The Fun Theory

The problem is that sometime people go to the restroom and they donot wash their hand with soap. The solution is to make the soap machines fun. My soap machine have four buttons, you have to figure out which one is the one that gives you liquid soap. Every time you click in one of the four buttons and it doesnt give you the soap it will take out bubbles and make the sound bip and said it is wrong. If you click in the correct one it will give you the liquid soap and advice that why it is important to use soap and it will make more bubbles. The behavior will change because more people will wash their hands. Submitted by Vanessa Barcia
