[edit] Chemistry

Would be nice to see some explanation of the chemistry behind the SD.

I agree. According to this instructables.com article, polystyrene, number six plastic. That shows it being done with blow-molded plastic, so I'm guessing it happens because of residual stresses from being stretched out. But I don't know. I'd like to see an explanation. —Ben FrantzDale 04:36, 4 January 2007 (UTC)

One relevant patent is [1], but that doesn't seem to be the base patent. The inventor is Betty Morris, who claims (on shrinkydinks.com) to be the originator. Jordan Brown 03:52, 21 January 2007 (UTC)

[edit] Family Guy bit

In the Family Guy bit, Einstein really doesn't kill God. There is no evidence of that in the clip. You can see it on YouTube in the Supernatural video on rabix99's channel.

[edit] Is it 5/8ths or 1/3rd?

The wikipedia page claims that the shrink ratio is 5:8, but the official Shrinky Dinks website claims it shrinks down to 1/3rd its original measurements (thus the "9 times brighter" claim, which makes sense; 1/3rd the length and width reduces it down to 1/9th the area of the original piece).

The video evidence provided on the site supports this idea, hence my request for clarification. Is the 1:3 ratio only for "Official" Shrinky Dinks (and thus the ratio varies based on which brands are used) or has this ratio changed over time? Veled (talk) 00:50, 9 June 2008 (UTC)
