How did I forget to put this into my blog?
Once again this Summer some friends and I got together to fire our air cannon. You can see a short video I assembled of last year's mayhem here. This year, one of our number included a videographer and editor who shot footage and put together the following video.
Our plans for next Summer are to rebuild the cannon with a faster valve to make it more efficient and to set up some high angle shots to simulate meteorite impacts. There has also been some talk of making sabot encased, fin stabilized, steel rods to... well... shoot at stuff.
