Coaster Roller


If you were to ride a Radio Flyer wagon over a road filled with acorns, you'd expect a bumpy ride, right? The Coaster Roller dispels that notion with a surprisingly smooth glide over lumpy, acorn-shaped objects. Because the acorns have a constant width, the overall effect ends up smooth like a sphere, rendering their oddball shape inconsequential. Makes you rethink how shapes and curves actually work -- together, as it turns out sometimes.
