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!!

With just six days remaining, I'm diligently continuing my preparations for the upcoming voyage across the Pacific from Hawaii to Japan. Today's task is to remove Starlink, as I'm eager to take it on the journey. Unfortunately, this process has been delayed by a day due to yesterday's evacuation of the coastline here in Okinawa, prompted by a Tsunami alert following the deadly earthquake in Taiwan. A 3-meter wave was predicted, but thankfully, it never materialized. Stay tuned for further updates as I progress. Keep following along! It`s Never Too Late https://www.nevertoolateacademy.com/
