Echo Chamber

CLANG! I found a giant metal cavern sitting right on the counter! Naturally, I had to test it. Deep breath... SKREEECH! The bowl threw the noise right back into my face, twice as loud! HAHAHA! The steel hummed like an angry bee against the countertop. I tried a raspy growl, then another sudden, ear-splitting shriek! It rattled a wooden spoon right across the granite. Perfect sound amplifier! The whole room definitely heard that.
