My Invention

My invention to make the world a better place would be markers that don’t make that annoying noise that some tech lit. teachers like to make. I don’t know how I would do it, but I’m sure that a scientist could help me figure out how to make it. The reason why I want to invent that is because some immature teachers like to take their markers and make a super obnoxious nosies with them, taking the class of task and make a weenie out of himself. One other good part about it is that some nerdy computer teachers are always telling us to be quite, but are here making there own noises.
