Quick test of a tiny QEV cannon firing air at 12atm, viewed through a Schlieren setup (no razor blade). Edited from to 1/4th normal speed. I didn't quite understood the need for a razor blade but without one I still see the flow of air. For me, the razor blade just makes the dot of light smaller(?) If anyone can clarify me what the razor blade really does and where it should be placed (in the source of light or in the camera) I'd really appreciate. Also important to note that this is AWESOME to look with the naked eye but almost the dimmest light can blind you. I covered a tiny LED torch with aluminum foil and punctured a hole with a sewing needle, on the side! so that the LED doesn't bright directly through the hole. Take care with the eyes!!

The Prusik Hitch, helps me go up the mast safely as it allows me to have a safety line when using my Mastclimber. #solosailor #mastclimber @pacificsolo @nevertoolateacademy

On my third research journey up the length of Japan, I’ve returned to Matsue Castle in Shimane Prefecture — the region that’s ranked number one in Japan for twelve consecutive years for the number of centenarians per 100,000 people. Just 48 hours ago, I left my boat in Amami, flew to Tokyo to surprise my son on his birthday, and then took two long trains to reach Shimane, where I’ll be spending the week writing, soaking up the atmosphere, and conducting more interviews for my upcoming book on longevity and community in Japan. A longer video is coming soon with updates from the past few months — including some sailing adventures — but for now, here’s a glimpse of where the next chapter of this journey unfolds. Remember, it’s never too late to get out and about.
