By Andrew Liszewski

Most ‘sonic’ devices are designed to be tucked away somewhere unnoticeable so they can subtly annoy friends or co-workers. That’s definitely not the modus operandi for this Micro Sonic Grenade though. As you can see it’s got a tough rubber outer coating making it safe for tossing, throwing or whatever means you need to deliver it from afar since once the timer runs out (it can be set to 5, 30 or 60 seconds) this thing will ‘detonate’ with an ear-piercing 110-115 decibel siren. In other words you don’t want to be anywhere near it. And when your victim finally regains their faculties and inevitably destroys the grenade with a hammer and/or heel of their shoe, you won’t feel too heartbroken since it only cost you $9.99 from ThinkGeek.
