Here our Jellyfish, its hollow and prints great. When you put a Air Plant inside it to give it a complete air jelly look. Looks cool hanging in our living room window. Our cats love to sit and stare at them for hours on end. These fun hanging jellies brighten up any room! Hang them inside or outside. We use many kinds of Air Plants. This particular plant is called "Tillandsia". They have no stems, they have no roots, and their leaves don't look anything at all like leaves and they require no soil at all, either, and don't live in the ground. They still need some water, we just put some distilled water in a sprayer and give it a good mist, a few times a week and should be good to go, in the right sunlight and conditions.' You can find other species of air plant to fit your Air Jellies. Shop at some online nursery.
