A can mixing device is disclosed. The device may include a base plate having a base plate proximal surface and a base plate distal surface. The device may further include a first rod having a first rod proximal end and a first rod distal end. The first rod distal end may be attached to a center portion of the base plate proximal surface. The device may further include a top plate having a first hole in a top plate center portion. The top plate may be configured to slide along a first rod length through the first hole. Further, the top plate may be attached to the first rod proximal end via a fastening member. Furthermore, the device may include a connection member attached to the base plate distal surface. The connection member may be configured to removably couple with a power tool configured to generate a device reciprocating movement.
