In addition, this video also contains several clever methods for performing the Kinetic Rings - the effect where you have two brass rings examined, then make them adhere to each other and can spin the bottom ring.
Also included are bonus handlings for the Raven and a special section on puzzle effects with the Bat. Only one video but so much magic.
