Sonic Alarm

Do you find it hard to get your partner or the kids up in the morning? Well the Sonic Alarm is the perfect solution to your problem.

Simply pull the pin, yell an emphatic “fire in the hole” and lob the grenade into the sleeper’s room. After twenty seconds a very annoying noise (there are three volume settings) will blast out from the alarm.

That’s not all however, what makes this especially great is that to stop the alarm the sleeper has to find you so you can put the pin back in. It’s stupid, and brilliant, and 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.
