On the way to preschool, a doctor had left his stethoscope on the car seat, and his little girl picked it up and began playing with it.

Electric mineIn 1841, an underwater torpedo operated by electric current was described by its inventor, Samuel Colt of Hartford, Conn., in a letter to U.S. President John Tyler. The invention was a combination of Robert Fulton's stationary torpedo and Prof. Robert Hare's galvanic current. Colt proved his mines could sink ships with a demonstration on 4 Jul 1842 sinking the gunboat Boxer in New York Harbor, and another on the following 18 Oct which sank the 300-ton brig Volta. By 13 Apr 1843, He was called upon to demonstrate to the President and his Cabinet, and Colt blew up a schooner on the Potomac River by an electric main from a distance of five miles. |
