HOLDING AN EXPLOSION (at 20,000 fps)
Added 2016-06-22 14:29:27 +0000 UTCI always thought firing from the center was the best way to do it. Turns out I'm probably wrong.

Destin. I'm a retired engineer teaching physics and chemistry at a HS in Kentucky. I've been using tater cannons to teach projectile motion for two years now. I've also had a student design team work on cannon design and they have found something that reminded me of SED #156. We've found that a vertically oriented combustion chamber may result in greater impulse at a given barrel length. I'd love to have your thoughts if your interested. Data is preliminary but promising.

2017-10-02 18:34:59 +0000 UTCThis reminds me of a video I saw earlier in the year where they showed how the new Formula 1 engines have reinvented fuel efficiency using Turbulent Jet Ignition: <a href="https://vimeo.com/166635777" rel="nofollow noopener" target="_blank">https://vimeo.com/166635777</a> They solved a lot of the unburnt fuel problems you describe by sparking a mini-chamber which effectively injects flame into the main chamber for a smoother and more powerful burn.

2016-06-26 15:18:01 +0000 UTCSehr geehrter Destin, you are awesome! The artistic quality of these pix is amazing. One of your best. Additionally: yeah. stick a glo in the dark stick into the potato the next time, or dip it in something flourescent and UVlight the heck out of the thing. Add long exposure to see the flightpath of the projectato.

2016-06-24 01:16:28 +0000 UTCPlease tell your friends at Audible that I recommend them all the time because of you. I'll continue to tell my friends that your videos are not only worth watching, they're worth supporting. (It really was pretty, wasn't it?)
2016-06-24 00:54:32 +0000 UTCNice work!
2016-06-23 01:33:59 +0000 UTCYea! Great video. How about turning that gun into a turbo prop or something else with a spinning turbine in the middleπ
2016-06-22 23:54:13 +0000 UTCNoice! Great vid Destin, keep em' coming!!!!!
2016-06-22 20:51:24 +0000 UTCThis is definitely my new favorite SED video.
2016-06-22 19:46:19 +0000 UTCAwesome. I love how giddy you get after every shot. The slow motion video is incredible. Thanks for sharing.
2016-06-22 16:59:33 +0000 UTCLove that guy at the end!

2016-06-22 15:44:44 +0000 UTCMan thats cool. What pipe did you use for the chamber? I'm always afraid of mine blowing up. I use Black ABS pipe.

2016-06-22 15:21:38 +0000 UTCAmazing video Destin! I loved the slow motion shots of the flame and how you explained why the air was flowing like it is. Great job, thanks!
