i think that doing these experamints are really cool.by doing them,you can learn alot of things that you disn't know before.it's just like a thiller movie.you don't know what's around the coner.it keeps you wondering and thinking, what's going to happen next?that's why alot of kids do expermints. so if your sitting on the couch doing nothing,check out pbs kids.com!then do a experamint.but don't get the house dirty!

Because when you shake the jar verticaly the salt pushes the marble up and launches the marble when the salt falls back down, and the marble floats to the top when you shake the jar agian the marble gets a little bit covered because the salt bounces up and the marble has nothing under it so gravity pulls the marble down, and before the marble goes to the bottom the salt comes back and, holds the marble. and if you shake the jar verticaly agian and agian the marble sinks to the bottom.
