My son, Ben, and I were hanging around at Taman Sari Bali and I said I was thirsty. We sat near the pool drinking Orange Fanta, and I started to blow a note on the bottle. Ben tried, and failed. We tried again, and again, and again, and just at the moment I took this photo he sounded a note on the bottle. I think I was more surprised than he was.
Perfect timing, or dumb luck. Either way, it was fun.
