If you’ve not been keeping up with the posts, there’s still time to catch up for the last few days – head over to the calendar here! All of the posts are free to download as PDFs too, so you can print them out and use them to share some festive chemistry with your family or friends.

Though it certainly doesn’t match the production values of the ACS Reactions or Chemistry in Context videos, hopefully it’s still a bit of entertaining festive chemistry whilst you’re recovering from your Christmas Day exertions!
