But mine is more complete (is that the word?).

what if you made an air flow to planets around a larg one can that not make a solar system make solids work to with gravity + a tool that can grab solids powders and liquids keep it frozen like replace when grabed can drag through liquids and light powders if you drag a 4x4 solid through a 1x4 solid gap it will deform to a line and reform on the other end. and back to the subject you need to frezze clay to keep it together
