Zip A Dee Doo Dah

Visit Tim's Toy Shop, at https://www.grand-illusions.com/ ________________________________________________________ The humble zip does not often get a starring role. but Tim has a range of items in his collection that show unusual uses for zips! Tim shows an adjustable tie based on a zip mechanism - a zip tie! A lanyard based on a zip... From Bali, a zip case for sunglasses. Undo the zip and it opens into a flat sheet! From a UK Trade fair, a zip purse in the shape of a fish. It is actually made from fish skin, and the zip enables you to open and close the mouth of the fish. Finally, a magic trick based around a zip. Two separate loops, OR one large loop OR two interlinked rings. August Ferdinand Möbius together with Johann Benedict Listing described the mathematics of this phenomenon in the 1850s, although images of Möbius loops go back to Roman times.
