@timhutton@mathstodon.xyz just wait until your son discovers the belt trick https://youtu.be/rC0jAICfNwc https://youtu.be/Vfh21o-JW9Q https://youtu.be/vePEKN4wiHU https://youtube.com/shorts/yUw-jKApnIU These are like gateway drugs before getting into the good stuff like Brouwer's fixed point theorem or the hairy ball theorem or the Jordan curve theorem, or the Banach-Tarski paradox! You have some good times ahead of you!

@timhutton@mathstodon.xyz I did this in front of a school assembly when I was a kid. I don't remember how, and I can't imagine doing anything in front of a school assembly, but it worked. https://puzzlewocky.com/parlor-games/string-handcuffs-puzzle/

@timhutton@mathstodon.xyz if you raise the top band over and off the lip of the mug, both bands approach the gap in the handle from the right. steps to reproduce: - place band halfway through handle - take left half, pass the bottom of the mug through the loop - take right half, pass the top of the mug through the loop
