When I returned with the van to the restaurant where the World was tied in front of the large windows the ball seemed a little flatter than the cool evening air should have made it. I rolled it over to the van and put some air in it. I noticed a few minutes later it was getting soft. I put more air into it till it was hard and then I heard air leaking. I found a hole, a knife hole. Rather than letting all the air out and pull the bladder out I opened the fabric with my shears and got out the waterbed repair kit and applied glue to the hole and a rectangle of patch. I will have to wait and see if it holds. It could have been worse.
Sleep well you mischievous "ne'er do well". Goodnight Saint Paul.
