500 Five Hundred!   January 8‚ 2018

This is where I say stuff

Well this is a double-special anniversary! The Petri Dish turns six years old AND we've reached the 500th comic at the same time!

To celebrate, I'm having a contest! Send me an email at johnmarksutton@gmail.com and tell me your favourite thing about the Petri Dish. I'll select the best entry, and that person will win a free copy of my latest book: "Stand Back, I'm Doing a Science!" Contest closes January 20th, so you'll need to email your entry before then. Flattery will get you everywhere, so butter me up!
