I have an idea
Contact a foam shop. A mold could be made, if designed right, a metal post could slide through the middle to support the table top.
You might have to have a minimum amount made. You could sell the extra ones to Pinsiders. Even a single one, in a corner of a game room could look real good.
Maybe you can flip these over and modify them to work: Its going to be tough to find a Rubber Ring to fit!
I know someone that could mold and cast something that big, but it would be $$$$$$ for that kind of build.
The rigid foam idea wins this all day on cost... durability can be an issue but this is a cool idea for a public space.. would not want it in my home but this would be sweet in a bar/restaurant. Great idea.
