Sand under pressure could maybe displace certain solids and turn them into a powder form, where applicable, such as BMTL into BRMT, but just pressure does that. I'm not sure why it should dissolve the metal completely. Liquid equalization is something I have wanted since TPT was at unaligned. Surface tension is a good idea, would probably break some saves, and I'm not sure about the uses for it, but I do like the idea for it.
and by sand blasting I mean go rub your hand on sandpaper it is rough like a cats tongue not literally destroy the particle but turn it into dust form eg wood to dust bmtl to brmt, this would also have to work with too water like the steel cutting tools.
