Thomas Edison
 One gloomy night, in Menlo Park
 Tom Edison said, "Gee, it's dark"
 But then he had a brilliant thought
 Electric lights would help a lot
 Now others too had tried their best
 To build a bulb that passed the test,
 And yet their light would never last
 The glowing part burned out too fast!
 Thomas Edison
 "I see," Said Tom, "I must invent
 A better stronger filament"
 At first he tried some metal wire
 Which melted, broke or caught on fire
 So next he tested strips of wood
 And every single plant he could
 He had them to char them first, he learned,
 To make them glow but not get burned
 Thomas Edison
 Grasses, reeds, and weeds galore!
 He tried 6,000 kinds, and more!
 He had some luck with cotton thread
 But then he try bamboo instead
 It filled the room with dazzling rays
 What's more, it lasted 50 days!
 And now, the light's golden glare
 Is seen in houses everywhere!
 New York and London! France! Brazil!
 They light the night when the day is done,
 All thanks to Thomas Edison
