Let's set the scene: 

It's Friday night, you dim the lights, light a few candles, put on some music... and boot up your Wii.

But only if you know that two candles can work in place of the Wii's sensor bar.

The Wii sensor bar contains two infrared LED bulbs that the controller recognizes to triangulate the positions between them. The only reason the sensor bar plugs into the Wii is to power the infrared bulbs. 

Because this is independent of the Wii system, you can easily replace the Wii sensor bar with household items like lit candles. 

Here's how to do it:

Place two lit candles roughly as far apart as the sensor bar is wide. In your Wii's settings, choose whether the candles are above or below the television just like you would for the sensor bar. Aim the WiiMote between the two candles and your pointer will respond on the screen like normal.
