Bubbles!
When I was younger, I like to play or blow bubbles! I even tried making the soapy solution in the bathroom when I have my showers. They never really worked and cannot be compared to the commercial bubble solution. It has been very long since i last played with them until last year when I had my elective.
Babies or young kids particularly dislike or feel uncomfortable when facing the doctors or nurses. The only way to make them comfortable or stop crying is to make them happy. The trick is to have stickers, lollipops and finally bubbles (especially to get the attention of babies!). Well, to distract the babies, the nurse or myself will blow the bubbles and they will just look in awe... That brings back my memories...
Trying to blow the biggest bubble or try to burst the bubbles my brother had blown. Even better if I can blow two bubbles at once... I just finished watching a video and somehow the lecturer started talking about bubbles (that is why I am writing all these). As a child, I do not have the curiosity as other children who likes to ask questions. I never wonder why the two bubbles (joined together) will become a single bubble later?
Today I have found the answer!
Basically due to La Place Law where pressure is inversely proportional to the radius.
Well, the bubbles usually have different sizes and the smaller bubble has smaller radius. So according to La Place law, the pressure in the smaller bubble is higher and therefore, will force the air to move from the smaller bubble to the bigger bubble to form a single bubble.
