Jacob got the book Backyard Ballistics for Christmas. The first project he and his Dad made was a potato gun.
With a little spray of hair spray(2sec) and a lantern igniter, you have a potato that ends up in the pasture. Or if you're my husband you spray more like 5-6 sec and the potato ends up in the road...no more of that!!
My neighbors I'm sure are enjoying this lovely show of boyhood, but I can't help wondering if they are thinking "Why are they always pointing that thing at us?" If my dear husband isn't careful the potato might end up in their living room:)
