This is the most fun you can have with a bag of spuds, a can of hair spray and a couple of pieces of PVC. We’ve looked long and hard for a set of plans that lived up to our standards and now we’ve found them. This book includes plans for The Econo-Blaster ( a Vegi-Cannon that will launch a potato over 200 yards and cost $20.00 or less to build), The Master-Blaster , The Magnum-Blaster and last but not least The Spud Pistol. 37 pages, 51/2 x81/2 , illus., photos.
