Written by Elvina Lee Here’s a cool activity that’s perfect for a hot summer’s day! Create a curious pattern with water.

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!

The year is beginning to wrap up, and the summer holidays are in sight. 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!

Washing your hands is important, but how do you know if it’s working? Make some safe but gross glow germs to find out how well you wash!

Drop the ruler, watch for the jump… that’s the point of drop jump! Can you work out which matchbox tray the coin will fall into?
