 | Before dusk, face the sun as it nears the horizon. Notice how you assume that it is sinking. Remind yourself that this downward motion is an optical illusion. |
| Drive an imaginary stake through the sun and pin it to the sky. Make sure it doesn’t budge. |
| Now watch the horizon climb gradually toward the sun. Imagine the ground shifting under your feet. |
| Give in to the feeling that the Earth is tilting backward in slow motion. |
| As the sun disappears, visualize your side of the planet rolling quietly into the night. |

Congratulations! you have just completed a 10,000 mile/hour backward somersault! |
