What it is: an ear explorer that allows you to see the wax inside your own ear. Date of invention: 2006; average cost: $459.36* I saw this ear scope on CNN, and I think it's a great idea for anyone who has trouble keeping their ears clean. The battery-operated Ear Scope TV is a confined endoscope that lets you view the video within your ear on a monitor. Any TV display can have the endoscopic footage connected to it using a standard connection.
