"On Water and Ice" can the spectators eat the SNOW at the end?
In the video, we see the spectators freely eating the ice before the water is poured in. By the same token can the spectators eat the SNOW at the end of the effect, or has the snow been chemically treated to become "snow"?
Also, do you start and end clean? Can the cup (from which the ice was put in and from which the snow was poured out) be examined both at the start of the effect and at the end of the effect?
