A great demonstration of series and parallel circuits at work...and they look better on the model than on a lab bench! Light emitting diodes do not use waste power as heat as much as light bulbs do so the battery will last longer.

A simple flip of a small switch hidden in the costume turns on the LEDs.

What did the audience think at the fashion shown? When the model came onto the catwalk and the lights suddenly went out, the crowd "ooh"ed and "aah"ed when the brilliant wings lit up and spread out.

Well worth the effort and another example of "just in time learning" leading to useful knowledge and skills. Well done Tina! (and thanks to the model too!)
