Teaching Vsper
It is great thing to teach VSEPR. Especially by using gummy bear. By creating jelly drop to be middle atom and using gummy bears as  attached atoms it  gives to student of every age how fun and tasteful can be learning. Make sure you get the wholesale size bag of candies....Students get all excited but they learn they really learn...
To show variable of the shapes just take away gummy bear  any way is possible...
