Did you know that you can find bubbles in a lot of other liquids beside detergent? The London-based firm of A&F. Pears painted a picture of a child playing with a bubble in 1886. The Chicago company Chemtoy than began selling bubble solution in the 1940’s. I have been wanting to do this science fair project since the beginning of summer. One day I was outside playing with bubbles when I wondered if anything could be added to a bubble solution to make the bubble thicker, so it would last longer. I then knew that I could do a science project on it in 7th grade. My overall question is how does corn syrup or glycerin affect your bubble solution compared to bubble solution you can buy?How does glycerin work with bubbles? Glycerin makes the bubble solution thicker.
According to www.homesciencetools. “The thicker outer skin of a bubble with glycerin keeps the water from evaporating as quickly, so the bubbles last longer. Glycerin also makes the bubbles stronger, so the bubbles will be bigger.” According to sciencing.com “a bubble pops when the water that is trapped between the layers of soap evaporates.” When you try to make a bubble with regular water you will figure it out that it does not work very well. This is because the surface tension of water is too high. Www. homesciencetools said that “adding detergent to the water lowers the surface tension, creating better bubbles.” Adding glycerin to your bubble solution can help it in two ways. One way is that the glycerin helps to keep bubbles alive longer. The other way is that it makes the bubbles more flexible. Adding glycerin to your bubble solution will take the number of water molecules at the surface down. Therefore the evaporation takes slower because the bubble solution has glycerin in it.
According to soapbubble.dk.com “the water from the surface disappears from the soap during the evaporation process. The molecules of glycerin attract water molecules and form a weak chemical bond. This weak chemical bond is called hydrogen bonds.” Hydrogen bonds make it harder for the water to evaporate, this happens because the glycerin pulls the water back into the soapy film. Soap bubbles will then have a longer life span.What are bubbles? According to www. homesciencetools. “Bubbles are pockets of soapy water that are filled with air. When soap and water combine together and air is blown into the combination, the soap forms a thin layer and traps the air, creating a bubble. Soap bubbles are not the only kind of bubbles. You can find bubbles in a lot of liquids. You can see small bubbles in water, they will always be in the water, or floating on the surface, but not floating through the air. Did you know that there are bubbles in soda pop, too.
The special thing about soap bubbles is that that they can float freely in the air; they do not have to be touching another liquid of water like most bubbles do.” Soap makes the surface tension of water not as strong as it usually is. It also forms a very thin skin that is more bendable than water. When air gets trapped under the surface of the combination of soap and water, the bendable skin stretches into a circular shape, to form a bubble. According to Www.homesciencetools “when you dip a bubble wand into bubble solution you can see the flexible skin of a bubble. When the wand is pulled out of the bubble solution, the hole in the bubble wand will be contained with the flexible skin of liquid. If you blow gently on the flexible skin you will blow a bubble.” When two bubbles meet they will join with each other and become one big bubble. The definition of a bubble according to dictionary.com is “a nearly spherical body of gas contained in a liquid.” What is in corn syrup that makes a bubble?
According to www.sciencing.com “the ingredients in corn syrup are not what make it a good addition to bubble solution. The physical properties, and the way the combine with water and soap make corn syrup great for bubbles.” Corn syrup does the same thing as glycerin, so adding corn syrup to your bubble solution is almost the same as adding glycerin. Corn syrup is very thick and stretchy, making the bubble solution good for strong and thick bubbles. Www.sciencing.com also said that “when the water gets trapped in between the soap/corn syrup the layers evaporate, then the bubble pops.” Why does the bubble solution you can buy create bubbles? The key ingredient in every bubble solution is soap. When mixing soap and water together the soap molecules spread out into tiny bits. Those tiny bits are what bubbles are composed of. When looking at a bubble you are actually seeing a tiny bit of air trapped inside of a thin film that is composed of two layers of soap molecules. When using bubbles bought from a store think of how many tiny particles of soap are in that one bubble.
In conclusion, I think that glycerin will make the bubbles stronger, so the bubbles will stay longer. I think this because glycerin makes the bubble solution thicker. According to www.homesciencetools. “the thicker outer skin of the bubble with glycerin keeps the water from evaporating as quickly, so the bubble lasts longer.” Glycerin also makes the bubbles stronger, the stronger the bubble the longer the bubble lasts. The answer to my overall question is that glycerin and corn syrup makes your bubble solution better because of how thick the bubble solution gets. The thicker the solution the better and stronger the bubble.
