In the sand box

Speaking of sand boxes and vibrations:

Have ya’ll heard the story about Brian Wilson and his sandbox? Sometime in 1966 Brian had the idea of having the grand piano in the living room of his Bel Air mansion installed within a sandbox, so that he could feel his feet in the enclosed sand as he composed songs. Whatta nut. I don’t know if he had that done before or after writing "Good Vibrations". I also don’t how long it was before it became apparent that the Wilson family cat(s?) viewed the sandbox as a litter box, and it was therefore removed.

And then there was the time of while shopping in the Tower Records on Sunset Blvd. that Brian suddenly felt nature calling. He asked a Tower employee if he could use the restroom, and was told the restroom was for employees only. Brian walked over to an end cap, whipped it out, and sprayed away. Like I said, whatta nut.

There is a thread started on 3-27-2020 by @soma70 entitled "Sandbox Design Advice". In it I recommended silica sand, a non-organic, man-made material used in sandblasting. Silica sand is superior to play sand for this application in that it doesn’t absorb moisture, and is therefore incapable of supporting the growth of bacteria.

Silica comes in different "grades", just like lead shot. When I was using the Bright Star Big Rock isolation boxes, I settled on No. 60 grade sand. It is the optimum size, anything smaller (the particle size, a larger number connoting a smaller size grain) being too powdery.

I found Silica at a construction supply yard, but I think even Home Depot sells it. It’s cheap, like under ten bucks for a fifty pound bag (this was twenty years ago).
