Penny Floor - don't know if I would have the patience for a whole floor. but a coffee or patio table would be nice! Also an easier way to do it is to put out the pennies then flatten then by, I don't know, maybe a broom or some thing.
I had to find this as I had remembered seeing it before. The Nat Geo channel decided to dress up Buses as Great white sharks and used the doors opening and closing to show the passengers being "eaten" by the shark.
