• Can someone tell me more about the Borromean Rings?
• How did mobius strip get its name?
• August Ferdinand Mobius created the mobius strip, the one-sided shape that is featured in this video.
• I still don't understand. What is a freeze pattern?
• I followed the instructions for making the mobious strip but when i try to cut it it just turns into a big loop. What am I doing wrong!
• It's supposed to do that. But if you cut that big loop again, you'll get two separate Möbius strips. Well, that's if I remember right. I'll do it again, just to make sure.
• lets say we have a mobius strip. If you draw a line running down the strip, how come it comes out as a strip with a line on both sides?
• A Möbius strip is given a 180° turn, making one side flip to the other side, and, when you follow until the cut appears again, you find yourself on the original side. If you are really interested, watch Wind and Mr. Ug.
• So are Borromean Rings made from Mobius Strips?
• Dear Vi,
Could you make this video so that you eat it at the end?
• eat it eat it.
