How to tie your shoelaces is a good topic for a demonstration speech

Back in 2011 there was a three-minute TED talk by Terry Moore on How to tie your shoes that you can watch at YouTube. The Wikipedia article on shoelaces mentions that there are two common ways of tying them – the square knot or the less effective granny knot.

Although a lot has been written, there always is more to be learned. On April 11th there was a news article from the University of California at Berkeley titled Shoe-string theory: Science shows why shoelaces come untied. Back on September 23, 2015 there was another article at Gizmodo by Jennifer Ouellette titled What’s the best way to tie your shoes? Physics may have the answer. You can read the article she referred to about Untangling the mechanics and topology in the frictional response of long overhand elastic knots.

Special bubble laces like the New Balance Sure Laces shown above are one way to reduce the annoying need for re-tying.
