A week ago Disney showed us what some of the interactive elements would look like. Now we have a video of what the "gem washing" and other elements look like.
The touch screen game does look pretty fun and there are some other games as well. Spinning barrels of diamonds create projections on the celling of characters from Snow White. There is a water element where falling columns of water are seemed to be tied to musical notes.
Only downside of these interactive elements is having to keep moving forward on the line. What do you think of what the Mine Train has in store?
