i think it would be adorable to do something like this in a kitchen. have a chalkboard wall for kids, notes, to-do lists etc. add some cute lights and make a focal wall. probably on the side of the kitchen
The instructions said, "use a gal jar and a type of stand place the jar in the water on it’s side, let it fill with water(completely sbmerged) then tip it up slowly bottom up, and the fish can swim up into it if they want"
