  • what is the instrument being played at 1:38?

  • I wonder how one of these would handle an earthquake.

  • Extremely well! This construction method has been rigorously tested and passed by California State Building Control and has comfortably withstood simulated seismic activity up to the maximum capability of the test rig (5.7 Richter Scale). The structure, which has minimum or no foundations, is based on a rotated parabolic arch with a tensioned ring beam between each layer and integral buttressing enabling it to withstand vertical and lateral movement.

  • @earthboar There was barbed wire on the bags. What it's for? Is it necessary?
