MY EARLIER POST ON THE POTATO GUN produced this email from reader George Putnam:
Minor comment on today’s entry that you want a potato gun for Christmas…What is REALLY fun is a potato cannon. You can find directions to build one here:
I built one a couple of years ago based on this book, and it is a blast! Who knew that hair spray was such an effective propellant?
(I have one of the potato guns, too. They’re OK, but not nearly as much fun as a potato cannon.)
Okay, now I know what I really want for Christmas.
