A group of third, fourth and fifth graders accompanied by two female teachers went on a field trip to the local racetrack to learn about thoroughbred horses and the supporting industry.
During the tour some of the children wanted to go to the toilet so it was decided that the girls would go with one teacher and the boys would go with the other.
As the teacher assigned to the boys waited outside the men's toilet, one of the boys came out and told her he couldn't reach the urinal. Having no choice, she went inside and began hoisting the little boys up by their armpits, one by one.
As she lifted one, she couldn't help but notice that he was unusually well endowed for an elementary school child.
"I guess you must be in the fifth," she said.
"No ma'am," he replied, "I'm in the seventh, riding Silver Arrow. Thanks for the lift anyhow."

Flotation process patent

In 1898, English brothers Alexander and Francis El applied for a British patent (No. 21,948) for their flotation process to separate valuable ore, such as copper, from the gangue (worthless rock) with which it is associated when mined. It was the first practical equipment to extract metals from low-content ore. Pulverized ore is mixed with water and brought into contact with thick oil. The oil entraps the metallic constituents, which are afterwards separated, and gangue passed away with the water. Today, flotation methods remain vital in the mining industry, processing millions of tons of ores each year.
