Sonic Grenade

Office warfare has just got irritating! The Sonic Grenade has to be the most mind shatteringly annoying thing in the world, and we can't get enough of it! With three pitches of skull shattering sonic terror, you're sure to crush your enemies into submission.

The best thing about these beauties is how easy they are to use. Just pull the pin and lob (ala Arnie, Sly or whatever action hero you want to imitate) at whoever you want to annoy, twenty seconds later the grenade goes off. Simple. And the only way to stop the sonic shrieking is to replace the pin, so if you want to be kind you can chuck it in with the grenade. But we all think the best thing to do is keep the pin in your pocket and run for cover!! The Sonic Grenade isn't just for office fun though, it's perfect for annoying your mates with hangovers, waking up the kids or just getting attention. All that's left for you to do is shout 'FIRE IN THE HOLE!!'

• Requires 3xAAA batteries (Not included)
• 3 screeching sonic pitches
• 20 second delay before going off
• Pretty damn annoying!
