Shrinky Dinks are a children's toy and activity kit consisting of large flexible sheets which, when heated in an oven, shrink to small hard plates without altering their color or shape. They reached the height of their popularity in the 1980s. Most sets are pre-printed with outline images of popular children's characters or other subjects, which are then colored in before baking. Shrinky Dinks were invented in 1973 by two housewives (Betty Morris and Kate Bloomberg) of Brookfield, Wisconsin, as a Cub Scout project with their sons.〔Doris Hajewski, "(Shrinky Dinks founder hopes to sell toy business )", ''The Milwaukee Journal Sentinel'', Oct. 27, 2008.〕 The first kits were sold at a local shopping mall and became very popular. Shrinky Dinks were soon licensed to be manufactured by the major toy companies of the time such as Milton Bradley, Colorforms, Western Publishing and Skyline Toys. The shrink plastic is still available from many retailers and can be used for anything from charms to pins. The base material consists of thin, flexible polystyrene plastic (#6) sheets. Prior to heating, the plastic sheets can be colored with felt-tip pens, acrylic paint, colored pencils, etc. and cut into shapes. However, oily or waxy substances (such as cheap colored pencils, crayons, or oil paint) are not suitable because they melt or burn in high heat. When heated with the Easy-Bake Oven, a conventional oven, or a heat gun, the plastic shrinks by about five-eighths and becomes thicker and more rigid, while retaining the colored design. Although Shrinky Dinks are primarily an arts and crafts product marketed for children, many adult crafters and artists find the product to be suitable for jewelry making and other projects. Blank sheets are available in bulk for this purpose, and Shrinky Dinks have, rather unexpectedly, become a serious artistic medium.〔(Shrinky Dinks becomes a serious art medium. Who knew? )〕 In 2008, University of California, Irvine Professor Michelle Khine applied Shrinky Dinks to create tiny structures for the application of microfluidics to topics such as stem cell research.〔 See also 〕 In 2009, an art therapy supervision class at Emporia State University explored the use of Shrinky Dinks in art therapy.〔Wolf Bordonaro, G.; Blake, A.; Corrington, D.; Fanders, T.; & Morley, L. (2009). Exploring media processes and products: Rediscovering Shrinky Dinks. ''Arts and Activities''. June 2009.〕 The group explored how to use and process Shrinky Dinks within art therapy settings. In 2014, Shrinky Dinks were presented as an art therapy media in a workshop at the American Art Therapy Association Conference.〔Wolf Bordonaro, G.; Stallings, J.; Miller, K.; Schreiner, L. (2014). Trailblazing with non-traditional media: The use of shrinky dinks in art therapy. American Art Therapy Association Conference 45th Annual Conference.〕 In 2014, a team from Harvard University and MIT used Shrinky Dinks to create self-assembling robots. In 1992, the California rock band Sugar Ray formed with the name "Shrinky Dinx", but later changed it upon threat of lawsuit from Milton Bradley. ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Shrinky Dinks」の詳細全文を読む スポンサード リンク
