Merry Christmas! Here’s our maths gift to you – a puzzle.

Have you ever got halfway through wrapping a present, and then run out of paper? Follow our foolproof method and discover the maths of gift wrapping!

String is floppy, so it’s usually a terrible thing to build a tower from. But this tower uses tension and string to hold itself strong!

Now is the perfect time to brush up on your paper plane skills! We’ve collected a few quick and easy designs for you to try, from a looping master to a super-fast dart with a twist.

This paper plane flies quite a bit like a regular dart. But its striking looks make it much more fun. Plus, you get two pairs of wings – front and back – that you can modify!

This is a fun design to experiment with! You can give the plane bigger wings to float more, or fold over the front edge to make the nose heavier. Make a few adjustments and see which modifications work the best.

This paper plane isn’t very fast, but with practice and adjustment, you can make it do loops!
