Bright spark creates cycling shoes with in-built fireworks

Firework season marks the time of year when it’s all too easy to get caught out without bicycle lights, so why not take inspiration from a DIY shoe modification that allows you to produce showers of sparks as will?

Instructables.com allows makers around the world to share building instructions for their wonderful, and sometimes weird, creations for free.

This particular idea works on the simple principle that when flint is dragged on the road it leaves behind a shower of sparks.

Another bright idea: Cycle insurance from 39p per week
