Students learned about inventors throughout history before taking to the drawing board and flexing their creative muscles to come up with their own inventions. Landon said he studies the work of British inventor Sir William Mills, who built the first effective hand grenade for use in World War I. Photo by Andrew D. Brosig/Tyler Morning Telegraph
