sorry a mod showed me your post it was invisible on my side the forums have been a little glitchy for me recently.
No one has posted and it is my thread so to keep it going I just made this up; I am sturdy and white, Shiny and slick, Words come and they go, I teach but don't speak, I am but a tool for many, or even fun for Some.
That wasn't very specific lol. It is pretty much everything to do with sound or air lol More detail in the riddle next time please
