Bad Pop Rocks

Cassie was taking two of her grandsons on their very first train ride from Dayton, Ohio to Washington, DC.

A vendor came down the corridor selling Pop Rocks, something neither had ever seen before.

Cassie bought each one a bag.

The first one eagerly tore open the bag and popped one into his mouth just as the train went into a tunnel.

When the train emerged from the tunnel, he looked across to his brother and said: "I wouldn't eat that if I were you."

"Why not?" replied the curious brother

"I took one bite and went blind for half a minute."

Ellsworth Huntington

Born 16 Sep 1876; died 17 Oct 1947 at age 71. American geologist, climatologist, explorer and geographer who studied the origin, distribution, longevity, and accomplishments of civilization. He particularly wished to understand why progress varied from times when human creative energies flourished to periods when they seemed to fade. He attributed this to three causes: climate, the quality of people, and culture. Climatic circumstances resulted in migration, which could either facilitate or obstruct the advance of culture.
