Travel a Lot Meet Both Rich and Poor

I travel a lot and meet both the rich and the poor, but nobody knows where I am going next. I’m invisible but you can see what I do. Who or what am I?

Wind (or anything blown by the wind). It moves all over, reaches the rich and the poor equally and no one knows exactly which way the next gust of wind will blow. You can’t see the wind, but you can see what it blows, like leaves or dust.

Ten Times Two is 0218

10 × 2 = 0218
20 × 2 = 1421
30 × 2 = 1632
40 × 2 = ?

2840.

This makes the first column the start of the Fibonacci series: 0, 1, 1, 2.
The second column is the even numbers: 2, 4, 6, 8
The third column is counting up by ones: 1, 2, 3, 4
And the last column is the answer in the first row in reverse: 8, 1, 2, 0.

Don’t ask what 50 × 2 equals. I have no idea. :)

Thanks to Jim for helping with the solution.

The Floating Cork

If a cork is placed into a glass of water, it will almost always drift to the side of the glass. There is one simple way, however, to get the cork to float in the center of the glass. What is it?

Water, the glass, and the cork are all that is required.

The reason that a cork drifts to the side of a glass is that it floats to the highest point. Since water “clings” to the glass, the highest point is around the edge of the water. To get the cork to float in the middle of the glass, all you have to do is fill the glass as much as possible. The water will form a convex shape above the glass, with the highest point at its center. This is where the cork will settle.
