    another fun fact, the normal hole of the needle could not be used in its normal fashion to administer the tranquilizer due to the pressure difference between mode of travel and the injection site. once the dart is released from the blow gun, the liquid would begin to expel out the tip and losing fluid before making contact with the target. this is because the dart is lightly pressurized to eject the fluid without having someone press the syringe to force it out by hand. the tip is also at risk of being plugged by skin or whatever it may puncture through, like tough scales, or thick hide, that suddenly the only hole of escape for the liquid is plugged and the tranquilizer will not inject the liquid even though proper contact was made. so the tip is plugged intentionally, and used as a spear point to penetrate a hole for the whole needle to pass and then the side hole is rigged to release the cover once its at a deep enough level into the target that the liquid can release. the only downside to this design is you have to rely on over shooting with force than undershooting because if the puncture only barely passes the tip, it may not trigger the slide off cover for the side hole and the tranquilizer will most likely just fall off it its dangling from the somewhere. i must admit that all of this is entirely my own conclusions based on observations from the slow mo videos shown here. so i am pretty sure i have no idea what i am talking about :D

    So at 8:54, when they analyze the motion of the rubber slider, I counted 12 frames from the tip hitting the target until the whole syringe comes to a full stop. So that's 4ms if I'm not mistaken, as they've been filming at 3000 frames per second. To put it in perspective: The sine wave of the electricity grid has a period of 20ms in Europe (50Hz) or 16.6ms in the US (60Hz).

    Being born in and never leaving America, I started watching dark British movies when I was in my formative years.. films from people like Guy Richie and Matthew Vaughn and Danny Boyle. As such I quickly latched on to a whole bunch of the vernacular, and ended up using a lot of them in my day to day operations, including the more expletive ones.. but having found the Slo Mo guys here a couple months ago and plowing through most of their catalog relatively quickly, I am somewhat perplexed to report that I have noticed that I started saying 'flipping heck' quite a lot lately. And I'm not exactly sure how I feel about it. I have always been a big proponent of cursing. When used right it can be descriptive, funny, even poetic sometimes. I picked up subbing Flub and Flip from the Flight of the Conchords, but have always been rather resistant to tone down the words I chose to use to communicate with the world around me.. but I guess Dan has rubbed off on me a bit 🤨😳😉😏 cause I'm saying flipping heck all the time now.. so thanks for that guys.. I think.. 🧔🏻
