Our Grenade Alarm makes the whole 'getting them out of bed' exercise a very simple and indeed, amusing operation. Looking like an old-fashioned comedy hand grenade, this alarm will wake up pretty much anything. Simply pull the pin, yell an emphatic "fire in the hole", then lob the grenade into the sleeper’s room. After about twenty seconds, a very annoying and piercingly loud noise will blast out. The best part, however, is that to stop the alarm the sleeper has to find you, so you can put the pin back in. It's both stupid and brilliant, but will be the bane of every over-sleeper on the planet. Parents are going to love this, though the soon to be rudely awoken might not. Product Specification:The Grenade Alarm has three volume settings, is about 13 x 8 x 6 cm in size and requires 3 x AAA batteries (not included).China supplier:Email : fangzhengcn@hotmail.com Skype ID : chanceller819
