I developed this idea after the movie, because someone (Tony or Banner, I don't remember) stated that the jewel of the Scepter was some kind of container to something, later revealed to be the Yellow Gem of Mind. In my opinion, it's like a nuclear battery: You use some kind of equipment to drain it's energy without harm

The Scepter and the Tesseract are much more like weapons powered by the Stones than another forms. Also, in Thor's poolside vision, the Tesseract breaks to reveal the jewel, and, in some high-definition images, it's visibly that the Tesseract is made of a glass-like substance. Is only pay attention to the borders

The Orb was created only to hold the Stone inside it, nothing more

The Aether was, so long, the only one who appeared with another form, being originally solid and now liquid, but it can be returned to it's liquid form, as, in Thor 2, when Thor tried to destroy it with the Mjölnir, it break into several solid, shattered pieces of a single stone, before joining again and returning to it's liquid form

If the Soul or the Mind had another forms, is unknown, and the reasons are obvious. If Soul is with Adam Warlock as everyone think, so it is probably in the normal state. The hard one is Mind. It can be normal, locked, weaponized or in another state
