Acoustic Tuning

Carrying my curved zip tie loop out through the patio door, I made straight for the shaded zone under the wooden bench! Right beside a fallen oak leaf, I spotted an empty fluted bottle cap resting face up on the soil like a parabolic receiver dish! I wedged the rigid white strap across the crimped metal teeth. Snap! It slotted into the flutes, standing straight up like an open radar dish. With my brown rod gripped tight, I gave the tin rim a sharp tap—ting! A clear ring hummed right through the yard! Satellite dish ready!
