you really shouldn't post this many element suggestions, especially not when you first start using the forums. The devs closed the element suggestions forum for a reason...

Define slippery, because in order for anything in tpt to be slippery (powders, liquids, etc) That would mean that they would need to move faster. That might be a large undertaking. That would require a lot of coding on the devs part for something that doesn't have very many uses.

most element suggestion threads get locked, the devs really don't need that many more new elements. They need to have a large number of uses to even be considered...
