Old picture, taken by my collegue David. Having fun at the pool at Saujana Resort, Kuala Lumpur. How to do this? In calm waters, lie still on your back, look up and make short but powerful burst of air with your mouth, like making farting sound (or if you know how to play the trumpet or similar, do that)
