Turn a shoebox into a Viking longship with a real sail, then test it in the bath.

A sail only works if it catches the wind. Testing yours in the bath teaches that in minutes.

What you need

  • A shoebox or plastic tub
  • A straw, stick or pencil for a mast
  • Paper or fabric for a sail
  • Tape and a bowl of water

How to do it

  1. 1

    Tape the box seams so it holds water out for a few minutes.

  2. 2

    Stand the mast in the middle, held with a lump of tape or plasticine.

  3. 3

    Cut a square sail and thread it onto the mast.

  4. 4

    Float the ship and blow gently, or fan it, to move it across the bath.

  5. 5

    Add small stones as cargo until it sits low, and count how many it carries.
