Ideas for sulpher cube

I think the Sulpher Cube has a lot of potential. If it could accept TNT, sponges, slime blocks, honey, maybe  dirt, (which you could then right click a hoe on the cube with dirt in it to get farmland in it) that would further do the point. Because The sponge I am really thinking could be good, if there is a sponge in it, it could suck up water, then maybe when it hits a wall the water falls out, the TNT I'm sure you could find out, slime would make it a lot bouncier than wood, honey would be sticky, farmland maybe you could plant seeds in it, but that would be more optional. I just think there are a lot of possibilities that I don't want to go to waste.
