Simple Halloween 'Watching Eyes' with LEDs

We're having a Halloween party around my place, which is mostly taking place outdoors.  I thought it would be cool to have some glowing LED 'eyes' watching from the bushes and trees around the party, so I did some googling and came across LED Throwies.  They're kind of cool, but I wanted to have two LEDs running off one battery, and have them sufficiently far apart that they looked like glowing eyes from a distance of a few metres.

So, I came up with these 'Toilet Roll Terrors', or Bog Roll Bogles, if you're from my part of the world.  Essentially, it's two LEDs forming a simple circuit centred on a 'coin slot' for the watch battery that powers the whole thing.  It's all put together with tape, garden wire and a toilet roll.

Read on to see how they're put together.

Step 1 You Will Need

To build a Toilet Roll Terror, you will need:

- One standard toilet roll inner tube
- a roll of black electrician's insulating tape
- One Lithium CR 2032 watch battery
- Two coloured LEDs (red or green works best)
- Two five inch lengths of garden wire, with the plastic casing stripped off
- A craft knife
- A pair of pliers with a wire stripper
- Scissors

You can do this without the craft knife and pliers, they just make it much easier to cut, bend and trim things as you go.
