You can smash it with a hammer but it is self healing and will come back together as one again. It doesn't absorb dirt, the dirt remains on the outside and can be "cleaned" with a little time. It can shape shift into anything. You can separate it into many smaller balls and gather it back again, just like the UFO's.....just saying! Actually there is no healing per se needed because there is only separation not injury to the whacked mercury. That's even better.
(It's the vapors that will, over years of exposure, that will get you.) One instance of the words “that will” should be deleted.
( . . . many of it's its compounds . . . )
