Can a penny dropped from a skyscraper kill a person below? Is it possible to "bake yourself" on a tanning bed? Did Lucille Ball expose a spy ring by hearing radio signals from her tooth fillings?

1) If dropping a penny from a very high building (like the Empire State) can kill a pedestrian.
2) If a tanning bed can kill you, burning your heart.
3) If metallic tooth fillings can transmit radio waves.
