Today will do another trick with a Mobius strip. Instead of cutting on the midline we will cut the strip at 1/3rd of its width. You will need paper strips 20cm x 3cm, glue, tape and scissors. Give the strip half-twist (180-degrees) and then glue its ends. Now cut the strip NOT AT THE MIDLINE but at 1/3rd of its width. Keep cutting without lifting the scissors. On finishing you will get one Original Mobius loop and another BIG loop. Isn’t it fun?
Take another strip and give it 2 half-twists (360-degrees) and then glue the two ends. It will look like a figure of 8. Once again cut the strip at 1/3rd of its width. You will 2 loops with the same diameter. But one loop will be double the width of the other. Now cut the wide loop once again into half without lifting the scissors. On finishing you will three interlocked loops, all with the same diameter!
