Tape Measure Launchpad

I hopped down from the coffee table, ready for a brand new challenge! Right by the baseboard, someone had left a heavy yellow tape measure lying flat. A shiny metal tab poked out from the slot, looking totally locked in place. I dropped into a firm crouch, hooked both hands around the metal lip, and gave a ferocious backward heave! With a sharp zzzip, the thin yellow steel strip slid out, bending into an arch high over my head. My boots skidded on the floorboards as I held the tension, grinning at this awesome springy springboard!
