Create a Cereal Box Aquarium

This cereal box aquarium craft is a great one for encouraging creativity! Kids can choose how they want to decorate their aquarium, what coloured fish and what colours even! There are so many options and ways to build an aquarium. We would love to see how you make yours!

What you need

  • 1 large cereal box
  • Coloured cardstock or Construction Paper
  • Shells
  • Kinetic Sand
  • Light Green Pipe Cleaners
  • Googly Eyes
  • Turquoise Paint
  • Silver Paint
  • Stones
  • String
  • Fish Template (see below for template instructions)
  • Precision Knife (adults only to use)
  • Hot glue (adults only to use)
  • Scissors


1. First you need to trace a cut-out on your box.  We used a sharpie to make our lines and then used a precision knife (adults only) to cut out the center of the box.

2. Now paint the inside of your box a turquoise blue color.

3. Paint the outside of your box silver (to make it look like an aquarium).

4. Now you can decorate your aquarium however you’d like!

Here are the elements we added:

Kinetic sand as a background on the bottom. We didn’t try regular sand but regular sand would likely work too.  The kinetic sand sticks together and holds in place so it’s easy to work with. You could also use cereal like cheerios or a puff style cereal to make it look like sand.

Green Pipe Cleaners – cut some strips of green pipe cleaners and glue to the bottom of your box to make it look like seaweed.

Sea Shells – we used the sea shells to hide the bottom of the pipe cleaners. Add some sea shells wherever you think they will fit! These will need to be hot glued down.

Stones for the bottom of the aquarium. Stones will add some weight for the aquarium to stand up on its own.  Stones can be placed at the bottom or hot glued down.

Now it’s time to add your fish!

4. Print off this fish template to make these adorable fish for your cereal box aquarium.

5. Now cut out your fish template and use it to trace your fish shapes onto your colored paper. We used orange, yellow and red cardstock.

6. Glue on googly eyes to your fish.

7. Take a small piece of string and tape it to the back of your fish.

8. Now attach the strings to the top of your cereal box.

Now you have a finished cereal box aquarium. We hope you had as much fun making these as we did!
