Seasons greetings to all. I first visited this site a few years ago, how much it has improved. Keep up the good work. (Did you know you can get bubble mixture which turns "gold" under UV light (may be good for night bubbles, but may be too dim for webcam to see)
（英语译为简体中文：祝大家节日快乐。几年前第一次来，这里进步真大。继续加油。（你们知道有一种泡泡液，在紫外线灯下会变成“金色”吗？也许适合夜间泡泡，不过可能太暗，摄像头拍不到。））
