    Unlike the usual 3-component Borromean rings, The _Borromean Olympic rings_ do *not* have the property that if you make one of the rings disappear, others will fall apart. For that property, you need to look at *Brunnian* links.

    Poor Borimir from LOTR. He only wanted to use Frodo's ring as part of his hobby for making Borromean rings - they are named after him after all. However it all came across the wrong way and it ended up looking like he was trying to steal the ring and then gets himself killed before he has a chance to properly explain himself... :(

    This video is almost 5 years old, but I don't see any comment pointing out that the supposed Olympic Borromean ring is wrong. The basic principle is that the removal of any one ring causes the whole thing to fall apart, but the example here works as long as you keep any 3.

    I made some Borromean rings out of rubber bands, and realized that's the best way to show them to people. Ask them which two are connected, and regardless of which two they say, just grab them and pull, and they'll separate with a significant gap, but be held together by the third. You can alternate which two you're holding and quickly show someone that no two rubber bands are connected.

    in knot tying, the boromean rings are classified as n bight, a*n lead turks' heads, where a and n are whole numbers. the # of bights is the number of loops around the outside, and the leads are the number of strands in the cylindrical forms' cross-section

    The end of that video reminds me of middle school and when everyone was obsessed with drawing s's in a braid style. 3 lines on top, 3 on bottom, 2 in the middle, and then finish with a V underneath and ^ on the top side. Or you could just draw them endlessly on your teachers desk of course. :D

    Looking at my gigantic 7x7x7 Rubik's Cube (actually it's a V Cube but whatever...) sitting on my nightstand, I keep wondering about the mathmatics of it all. I would love to see a video on this. A 3x3x3 cube would work fine too, but the big one is a lot more facinating. I keep coming up with new ways to make both symmetric and asymmetric patterns. The way everything works together in a VERY spesific pattern, yet still allows me to do basically whatever I want with it keeps blowing my mind.

    I want Borromean wedding rings too. My fiance loves the math part, & I love the symbolism that the rings cannot be separated (& also how unique they are). The jewelers have tried several times now, but they can't seem to make them correctly. They claim the rings won't lie flat, & won't be able to be worn on the finger, if they can make the pattern at all. The only reason they won't say it's impossible is because I showed them this video. If the professor here can make them, surely professional jewelers can.

    when I was in middle school I would draw rings like that and on a standard sheet of paper I could link 9-10 rings together on my spare time after I finished my math worksheet. I also figured out how to rig up a deck of playing cards so if I had 2-5 people playing poker I would have the highest hand and win all of the nutty butty bars, that is what we used instead of real money (only cost .25 at the lunch line)

    @numberphile -- Food for thought,,, A Borromean 5-ringed Olympic symbol may perhaps better reflect what the Olympics *should* be, but I wonder if the current symbol more accurately reflects the Olympics in reality -- a loose affiliation standing together regarding sportsmanship. A looser affiliation may also symbolize more adaptability, diversity, and less rigidity than five very-tightly-woven Borromean rings. It's not as loose as a mere chain, but more like chain mail.
