How To Make Bubble Water Blow The Biggest And Strongest Bubbles?

Update:13 May 2022

How to make bubble water blow the biggest and strongest bubbles? First, how big is the world's largest soap bubble? The current Guinness World Record was set in 2015 by GARY PEARLMAN, who successfully created a giant bubble with a volume of approximately 96.27 cubic meters using a giant wireframe immersed in a bubble solution. Let's discuss the chemical experiment of bubble water today!


Soap enthusiasts actually have a lot of experience with brewing bubble water before the researchers' scientific verification. Contrary to the advice of many small experiment sites, they point out that adding glycerin to detergent solutions is not obvious, and that the key to greatly improving the life of soap bubbles is something else: polymers that are easily soluble in water, such as melon. Soybean gum (commonly recommended dosage is 1.0-2.0g/L), or polyethylene glycol (bubble lovers often choose to add a product called "J-Lube", of which 25% is polyethylene glycol, usually 0.1-0.4g/L in bubble solution). Another experience these people have is that they "age" the powder containing polyethylene glycol for a period of time, saying it will make it work better.


First, the foam film did not get noticeably thicker after adding the polymer, but it did become noticeably less prone to breakage. The high polymer mainly changes the "extensional rheology" of the liquid film, making it more difficult for the fluid to break when stretched (this reflects the viscoelasticity of the polymer solution, imagine what the mucus looks like, almost like this).


Second, what enthusiasts call "aging" PEG for a while does work. In the experiment, polyethylene glycol powder was placed for 6 months. During this process, these macromolecules are degraded to a certain extent under the action of light and heat, forming a mixture of molecules of different sizes. Experiments have found that using this additive to strengthen soap bubble films works better, and the authors speculate that the smaller molecules create a degree of attraction and connections between the larger ones (though they haven't tested this). This effect can also be obtained by directly mixing polyethylene glycols of different molecular weights.
