Sod the fillings. We used to get given the stuff to fiddle about with in science class How about that? A science teacher with a geeky sense of humour.His middle name was probably Dr Phibes but what fun we had messing about with it...chasing the little balls round the table,flicking it at unsuspecting peers...mouths agog at its metarmorphosing tendencies.Come to think of it,we probably managed to fill each others teeth as we took pot shots at open gobs.
And all along this stuff is dynamite...deadly as hell.Heavens..it isn`t even allowed to be transported on helicopters and the like..so how bad is it when straight after science we all go and eat our sandwiches.

And to top it all..when I became a teacher and fancied dissecting bulls eyeballs with my kids,the authorities had a field day tellling me all about the dangers involved with such a notion.
er...sorry? Mercury...eyeballs...mercury....eyeballs...mercury ?
Am still struggling to find the danger connection here.
Unless of course we can catch PD from an exploding eyeball...

Me thinks someone somewhere way back in my youth got their priorities wwrong. tut tut
