Climbing up trees, you played jolok jolok assam, rounders and bola hamtam or hamtam bola they called it now. There is a lot. I forget what it is called, where you made use of a bicycle rim. You removed all the spoke. You used that wooden rattan stick to push the rim. I cannot remember the name. After you pushed the rim, you can raised the rattan stick. Some of the rim are thinner, some are thicker so it all depends. Its not just the rim, it is the speed on how fast you can move while pushing it without letting it dropped. These are my Singapore memories. (Memory Collected at the Yayasan MENDAKI's Learning Festival from 15 June 2012 to 17 June 2012, Singapore Expo Hall 5B).
