Floating fish

Here’s an idea for summer: transform walnuts into small, colourful floating fish!

You can make them easily with small children, using inexpensive materials that are available from any stationery or DIY store.

This is what you will need for the project:

  • walnuts
  • acrylic colours (or coloured nail varnish or enamel paint)
  • foam sheets in various colours and/or glittered
  • hot glue gun
  • googly eyes
  • pencil
  • scissors


Open the nuts, taking care to break them exactly in half (which will guarantee that the fish will float) and then empty them. Place a shell on a sheet of coloured foam and draw the outline. Remove the shell, then draw your fish’s fins from the shape of the shell, using your imagination and then cut along the edges of your design.

Put a little hot glue around the edge of one of the shells, then position the foam insert and, in the same way on the other side, glue the shell of the other half of the walnut. Make sure to press well to make sure that no water can enter in your fish.

Once the glue has dried (after a few seconds), you can colour your creation however your please, using nail varnish or enamel paint, acrylic colours, spray, glitter, etc. and, at the end, glue on the googly eyes.

With a basin full of water and a dozen or so little fish, you can organise a mini-fishing competition for small children and their friends!
