Show THE POWER OF LITTLE THIXGS ' In a gun factory can be seen a . great bar of steel, weighing five hundred hun-dred pounds, eight feet in length and suspended by a delicate chain. Near-by Near-by is suspended a common bottle- ; cork by a silk thread. The desire is to see whether the cork can set the ; steel bar into motion. Such an effort 1 seems impossible. Let the cork be swinging gently against the steel bar, ( the steel bar remains motionless, but let it be done again and again for 10 minutes, and. lo. at the end of that time the bar gives evidence of feeling feel-ing uncomfortable a sort of ner- i vous chill runs over it. Ten minutes; later the chill has been followed by 1 vibrations. At the end of half an hour the great bar is swinging like the pendulum of a clock. Great possibilities are in that little lit-tle cork as held by the silken thread. American Boy. 1 4. |
