Optical illusions are great, but this looks so convincing!
I'm glad you guys like the "hover Effect". It is easy to do too, but it can be done only with transparent glasses and liquids.
If you observe in the wall behind there are 2 spotlights facing down to the ground. The glass was placed also under one of these spotlights too.
The transparent glass and liquid (beer) let the light go through, alter slightly its color and also reflect the light on top of the wooden bar. What makes the glass look like it is hovering in the air is the light from the bottom part of the glass to the wooden part of the bar (that yellow intense lighting that looks like a sword).
Also observe that inside the glass and above the beer level there is also a yellowish ring around that comes also from the spotlight from the ceiling and of the mirroring of light through the transparent liguid.
