lighters with coloured flames?

Just wondering how lighters with different coloured flames work. Like the one seen here

Any idea ? Is it the fuel or it just some light or something?

different compounds burn with different colour flames, its to do with the electron energy states. Copper burns green.

Yep. eBay has hundreds of em....

Very cool initially, but it get old quick.

so do they need special fuel? Or is it something built into the lighter?

Don't smoke - it's bad for you
but seriously, it's just a little food colouring, i remember back in the day, we bought about 20 food colouring bottles, and had a green bonfire - a complete waste of money, but it looked nice.

Nice one trickman :p
The best bonfire that I have had, was about 4 years ago or so, when it was raining, as always and we had to think of somethnig alternative to get our HUGE pile of branches and different objects burning, objects such as beds, tables etc : ) no worries, nothing bad like rubber or something.
Then we chose the best, gasoline!
Ohhh yes it was fun, we poured it into the hear of the fire and threw a match in, after about 1 second, the thing blew up :D
But it still burned nice : )
I still like the bestm the blue butane flame on my burner!

can we not get these from the store? i light inscense everyday...
