Magic Tricks

I really like it as it combines a way to produce a glass of liquid and a way to ditch the device so it is readily available when needed, by combining two known devices as described in the marketing info. It is designed for a particular glass that comes with the effect (you get one gimmick and two glasses). You should be able to find a variety of other glasses to use with the gimmick, for example a narrow mouthed wine glass (which would be more of my preference). The downside is I think it would have been better to buy instructions on how to make such device so it could be used with a glass of your choosing or to make multiple gimmicks to be used with multiple glasses. Having purchased it, I now have the know-how to make a couple clever devices so I can produce two glasses of liquid, one for myself, and one for a spectator. In other words, it was somewhat of an expensive lesson.
