It must almost be holidays for everyone and so it's nearly time to celebrate! For many people that involves having a nice cold glass of something and we have found the very best way to open a bottle – a beautiful Klein Bottle Opener from Bathsheba! We love Klein bottles, just one of many beautiful mathematical surfaces. You can read all about them while you enjoy your glass of bubbly!

Merry Christmas from all of us here at *Plus*!
