Launch this ear-piercing grenade into a friend’s bedroom and watch them leap out of bed! The only way to stop the screeching noise is to replace the pin which you can hide wherever you like! A great way to shake up tedious meetings or to annoy siblings and parents! The speed of sound: 770mph. The speed of someone fleeing the sonic horror of the brainiac sonic grenade? Immeasurable! Requires 3 x AAA batteries (not included) | |
