Updated: Jun 3, 2020

Are you one of the parents whose kid's have been asking for a pet, you want to get them one, but you also know that they are too young right now for the responsibility. Fret not, these DIY mason jar aquariums will win your toddler's heart.

This STEAM project is not only suitable for toddlers and elementary students but also can be great for Art themed parties, school projects, or home activities with family. If your child is very young, use plastic mason jars and all steps need to be performed with the help of supervised adults.


  • Aquatic fish

  • Aquatic plant

  • 2 sided tape

  • Colorful pebbles

  • Tap water

  • Glycerine

  • Blue glitter

  • Gel stickers (optional)


1. Peel off the two-sided tape and stick one end to the bottom of the mason jar. On the other end, stick the base of the aquatic plant so that the plant stays in place.

2. Pour in the colorful pebbles to surround the plant inside the mason jar.

3. Now, you can peel and stick any gel-like stickers on the sides of the mason jar. This step is completely optional and your plant will look lovely even without it.

4. Fill the mason jar with tap water. Add your aquatic fish.

5. Add 2 tablespoon glycerine. Glycerine makes the water thick so that when you shake the bottle later all other contents move slowly.

6. You can now sprinkle some blue glitter on top. Close the lid tightly. Shake and enjoy!
