Joe's company designs and sales water pumps. Joe distributes the pumps through Mark's company, Beaver Pelt Distributers, Inc. Mark receives an order for a pump from Disney to install on the It's a Small World ride. Mark doesn't have the exact pump that Disney needs, but he decides to modify one of Joe's pumps to meet Disney's need. The pump ultimately arrives and is faulty because the modification made by Mark damaged the pump. The pump's failure causes $$100,000$ in damages to the ride. Is Joe liable for those damages?
