Cookie...my son is doing the science expierment... where u grow bacteria from a dogs mouth and a humans, to see which is cleaner. It says I need agar. I dont have any science stores near me. You have any suggestions? Thx Gloria

My son is in the 4th grade this year and doing a science project. We were thinking of doing the expierment where you grow bacteria from a dogs mouth, and then from a humans mouth to see which one has more bacteria in it. Anyone have any ideas, how to help make this a success. DO i need AGAR, or can i make it myself? Thanks alot to all who reply!
