Sonic Grenade
Sonic Grenade
Ever had trouble trying to get a lazy family member out of bed in the morning? Fed up with with shouting at them to get up, only to receive a not so polite reply. Well there is a solution and it’s called a Sonic Grenade.
Simply pull the pin on the Sonic Grenade, toss it into the room with the hapless sleeping beauty and evacuate the immediate area. Twenty seconds later an exceedingly annoying, ear piercingly loud noise is produced from within the Sonic Grenade, waking up the sleeper in a hurry.
The ingenious thing about the Sonic Grenade is that the only way to silence it is to replace the pin, which means your unlucky victim has to get up and come and find you in order to retrieve the pin and silence the device.
