Sam Berland created a wonderful shot glass gimmickwith his thimble act many years ago. Denny Haneyimproved the gimmick, and I took the concept evenfurther to produce a new safe, reliable and foolproofcover, which is what you have right now. I also made itlarger so it can be used to produce a tall and high profileZombie style glass with the same reliable cover as mySure Shot, Wine Shot and Big Shot. This glass is a utilityitem that can be produced in many ways such as theclassic waistband load ala Bob Read's BottleProduction, or keep it in your back pocket and ring it inwhen necessary as a kicker, like in my Matches Meltroutine from my Standing Up on Stage Series Vol. 4 Skilland Danger.
