If you love maths and if you love puzzles this is a rainy day special for you. All you need is a highlighter or a red pen and you are off and running. Can you find the mistakes in Pi before the time runs out? Or, if you are feeling like you need help to fall asleep just run your eyes over the lines of pi and Sergent sleep will soon be along to whack you with a feathery pillow and help you to drift off to the land on nod.
