My own invention, thought up, drawn and brought into existence by founder Mike Dabbles.

Dual rotating, heat holding monster. 6x35mm. Solid Core section retains tons of heat. 4 Holes in hollow sections cause pillar to rotate on its vertical axis in addition to sweeping the walls of the banger. 

We punched a 4 holes through either side to improve drainage for those of you who like to load your pillars. 

This also more effectively transfers heat to the solid core, leading to better heat retention, and more glob destruction.
