A father gathered his three sons and told them he would die soon and needed to decide which son would inherit his land. He gave them the following test.
“Go to the market and purchase something that is large enough to fill my bedroom, but small enough to fit in your pocket. Based on what you bring I will decide which of you is wisest.”
All three sons went to the market in search of something to satisfy their father’s demands. When they returned the father gathered them in his bedroom.
The first son put down pieces of cloth that he had bought and laid them end to end across the room, but it barely covered any of the floor.
The second son laid down hay but there was only enough to cover part of the floor.
The third son showed his father what he had purchased and the father announced, “You are truly the wisest and will inherit my land.”
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.
A man dove into the water with no tank, snorkel or any other device to allow him to breathe, yet he stayed down there to live for the rest of his life. How is this possible?
Smoke. It rises then slowly dissipates in the air. Smoke signals send messages and incense is used in religious ceremonies. Anyone who’s sat at a bonfire knows smoke in your eyes can make you cry when the wind changes direction. Smoked meats are a tasty treat, but if you see heavy smoke (i.e. from a fire) then run. Or stop drop and roll if the fire already caught you.
