I believe that the lake show will be a mix of world of colour and illumiNations as in the concept art there is a small lake near the frozen land possibly storing themed floats and then the lake would have to be deep enough for the floats to go over and the pyrotechnics to rise up! I think Disney will be thinking about using fireworks and fountains to make the show more colourful and it is very likely that there will be projections from the mist! Quick question does any one know anything else about the show and when the show will debut?
