Much Fun with Stop Watch

1910

Owner Describes a Variety of Ways in Which He Has Found It Affords Him Diversion

"Having a stop watch," says the man who had just bought one, "reveals a whole lot of ways of amusing yourself that you'd hardly think of before.

"Since I've had a watch I've been able to while away a lot of time. Not a pun, either. For instance, walking in the city where the numbered blocks make calculating easy, I am continually holding the watch on my pedestrian efforts.

"I figure first how long it takes me walk a block. Going at top speed so that some folks think I'm mad, I have been able to do 88 yards in 29 2-5 seconds, or about seven miles an hour.

"Then, of course, I time all intermediate distances up to a mile. I've learned pretty well just what four miles an hour means, and I want to tell you that folks who speak so glibly about doing that ought to hold a watch on their performances to see what it means.

"The other day I got up some sprint races between some boys, just so I could time their running. I find there's lot of fun, too, in making imaginary bets with myself how long it will take me to catch up with some one else walking in the same direction or how long it will be before a car gets to a certain crossing.

"Also a stop watch is a great thing for timing how long you can hold your breath."

Blowing Bubbles is Fun

INTEREST IN SOAP BUBBLES

Those Made of Soap Water to Which Glycerine Has Been Added Are Quite Attractive.

Have you ever stopped to think what a really interesting thing a soap bubble is? Soap bubbles are not only interesting to boys and girls, but they have long been a source of and interest to men of science. In fact, scientists have employed soap bubbles in trying to perform certain experiments.

A soap bubble is nothing more than a film of water molecules (tiny particles that cannot be seen with the naked eye), held together by the sticking power of dissolved soap. As most all of us know, in making bubbles the bowl of a common clay pipe is dipped into soap water. The bubble maker blows air into the pipe and the bubble at once expands. While bubbles made of plain soap water are interesting, those made of soap water to which some glycerine has been added are even more attractive, because they have such pretty colors.

There are many ways of making bubbles. For instance, smoke may be blown through the pipe into the bubbles or one bubble may be blown inside of another. Very large bubbles can be made by using the hands instead of a pipe. Cover the hands well with suds and then hold them so as to form a cup, as if drinking with the hands from a spring, but leaving a small hole in the bottom. With the mouth about a foot from the hands, blow a current of air into them. Some of the bubbles will be more than a foot in diameter. Try this experiment the next time you wash your hands.
