Describe the Suggestion

The backtank could have added depth by allowing it to be filled with fluids and gases that are more interesting to manufacture or obtain than air.

Maybe if you filled it with steam your potato cannon will launch steamed-cooked produce
Maybe you could fill it with tea, turning the diving helmet into a liquid feeder
Or maybe even fill it with lava, making the extendo grip set mobs on fire

I don't think these ideas are that good (or make that much sense), but I wish there was a way for the equipment of create to expand and grow with factories of create, turning filling the backtank from more of an occasional annoyance to an opportunity for expansion.
