2009 Ig Nobels are out!

The 2009 Ig Nobel Prizes are out! They celebrate research of questionable veracity or utility - you know, the stuff the Nobel Prize committee rudely ignores. My favourite study is the recipient of the Ig Nobel Peace Prize. They were awarded it for determining whether it is better be smashed on the head with a full bottle or an empty bottle in a bar brawl.



Are full or empty beer bottles sturdier and does their fracture-threshold suffice to break the human skull?

Beer bottles are often used in physical disputes. If the bottles break, they may give rise to sharp trauma. However, if the bottles remain intact, they may cause blunt injuries. In order to investigate whether full or empty standard half-litre beer bottles are sturdier and if the necessary breaking energy surpasses the minimum fracture-threshold of the human skull, we tested the fracture properties of such beer bottles in a drop-tower.

Full bottles broke at 30 J impact energy, empty bottles at 40 J. These breaking energies surpass the minimum fracture-threshold of the human neurocranium. Beer bottles may therefore fracture the human skull and therefore serve as dangerous instruments in a physical dispute.

So remember. If you're going to get in a bar fight, pick a fight with a person who's been drinking for quite a bit. Ooops! I originally said just started, but that'll get you glass shards in the brain.

Every bar-brawl type patron should read this. They think cus they see it in the movies they can smash a beer bottle over someone's head with no consequences. Haven't they ever heard of "sugar glass" that hollywood uses? Probably not.

Damn, too serious...

How's abouts telling them that it's just a total, unnecessary waste of beer!

Unless it is PBR, of course.
