I spent another hour this morning shifting liquefaction from the back lawn of a neighbour’s place. The video above (thanks SciBlogs for the link) provides a stunningly good illustration of just how the sand/silt liquefies when shaken.
Wow, isn’t this a great video to show liquefaction. Thanks for sharing it.
Many thanks for this awesome visual Derek. Can I put it up on our class blog? What a great video! All credit to you of course! Hope the roses survived!
It’s a great video eh, Carol – but I can’t claim it as my own – it’s freely available on YouTube (referenced on my site).
