Nash in action (above) and after (below).
Grant was able to get some pretty good float time.
This is Grant and Luke (you'll have to trust me) rolling down the hill in the Zorb. We got in our swimming suits and they put some water inside the ball so we sloshed around in it.
Nash and I went together after Grant and Luke. We tried to stay upright in the ball for as long as possible - but that lasted only about 3 seconds. Here's Nash exiting the Zorb at the end of our run.
