James Bruton of Southampton, UK, wrote in to share his dollar store (or 99p store in the UK!) Arc Reactor — it looks great!
Since I’m building an entire Iron Man suit, I decided that I should really build an Arc Reactor prop. This is intended to be like the Arc Reactor in the original Iron Man movie, since it won’t actually get installed in the suit. Pretty much all of the items I used came from the 99p store, with the exception of some wire and a few electronic components.
The items I bought are: an LED light with batteries, sink strainers, some pins in a circular holder, a solar garden light.
