Clear Tube Speedway

I ducked into the open doorway of a neighborhood hardware shop to check out the rows of shelves! In the plumbing aisle, a huge roll of clear, flexible vinyl tubing was resting on a lower shelf, with its open curved end spilling right onto the polished concrete. Right near my shoes lay a shiny steel ball bearing. Without thinking twice, I picked up that heavy little sphere, scrambled onto an upturned plastic bucket, and dropped it straight into the tubing mouth! It made a rhythmic whirring clatter as it zipped through the curling transparent spiral, banking the bends like a roller coaster before shooting out onto the floor. Best transparent tunnel run ever!
