Just watched something on the taofledermous channel where they were talking about blunt body concept that NASA was researching. Would be really interesting to see some schelrin photos of the stacked objects they made for the shotgun. <a href="https://youtu.be/n_UQVvZtBOs" rel="nofollow noopener" target="_blank">https://youtu.be/n_UQVvZtBOs</a>

2018-12-13 23:01:06 +0000 UTCThe bullet has a tailwind from the muzzle blast; as that dies down and the bullet gets out into essentially still air its airspeed (which is measured relative to the surrounding air) suddenly increases to its speed over ground (give or take wind).
2018-12-07 19:30:14 +0000 UTCI love the firearm related stuff. Keep it coming

2018-12-06 15:24:35 +0000 UTCSo I assume that the shockwave on the bullet doesn’t happen until a few inches away from the muzzle because the surrounding gases are also traveling at high speeds? Is going supersonic a relative thing?

2018-12-05 01:09:01 +0000 UTCExcellent stuff, as usual. Don't worry about apologizing for your use of firearms in your videos. We're patrons because we love what you do. Just keep doing what you do. #rockon

2018-12-04 04:35:49 +0000 UTCI'm all ears, how do I avoid this? Does it put the video description in the email?

2018-12-04 03:56:57 +0000 UTCAfter he met the astronaut he asked if he could just ride his normal bike. Of course you can't say no to that so i'm pretty sure he cannot ride the backwards bike anymore.

2018-12-02 04:12:39 +0000 UTCYou shouldn't have to apologize for appreciating firearms, they aren't inherently evil.
2018-12-01 18:27:22 +0000 UTCVery interesting! But my favorite part might have been seeing your son helping make dinner -- they grow up so fast! Does he still know how to ride the backwards bicycle? Was he able to retain the ability to ride both (unlike you) at the same time?

2018-12-01 13:05:29 +0000 UTCWhile I get the fascination with firearms, I liked your cat and insect videos better: Please more of those!

2018-12-01 09:54:09 +0000 UTCWhilst I have personally never felt your videos involving firearms have glorified them, I do appreciate the caveat you have included at the start of this video to clarify why you find studying projectiles so interesting. There's certainly no suppressing your enthusiasm for getting smarter every day!
Daniel Turner
2018-12-01 08:04:29 +0000 UTCThis was so extremely cool and really insightful. Never really thought about how a suppressor would work but what you showed makes sense. The grains of propellent in front of the bullet is an interesting side effect I wouldn't have expected either. Thanks for the hard work!
