When you pour a Guinness, or any beer with a dense, fine head; the liquid succumbs to gravity slowly as it tries to fall through the rising bubbles.

#6 Rockets are generally launched to the east, not west, to take advantage of the rotation of the earth. Less fuel is needed to get to orbit. Wrong direction, right idea.
At its closest approach, Venus is 38,000,000 km from Earth. At the rate of 2cm per year, the moon would begin to orbit Venus in approximately 2 billion years. That's significantly more than "a few million years".
