Dunno about braking action Gate, but I heard a story that some years ago a group from the American Temperance society arrived in OZ for a series of town hall lectures on the evils of alcohol.
Opening night, packed town hall, the head lecturer was determined to make the point.
Walking on stage carrying a bag, you could hear a pin drop, he opened the bag and produced two clear glass jars which he placed either side of the lectern.
Reaching back in the bag he produced a bottle of water and poured it in one jar. he then produced a bottle of Vodka and poured that in the other jar.
With a flourish he produced a box from which he produced a large worm which he dropped into the jar of water, the worm swam around happy as Larry. He then took another worm and dropped it in the Vodka. Worm shrivelled up and sank to the bottom.
Triumphantly the lecturer asked the room "Ladies and gentlemen what can we draw from this demonstration"?
A voice from the back of the room yelled " If you drink alcohol you won't get worms!!"
