What made me start bubble was a state of emergency (order to refrain from going out) due to the coronavirus epidemic. To keep my two-year-old son from getting bored, I bought a small soap bubble electric toy (a bubble gun for about $ 3). My son's reaction was so good that I started searching the internet for various ways to play soap bubbles. I saw a news article that an American university (Emory University) found the most rational way to make giant soap bubbles, and decided to try this. It was a guar gum recipe, but the result was miserable. (Later, I found out that Japanese baking powder was the cause of the failure.) I was frustrated and searched websites around the world for soap bubble information. (I didn't use SNS at all at that time, so I didn't even know that there were bubblers in Japan.) And finally I found a soap bubble wiki. I saw amazing archives... After that, I had the opportunity to see wonderful bubblers from all over the world through the forum. Currently, I do simple shows at nursery schools and other places, and am researching bubbles. (I'm not an English speaker, so I'm using Google Translate and DeepL. Please bear with strange sentences if there are any.)
