    • Very clever to be sure! It sort of reminds me of playing in grain stored in grain elevators. One doesn’t do it because there is a ‘no return’ if you unfortunately get sucked down into one….but the feeling of the gravity pull is very alluring. Now, I don’t think this device will be under next years’ Xmas tree; the concept is terrific. It would have a lot of therapeutic features for many medical treatments….add a little heat and go for a soothing sit in the ‘sand-tub’. The tub would be for kids older than 17 and adults who want to get a relaxing massage with warm soft sand. It’s got a lot of great uses…..and it has its’ drawbacks as well but doesn’t everything. I for one wouldn’t go water-skiing or use a skate board but I think I’d be in for a nice warm & rejuvenating sand soak. It would have to have all the safety features of a regular hot tub…..fenced in…etc. but this invention would go a long way to restoring some much needed downtime.

    • Wow, I totally disagree with using hot sand as a children’s toy. A lungful of that would be deadly.
      Beds of warm encased sand are used to promote healing and comfort in patients with severe bedsores.

    • Sounds like this is what happened in the Jamaican earthquake of 1692, when entire houses disappeared into the sand and bobbed to the surface intact some distance further away.
