Leaking roof???

This is an incident that happened quite a while ago. I just got the picture of the scene and I had to write it down. I will start from the beginning. It's quite long winded but bear with me. It's worth reading till the end.

Me and a bunch of friends joined a DOTA competition which was held within our hostel. Yeoh, Ah Boy, Jia Ming, Eugene and me signed up and went to compete. Even though it was a real damn small competition which only had 2 teams, we had fun pawning the opponent. So we won first place and the prize giving ceremony was held on the same day. At night, we went to claim our prize which was a hamper and took it back to Jia Ming's room.

All five of us gathered in the room and took some photos with the hamper. Inside the hamper were snacks, a bottle of sparkling juice and a few cups. It was nothing luxury but who does not like free food?(not really free though). The sparkling juice was something like a wine bottle. So Jia Ming wanted to open it at outside so it would not spill on the ground.

After a while....we heard a big "BANG" outside. Then our "smart" friend came in the room laughing with the bottle opened. "What happened?" i asked. He asked us to go out to look at the roof....After I saw the roof...I can only say one thing bout my friend...What a smart guy.. When he opened the bottle, he points it towards the roof not knowing it will poop out strongly. There was a big hole in the roof due to his "smart" action. I hope it does not leak during the rain HAHA. Here is the photo and the evidence too~~ Anyone wanna report him to our hostel's management? HAHA
