You've heard me talk about ballistae before and other much larger siege engines. Ones that you'd want to launch pianos, dead farm animals, and large chunks of masonry from. Despite Mr. Spanky's penchant for the large and destructive today he focuses on the small cool and annoying. But still it's all about siege engines and specifically the catapult.
I really like the Instructables web site: people post things that they actually make with their own two hands, which is an art lost here in our shrink-wrapped bargain store consumer oriented society. This instructable is the step-by-step guide to creating your own mint-launching catapult. The materials are simple: Altoids tin, coat hanger, rubber bands, electrical tape, small piece of cardboard, measuring or other plastic spoon, paint, wire cutters, hot glue, scissors, and pliers. You can find them around the house. The tools you can find in Dad's toolbox and he won't mind if you use them AS LONG AS YOU PUT THEM BACK AFTERWARDS YOU LITTLE TROLL!
Sorry. It's a touchy point. Mr. Spanky's son has been known to leave a trail of discarded valuable tools all over the place like crumbs in a Hansel and Gretel story when he works on his projects. IT'S NOT TOO MUCH TO ASK THAT HE CLEANS IT UP, RIGHT? RIGHT?!!!
