defunct spark wheels

Canon EOS 6D - f/16- 25sec - 100 mm - ISO 200

 

- for challenge Flickr group: Macro Mondays, theme: Wheel(s)

- sparkwheels

- width of a sparkwheel: 1 cm

 

- The day I stopped smoking I removed all the sparkwheels from the lighters that were lying around in the house

 

- A spark wheel is made of serrated, hardened steel wire. When it is rotated with sufficient speed and force, it will strike a bar of flint within the lighter, creating a spark.
