Genius !!Make your own. Use normal 14g silicone wire, black and red. Thread a metre length of heatshrink over it, wind it tight round a suitable diameter bar or mandrel and apply the heat to shrink the heatshrink. When you take it off, it will be a springy coil. QED.
Definition of an engineer. This is what they told me this on my first day at Glasgow Uni. "An engineer is a man that can do for a penny what any fool can do for a pound". The best engineer in our year was Fiona McDonald. She got 99% or 100% in every exam. The nearest to her were the Chinese in the low seventies. I don't know whether they changed the definition after that.Genius !!

There were only about 3 women on the course out of 300 in the first year. I guess things are a little different now. I think that went down to 2 out of 100 that graduated.
