Micro Sonic Grenade
Feel the need to prank someone, or just need to get some payback? Pull the pin on this micro sonic grenade, throw it and wait for payback to ensue! The variable timer can be set for 5, 30 or 60 seconds before the 110-115 decibel siren begins to annihilate your victim. The annoying scream packs a bunch comparable to the loudness of a power saw. Perfect for the quiet workplace!
