Thanks to two local artists we spent the morning watching ducks drift down stream in Krutch Park with many other Market goers. The three yellow rubber ducks were fished-out with sticks and carried back to the head of the man-made stream several times. We got a demonstration of the complexities of hydrodynamics when the ducks got stuck in eddy pools that sent them up stream against the general flow of the water. Some experienced kayakers had the best predictions for how the ducks would move as they floated over the little waterfalls in the stream. Sticks were eagerly deployed by the children to get the ducks out of the undercurrent rolls.
We love this simple high-joy interactive art project and hope that the city will let the duck stay in the stream!
