Spinning drum

Spinning drums are gimmicks that appear in Sonic Adventure 2 and Sonic Adventure 2: Battle.

Physical appearance
Spinning drums are cylinder-shaped spinning devices that appear to be made of glass and steel. It has green arrows running across it in the direction that Shadow is supposed to go. On the two ends of spinning drums, there are metal plates with the Project Shadow emblem on it, which may hint that they were created by Gerald.

Overview
Spinning drums are capable of altering the direction of one’s gravity, pulling nearby people towards them and making it so that the user will end up standing on the surface of the drum as though it was a normal surface. The user then can walk up and down on the cylinder until they reach the top or bottom. When standing on the surface, the player will constantly spin around the spinning drum even when standing still. Spinning drums can be laid out either vertically or horizontally.
