The Mobius Band Band

Flat Stanley, Flat  Arthur, and I made Mobius bands. Together we are the Mobius Band Band! A Mobius band is made by paper and tape. You cut a strip and then put the ends together but before you tape it you have to give one end a half twist. If an ant were to crawl along the length of this strip, it would return to it's starting point having crawled across every part of the strip without ever crossing an edge. This is neat because if you have an odd number of twists then you have one boundary but if you have an even number of twists then you have two boundaries. The Mobius Band was discovered by the German mathmaticians August Ferdinand Mobius and Johann Benedict Listing in 1858.
