An 18-wheeler pulled up right next to us on the corner. We stared in awe as a huge mechanical arm hovered over a trash can, just hesitating, and then
launched toward the iron handle on the top of it.
As the trash can was picked up it made me realize that the trash can was five times larger then it's normal appearence (see photos of huge container beneath the surface). The big metal crate's contents was dumped into the truck, and the crate returned to it's normal position.
