Varnish makes me think of boats. Wooden boats. We have one group that does not use much varnish: our Kinetic Sculpture racers. Human powered, on land, on sea and through the mud bog. All sizes and shapes and themes. Wonderful!
We have helpers for the teams in the water, and here two kinetic sculptures are making their way to land. The water is a few degrees above 50 and they have to take turns exiting on the ramp. We have Kinetic Kops to protect the public and the racers.
For the Daily Prompt: varnish.
