Hello my name is Erica and i am doing a science fair project to see what kind of facial cleanser works the best it being a natural remedy, pore cleansing pads, astringents, soap and water, or cream/foam cleansers. TO do this i have about 15 boys and girls that will not cleanse thei face for about 4 days and then they will press either their cheek or chin i havent decide which one into a petri dish. And several days later they will come back and test a product so on until all my products are tested. After each product is tested they again press their face into a petri dish. Then i will compare the amount of bacteria in the original to all the product petri dishes so i can determine which facial cleanser works the best. I have see lots of questions on your site regarding agar. What is agar, and do i need it in my project. If you could think of anything else that will help me in doing this project, it would be greatly appreciated. Please get back to me as soon as possible because the science fair is soon. thank you. Erica
