Anyway, I actually got this idea thinking about a clock that had light coming out of its numbers.
I first made one a few weeks ago but it didn't really work, so I gave up. Then I was thinking about something to do with all the dowels I have, and after "playing" with them for a while I thought about trying again making some changes...and this is the result!
The dowels I used are the same ones that I used for the Spiral Lamp - 7cm (2.75 inches) long with a diameter of 5mm (0.19 inches).
If you don't have these, you can use different ones, paper straws or anything else you can think of. But make sure to adjust the measures in case your materials are different.
Especially for this lamp, I always recommend using LED light bulbs or at least low-energy light bulbs, especially the cold light ones.
