Talk:Shrinky Dinks

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, 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)

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. — Preceding unsigned comment added by User: (talk • contribs)

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)
 * I have a problem with "the plastic shrinks by about five-eighths" anyway. Confusion with shrinking to 5/8ths, especially. All kinds of meanings could be meant, or understood. Is it now 62.5% of original or 37.5%? Though the latter is close to a 1:3 new:old size. Still, could be worse. Could be "three times smaller"..!  149.254.248.83 (talk) 23:59, 5 September 2017 (UTC)

This should be made consistent. The original was 3/8ths (as edited by 69.113.201.156 (talk) at 22:43, 28 October 2007. "...the plastic shrinks into a much smaller (about 3/8ths the original size)...") Then it was edited to be "...the plastic shrinks by about 5/8ths and..." (as edited by Pgan002 (talk | contribs) at 04:00, 5 December 2007). This is less clear for sure. Since 3/8ths is very close to 1/3, and the official website uses 1/3 (and it's probably pretty approximate) that this article should go with 1/3 Ian TO (talk) 23:30, 31 August 2018 (UTC)

National Security Risk?
Via Slashdot, I spotted an article that mentions Shrinky Dinks: Researchers Crack Medeco High-Security Locks With Plastic Keys .. is this something that belongs on this page? —Preceding unsigned comment added by Gts75254 (talk • contribs) 13:46, 10 August 2008 (UTC)


 * It's a reliable source, relevant to the article. I say, why not? Wellspring (talk) 18:02, 13 August 2009 (UTC)
