A Lesson In Physics

(Our thanks go to the editor of the Australian Cartridge Collectors Association Journal for this story of a true Aussie bright spark.)

He had been told that a 303 bullet would stop in a foot of water. He was staying with relatives but home by himself.

A four gallon drum full of water in the bath; what harm could there be in that?

With trusty sporter in hand and one foot on each side of the bath he let fly.

Two gallons of water bounced off the ceiling, the light globe burst and the water in the drum kept going down.

There was a hole in the bottom of the drum. He lifted it up. There was a hole in the bath. There was even a hole in the floor underneath. What to do? Change out of wet clothes. Pack bag and relocate.

Some countries do hav'em.

Probably a graduate of the Australian Military , I suspect .....

Yeah those Army guys arn't to bright

True mate - I'm having difficulty stopping myself from offering a few names as to who the culprit might be , but that would be unkind to folk who live in the north-easternmost state of OZ...
