It’s the start of December, which means you’ve probably already cracked open the chocolate advent calendar if you celebrate Christmas. Whether you do or not, the Compound Interest Chemistry Advent is back for its fourth year and is a great way to get your daily chemistry fix!

While the calendar won’t be a complete revamp from last year’s, there’ll hopefully still be some surprises along the way for those who’ve followed along before. 

You can keep up with the calendar day-by-day here – you could even set it as your homepage for the month to get your daily chemistry fix!
