Bouncing items glitch
From Halopedia, the Halo wiki
Template:Ratings The Juggling Plasma Grenades is a Halo 2 glitch.
How to do it
In Halo 2 go onto the Campaign level The Arbiter on any difficulty. As the elevator goes down toward the room where you battle more Elites and Grunts, throw a plasma grenade upwards. When it hits the floor of the moving elevator it should bounce up and down and not explode (it will explode when the elevator stops). You can do this with as many plasma grenades as you want. This also works with weapons. To do this, dual wield two weapons and drop one above the elevator while it is moving. This is only because the frame rate is reducing as the elevator goes down.
Effect
The plasma grenades should bounce up and down without exploding until the elevator stops moving, when it does the plasma grenades will explode.
