Kelvin Goh (32): Well, after the Singapore polytechnic trip, the following Project Work lesson, the teachers drill us about the proposal of making a slor products. We suppose to think about ideas. Then, Soong Jia Min gave us lots of crazy ideas. The first examples is solar toilet bowl. She said that this product is good for cold countries. People who sit on it will get warmth. My group laughed. The following ideas are even more ridiculous. She thought of solar toilet paper, solar toilet basin.Can u tell me what can these do, especially the solar toilet paper. She dared to even say solar chocolate. The whole group laughed madly during the discussion,

Finally, we choose those reasonable ones that the group contribute.
