First, if you want your aquariums to be night lights, attach light to the inside of the jar lid using E6000 glue. Set aside to dry while you build your aquarium.
Place plastic aquarium plant into the jar.
Use a spoon to add gravel around the bottom of the jar, covering the base of the plant.
Place figurines, fish, seashells and any other items to the jar.
If you would like your water to be blue, add a couple drops of food coloring to the water first and stir. Slowly pour water into the jar.
Screw the lid in place.
To turn on the light, carefully remove the lid, turn on the light, and replace the lid.
