73, if you go by Kaye's conclusions with the rubber bands. the money couldn't of been in the sand soon after the crime. there would be no signs of the rubber bands what so ever after several years in the elements.
Kaye's statement(s) about how bands age is confusing, and incomplete. In order for there to be some remnants of the bands visible on the money, and stuck to the cotton fibres, one of two possibilities exists both of which involve chemistry of the bands and some set temperature range. It's not enough to say bands age in six months, or bands are this or that in six months to a year ..... you have to explain how rubber band chemistry works. The Ingrams said the bands were intact and crumbled to the touch, and pieces of the bands were stuck to the money. Pieces of bands had to be plucked off the bills and some pieces pulled money fibers with them.
There are to general conditions possibilities: (a) the bands went through the glass melt transition phase (a technical term) and turned gooey and flowed in amongst bills fibers. Problem is that requires a minimum of 69F degrees. This type of process must normally happen when bands are still young and viable within six months of being exposed to nature. (b) The more likely scenario is long term molecular depletion and crystallization which generally occurs below 69F degrees and given enough time can even occur slowly in temperatures near 32F degrees.
B is the more likely scenario imo, because the Ingram said the band (crystals) crumbled and turned to dust when touched. That sounds like soft crystals crumbling to the touch. The B scenario also requires more time vs A. A requires higher temps. And it could be a combination of A and B!
But, Tom's tests and statements about how and when bands age (within six months) leaves out the whole reality of what rubber band chemistry is and how it works. Rubber are their chemical makeup! Bands can only do what their chemistry allows them to do in different temperature ranges over different stretches of time. Kaye's "six months" is a statement about band chemistry without stating the actual chemistry at work, and Kaye know it!
So why not frame in terms of the chemistry at work, in the first place!???
