This week my partner Rosie and I started our sci-fest experiment. We are testing how much bacteria is on make up brushes and sponges if you don't wash them. This week we have started using make up utensils and washing one but not the other to show howmuch bacteria grows on them. We are doing htis for three weeks and then we are doing an experiment using nutrient agar t show the presence of bacteria on the make up brushes and sponges.
It is really interesting and hopefully will be loads of fun and will teach us a lesson about cleaning our make up brushes. I'll keep you posted on how it goes!
