Steve, Yes, the version in the video is getting warmer...but not close enough to call it a win. The one in the video is maybe 5' tall. By the looks of it, they used 1" instead of 1 1/2" PVC. If i get a chance, I will take pictures/video of our version and post to youtube, then link from this site. Hopefully you and the entire Ladderball club will be impressed! I think you will be.
I scanned through this website a little bit, but did not find a version of ladder ball that my friends and I created last summer. The idea spawned from playing the normal 3' 6" ladderball at a campsite. We are all avid thinkers, tinkerers, and builders. So it began: 7' tall ladderball. We measured all the dimensions of the regular version, and basically doubled everything. Using 1.5" PVC instead of 3/4", we built it all from scratch. The design is simple to understand, and anybody with a basic handsaw and tapemeasure (and a basic understanding of measurements) can create this monstrosity. You will need some 1.5" t-joints, 45 degree elbows, and plenty of straight pipe. For the "bolos", we used tennis balls. To connect them, an "eye" bolt was poked into the ball, and washers and nuts secured it on the inside and outside. Of course, you will have to make an incision on the opposite side of the ball from the bolt hole, but it has little effect on the gameplay. The cord between the tennis balls was also doubled. I know that it sounds like it wouldn't play worth a crap...because we never thought it would work either. But when all was assembled, we placed the "ladders" 40' apart, and the tennis ball bolos played just like they should. All the physics are very similar, and it is twice the fun of the small version. Granted, small childern (usually under 12) find it very hard to throw the bolos that far. But for grown-ups, it's perfect. I would encourage all who read to give this a try, it's a summer's worth of fun!
