泡沫的韌性有多強 洗碗精+膠水+糖+水經過攪動會產生夢幻的彩色泡沫但是都很快就破滅；因此作了一個小實驗到底泡沫的韌性可經得起水滴幾次的快速的衝擊而不破哪?過程；水滴在80cm高處落下穿過泡沫(未破)反彈再撞擊第二顆水滴炸現開花 發現膠水及糖的比率越高韌性越強越不容易破裂(大約可經2次水滴的的撞擊) 而且時間也越久不破

How strong is a bubble? Dishwashing detergent + glue + sugar + water, after stirring, will produce dreamy colourful bubbles, but they will soon burst; therefore, a small experiment was conducted to test how many water drops can the bubbles withstand under their rapid impact and not burst. Process: water is dropped from a 80cm height and bounces through the bubbles (unbroken), and then a second drop of water hits, they explode and slash. It is found that the higher the ratio of glue and sugar, the stronger the bubbles and the harder it is to break (can endure approximately 2 times of impact). And the longer time it can last.
