A New Spray That Detects Exposure to Poison Ivy

When I was in seventh grade, my parents took my six siblings and I out of school for a late spring vacation to the East Coast. We camped along the way and eventually landed in a Virginia campground that had great trees for climbing, thanks in part to the vines winding up their bases that made ascending easy. Climbing was a blast, until I fell head first off a branch, about 15 feet to the ground. I put out my right arm for protection and broke my humerus just beneath the ball when I hit. An ambulance showed up and a paramedic asked if I had moved since I fell. I hadn't. Then he pointed to the vines at the base of the tree and asked if I was allergic to poison ivy.
