Which is why I use energy saver daylight bulbs. They have a blue light rather than yellow, a lot brighter,

Where do you get them from, I could do with one or two.

I find that using the EE bulbs is not good for my health or productivity, as some one who works either on a computer or with beads (small and where colour match is important) I find that the bulbs just do not give off enough light and so cause eye strain and headaches.

it might be the control gear which is causing the headaches rather than the colour of the lamp, although daylight lamps with better colour rendering are much nicer to work by

main frequency/switch start controlled lamp can have a slight stroboscopic effect which is linked with headaches etc.

generally in offices now people specify fluorescent lamps with high frequency control gear which reduces these effects.

When I was at school they gave you mercury to play experiment with, in Chemistry!!

yes indeed - we used to chase 'globs' around on pieces of paper making them join up and then break into bits again - great fun I recall. After that we'd go and drop some chemical into the loos (can't remember what it was...something carbide?), which gave off a gas, which we could then set alight thus burning the toilet seats (which were made of wood). If supplies ran short you could buy it in Halfords so it must have had some practical use. Those were the days (before H&S)!

I've got a puzzle that my wife gave me for Christmas about 15 years ago.

It is a completely sealed maze with a 1cm cubed blob of mercury inside. The challenge is to get the blob of mercury to the middle of the maze without [STRIKE]killing yourself[/STRIKE] splitting it in to smaller blobs.:eek:

They used to use carbide in bicycle lamps! basically, you placed it in the lamp, added water, set light to it and stuck it on your bike!

You could also drop some in a water-filled glass lemonade bottle, fasten the lid and run like stink! BOOOOOF!

Ahhhh...the good old days....

These days it would have to have the words "Harmfully if swallowed" printed on it.

Yep, those were the days when you could have fun.

Last year I found a web site about the village I grew up in, in the 60's. It had an article about an incident I heard about when growing up.

Two lads found a live hand grenade one day. They resisted pulling the pin and throwing into the school yard to see which kids were the slowest runners. Instead they decided to take it to the police station, which was at least two miles away.

Being smart they realised it might go off and kill them, so they took turns carrying it for a couple of hundred yards each, while the other one walked 30 yards behind the one with the grenade. That way if it did go off it would only kill one of them. To make the journey interesting they had a bet for which one of them would be carrying it if it did go off..

A few years later I remember standing on the street corner, being a few years younger than them, listening to them recounting the tale.

Kids these days just don't get the chance to idolise people like that when they are growing up.

I should imagine it would be harmful if swallowed, the puzzle is about 6 inches in diameter - imagine that going through, then coming out the other end :eek:

...thinking about it brings tears to my eyes...:rotfl:

I'll never look at it the same way again - THANKS!!!!

Now if you turned that experience into an X box game, erased the bit about it being in the UK and made it into an American tale from the hood then the kids may listen... :rolleyes:

I still have one of those games in my loft and thought it was great. Got mine in the early eighties.

As for it coming out the other end, it would be interesting to see if the game had been completed too. Now that would be a trick!
