Traffic Cone
The orange sentinel of roadwork that doubles as a party hat/Everyday Objects
The standard traffic cone stands 71 cm tall, weighs about 4.5 kg (with rubber base), and is made of PVC or rubber. Invented in 1940 by Charles D. Scanlon, a street painter in Los Angeles, traffic cones have become one of the most recognized safety devices in the world. They are also one of the most stolen objects on college campuses, frequently appearing on statues, rooftops, and the heads of inebriated students.
