Grenade Bouquet (Fallout: New Vegas)

The Grenade Bouquet is a weapon

Gameplay
The grenade bouquet is a cluster of three frag grenades hung from the ceiling. When triggered, either by simply walking into it, shooting it, or hitting the nearby tripwire/pressure plate, the pins are pulled and the three grenades fall to the ground, exploding after a few seconds. Both the tripwire and the grenades themselves can be disarmed, the latter of which requires an Explosives skill of 30.

Doing the latter adds the three grenades to the player's inventory. If the player lacks the required skill to disarm the trap, they may be able to shoot the rope holding up the grenades to make them fall and detonate away from the player.
