The bacteria was pretty big but the one with most was the two; that was ms.spains door knob and that had a lot of bacteria on it and also the stairs railing.
A (top left) was from the stairs railing
B (top right) was the tap waters button
C (bottom left) was someone's locker
D (bottom right) was Ms Spain's class rooms doorknob
We used four kinds of controls on a small piece of paper and the only one that seemed to work was the bleach
