"When you can measure what you are speaking about, and express it in numbers, you know something about it.
But when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind.
It may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the state of
Science,"
-- Sir William Thomson, Lord Kelvin, 1824 - 1907

If you have ordered in the past and want an additional kitlet, I will honor the "additional item discount" immediately.  Email me before placing your order.  Thanks!

Normally, this type of offering would be offered by our good friend Bill Kelsey of KangaUS.  Bill is still recovering from the flood in August 2007.  So in the meantime, we'll give this a whirl and see if we can help the builders out by offering the product ourselves.
