involves the difference between sandstone and limestone. I also address this briefly. However, I'm not a geologist, so my explanations are not at all scientific!

Please note that this is for educational / informational purposes only and I recommend consulting a real geologist if you want to try this at home! You should NEVER dig a tunnel in dirt, loose sand, sand dunes, etc, as those are completely different! If you *do* plan on digging a tunnel or cave of your own, talk to some experts first and do some research into other tunnels in your area to see how they were made!
