Tension Test

Found a heavy rubber band looped around a metal tape dispenser. Prime slingshot material. Wedged myself into the elastic loop, dug into the cork mat, and backed up with everything I had. One inch. Two inches. Trajectory locked onto the open bedroom door. Then the dispenser gave out. Screeched three inches forward across the mat, dumped a roll of clear tape against my back, and snapped the band straight into my belly. Sloppy ballast. Next test needs an anchor that actually holds.
