Glycerin makes stronger, longer-lasting bubbles, but corn syrup is often substituted in bubble solutions because it is cheaper. Can you find other substances around the house that can be added to water to make a bubble solution? If you try products such as shampoo or liquid hand soap, you can check their ingredients to see what might be helping to make the bubbles form. Already a subscriber? Sign in.

Sep 24, ECF Towers. Please post a photo of your bubbles. Nov 10, Occoquan, NoVa. Higher dilutions lower detergent concentrations generally have longevity increases due to the thicker bubble walls. If you are using a poor-quality detergent, it is possible that nothing will help except for finding a better detergent.
Both solutions pH-adjusted to 7. There was a considerable difference in bubble lifetime for bubbles about 2 feet in diameter or smaller.
However, in the somewhat breezy conditions there was no appreciable difference in bubble lifetime for bubbles larger than about 2 or 3 feet in diameter. In these conditions, the 2 foot diameter bubbles were not "wobbly" whereas 3 foot bubbles quite wobbly. The difference in wobbliness is due to larger bubbles having a smaller pressure differential between interior and exterior air pressure.
It is very helpful for mixing polymers but not so helpful for improving bubble juice. If a recipe calls for it, by all means follow the recipe, BUT , we would recommend also mixing up a batch of the recipe and comparing the two versions in the same session on a few occasions to see if there is a difference in performance. Glycerine is hygroscopic. For this reason, people assume that it will help a bubble hold on to its water. This is the case when there is enough glycerine, but this will only benefit the bubble when evaporation is the main cause of the bubble breaking.
It is useful for mixing many polymers because many polymer powders do not dissolve or clump when added to glycerine. In these cases, the powder can be dispersed into the glycerine and then mixed with water to avoid the clumping that occurs when the powders are mixed directly with water.
Glycerine can help some polymers remain in solution although that is rarely a factor with the most common bubble-making polymers, and we have not found it to significantly alter the stability of any of the recipes found on the wiki.
Good question. It is a question for which I do not have a definitive answer. One part of the answer is that detergent, water and glycerine has been around as a recipe since before better recipes were known. This recipe was around even when I was in middle school in the early s when the original Dawn was around.
I have no idea if glycerine helped a mix of water and that long long gone original version of Dawn it might have , but the recipe was around then. As a result, a lot of people knew about that recipe and so it achieved a certain folkloric precedence which has proven hard to overcome. It has not helped that some professional bubble artists have posted this suggestion on their web sites because they understandably don't want to share their trade secrets.
It should be mentioned that few of them are using mixes radically different from the ones you find documented here on the wiki with the exception of those that are using commercial mixes. The original notion that glycerine is a magic ingredient may well be related to recipes shared earlier in the 20th century by people using soaps and custom surfactant mixes.
Much of the early 20th century research about soap films was done with single surfactant solutions whose surfactants were concocted by the researchers who found glycerine usefulf for those surfactants.
The detergents that we use these days are quite a bit different and do not benefit from glycerine in the same way. Soap Bubble Wiki Explore. Popular Pages. Getting Started. Getting Deeper. Explore Wikis Community Central. Register Don't have an account? Slide a sock over the end that you cut.
Dip the sock in the bubble solution, and blow! Where to get the supplies:. You can find glycerin at most drug stores, or you can order glycerin from Amazon affiliate link. I also totally recommend ordering the plastic water transfer pipettes! We have used them for mixing colored water , coffee filter art , and a science experiment with disposable diapers. And I have another activity planned for tomorrow where we will use them again!
Hi everyone, it's my first go to see at this site, and paragraph is really fruitful designed for me, keep up posting these types of articles.
Thank you so much for take the time to share, I have a childcare and preschool program in my home and looking for this summer camp for my boys who are coming back to have the summer here they are now in second grade, great ideas. It's like you read my head!
