You already saw the most kiwis sliced on one minute with a samurai sword while standing on a swiss ball. Now it’s time for most grapes sliced in one minute while standing on a balance board. It’s both easier and harder than the kiwis.
The roller board is much easier to stand on than a swiss ball. This helps dramatically. I did have one of the grape pieces roll under the balance board which made it harder to roll until I squished the grape. At first, I didn’t realize what was happening and worried I might fall off.
The grapes are harder to slice for 2 reasons. The first is obvious: they’re much smaller so I have to be more precise. The second is that the sword doesn’t slice through them as easily. I think it might be for a couple of reasons. The skins are a little bit tougher than kiwis and have a little more give so it takes more force to break the skin instead of just bouncing off of them. The other is that the grapes have less mass and momentum than kiwis so it’s not hard for them to just bounce away vs the kiwi is going to keep on coming even when it gets hit.
Jonathan got about 70 grapes thrown in the minute and we found 114 grape pieces on the floor when it was all over.
