A Most Unusual Paragraph

This is an unusual paragraph. I’m curious as to just how quickly you can find out what is so unusual about it. It looks so ordinary and plain that you would think nothing was wrong with it. In fact, nothing is wrong with it! It is highly unusual though. Study it and think about it. You still may not find anything odd. But if you work at it a bit, you might find out. Try to do so without any coaching.

The letter “e” is the most common letter in the English language, yet it never appears in the entire paragraph.

How Can You Pass the Tree

A car is on a narrow road with a tree in the middle of it. How can the car pass the tree?

The tree is in the middle of the road as measured by length, not in the middle of it by width. In other words, the tree is growing on the side of the road, but it is equidistant from either end of the road, and therefore in the middle.

This makes it quite easy to pass the tree as you just drive on the road, unless you’re texting and you run into said tree. If this is the case, stop texting.

Thanks to everyone’s input on this one!

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.
