The​ ​main​ ​question​ ​that​ ​I​ ​am​ ​trying​ ​to​ ​answer​ ​is:​ ​What​ ​ingredient​ ​can​ ​be​ ​added​ ​to​ ​a bubble​ ​mixture​ ​to​ ​make​ ​the​ ​bubbles​ ​from​ ​evaporating​ ​so​ ​quickly?​ ​According​ ​to​ ​some​ ​of my​ ​research​ ​the​ ​ingredient​ ​that​ ​can​ ​be​ ​used​ ​in​ ​the​ ​bubble​ ​mixture​ ​is​ ​light​ ​corn​ ​syrup, detergent,​ ​and​ ​or​ ​glycerin. Some​ ​of​ ​the​ ​unique​ ​terms​ ​and​ ​definitions​ ​that​ ​I​ ​am​ ​trying​ ​to​ ​explain​ ​is: ● Light​ ​corn​ ​syrup-​ ​syrup​ ​made​ ​from​ ​cornstarch,​ ​consisting​ ​of​ ​dextrose, maltose,​ ​and​ ​dextrins. ● Glycerin-​ ​ ​a​ ​neutral,​ ​sweet-tasting,​ ​colorless,​ ​thick​ ​liquid​ ​which​ ​freezes​ ​to​ ​a gummy​ ​paste​ ​and​ ​which​ ​has​ ​a​ ​high​ ​boiling​ ​point. Background​ ​Research This​ ​project​ ​I​ ​found​ ​isn’t​ ​originally​ ​my​ ​project.​ ​The​ ​person​ ​who​ ​developed​ ​this project​ ​is​ ​Sara​ ​Agee,​​ ​a​ ​person​ ​on​ ​a​ ​website​ ​called​ ​Science​ ​Buddies​.​ ​Sara​ ​Agee​ ​decided​ ​to study​ ​this​ ​because​ ​she​ ​thought​ ​that​ ​making​ ​your​ ​own​ ​bubble​ ​solution​ ​is​ ​fun,​ ​but sometimes​ ​the​ ​bubbles​ ​don't​ ​seem​ ​to​ ​work​ ​as​ ​well​ ​as​ ​the​ ​solutions​ ​you​ ​buy​ ​in​ ​the​ ​store. Sara​ ​Agee​ ​discovered​ ​that​ ​light​ ​corn​ ​syrup,​ ​glycerin​ ​and​ ​detergent​ ​works​ ​best​ ​for​ ​this project.​ ​The​ ​problem​ ​is​ ​that​ ​she​ ​didn’t​ ​reveal​ ​which​ ​of​ ​these​ ​three​ ​ingredients​ ​works​ ​best for​ ​the​ ​bubble​ ​mixture.​ ​In​ ​this​ ​project,​ ​it​ ​will​ ​be​ ​my​ ​job​ ​and​ ​responsibility​ ​to​ ​record​ ​and find​ ​out​ ​which​ ​amongst​ ​these​ ​3​ ​ingredients​ ​makes​ ​the​ ​bubble​ ​last​ ​more​ ​efficiently.​ ​Sara Agee​ ​discovered​ ​that​ ​detergent​ ​works​ ​best​ ​for​ ​the​ ​bubble​ ​mixture. Hypothesis My​ ​hypothesis​ ​is:​ ​If​ ​glycerin​ ​is​ ​added​ ​to​ ​the​ ​bubble​ ​solution,​ ​then​ ​the​ ​bubbles​ ​will last​ ​longer​ ​because​ ​glycerin​ ​is​ ​a​ ​thick​ ​substance.​ ​Adding​ ​this​ ​substance​ ​will​ ​make​ ​the bubble​ ​last​ ​longer​ ​before​ ​the​ ​bubble​ ​mixture​ ​evaporates. ​ ​Glycerin​ ​is​ ​a​ ​neutral,​ ​sweet-tasting,​ ​colorless,​ ​thick​ ​liquid​ ​which​ ​freezes​ ​to​ ​a gummy​ ​paste​ ​and​ ​which​ ​has​ ​a​ ​high​ ​boiling​ ​point.​ ​If​ ​I​ ​used​ ​bubble​ ​mixtures​ ​of​ ​different substances​ ​to​ ​make​ ​bubble​ ​solutions,​ ​then​ ​hopefully​ ​a​ ​bubble​ ​mixture​ ​that​ ​is​ ​made​ ​with glycerin​ ​and​ ​water​ ​will​ ​make​ ​the​ ​best​ ​bubble​ ​solution. Materials/Procedures Materials: ● Glass​ ​jars​ ​with​ ​lids ● Measuring​ ​cups​ ​and​ ​spoons ● Distilled​ ​Water ● Liquid​ ​dishwashing​ ​soap ● Glycerin,​ ​small​ ​bottle ● Light​ ​corn​ ​syrup ● detergent ● Pipe​ ​cleaners​ ​or​ ​bubble​ ​wand ● Stopwatch Procedure: 1. First,​ ​make​ ​your​ ​bubble​ ​solutions,​ ​and​ ​store​ ​them​ ​in​ ​clearly​ ​labeled​ ​glass​ ​mason​ ​jars.​ ​Use one​ ​jar​ ​for​ ​each​ ​different​ ​solution​ ​and​ ​label​ ​with​ ​the​ ​formula​ ​using​ ​a​ ​permanent​ ​marker. 2. Now​ ​make​ ​a​ ​pipe​ ​cleaner​ ​wand​ ​for​ ​each​ ​solution.​ ​Pinch​ ​a​ ​pipe​ ​cleaner​ ​in​ ​the​ ​middle​ ​and give​ ​it​ ​a​ ​kink.​ ​Bend​ ​one​ ​half​ ​of​ ​the​ ​pipe​ ​cleaner​ ​into​ ​a​ ​circle​ ​and​ ​twist​ ​together​ ​at​ ​the center.​ ​Repeat​ ​with​ ​the​ ​other​ ​two​ ​pipe​ ​cleaners,​ ​and​ ​check​ ​that​ ​all​ ​three​ ​circles​ ​are​ ​the same​ ​diameter. 3. Go​ ​outside​ ​and​ ​test​ ​your​ ​bubble​ ​solutions.​ ​Blow​ ​a​ ​bubble​ ​and​ ​catch​ ​it​ ​on​ ​your​ ​wand. Immediately​ ​start​ ​the​ ​stopwatch​ ​and​ ​time​ ​how​ ​long​ ​the​ ​bubble​ ​lasts.​ ​This​ ​will​ ​take​ ​some practice,​ ​so​ ​try​ ​it​ ​out​ ​on​ ​some​ ​extra​ ​solution​ ​before​ ​you​ ​start! 4. Repeat​ ​the​ ​experiment​ ​as​ ​many​ ​times​ ​as​ ​possible​ ​for​ ​each​ ​solution. Results Trial​ ​1 Trial​ ​2 Trial​ ​3 Detergent 7​ ​min​ ​29​ ​sec 3​ ​min​ ​12​ ​sec 6​ ​min​ ​37​ ​sec Corn​ ​Syrup​ ​+ solution 7​ ​sec 4​ ​sec 9​ ​sec Glycerin​ ​+ solution 2​ ​min​ ​19​ ​sec 1​ ​min​ ​5​ ​sec 3​ ​min​ ​39​ ​sec Discussion My​ ​results​ ​were​ ​detergent​ ​can​ ​be​ ​added​ ​into​ ​a​ ​bubble​ ​mixture​ ​causing​ ​the​ ​bubble to​ ​last​ ​more​ ​longer​ ​than​ ​it​ ​usually​ ​does.​ ​Adding​ ​the​ ​detergent​ ​to​ ​the​ ​mixture​ ​made​ ​the bubble​ ​last​ ​for​ ​about​ ​6​ ​minutes​ ​in​ ​total.​ ​The​ ​pattern​ ​was​ ​that​ ​on​ ​trial​ ​1,​ ​the​ ​bubble​ ​lasted for​ ​7​ ​minutes​ ​and​ ​29​ ​seconds.​ ​On​ ​trial​ ​2,​ ​it​ ​lasted​ ​for​ ​3​ ​minutes​ ​and​ ​12​ ​seconds.​ ​Last​ ​but not​ ​least​ ​on​ ​trial​ ​3,​ ​it​ ​lasted​ ​for​ ​6​ ​minutes​ ​and​ ​37​ ​seconds.​ ​The​ ​graph​ ​I​ ​created​ ​was​ ​a​ ​table because​ ​it​ ​showed​ ​a​ ​clear​ ​understanding​ ​of​ ​how​ ​each​ ​bubble​ ​lasted​ ​with​ ​different mixtures. Conclusion My​ ​hypothesis​ ​was:​ ​If​ ​glycerin​ ​was​ ​added​ ​to​ ​the​ ​bubble​ ​mixture,​ ​then​ ​the​ ​bubbles will​ ​last​ ​much​ ​longer.​ ​Detergent​ ​ended​ ​up​ ​lasting​ ​the​ ​longest​ ​because​ ​if​ ​you​ ​were​ ​to compare​ ​the​ ​thickness​ ​of​ ​the​ ​glycerin,​ ​detergent​ ​and​ ​light​ ​corn​ ​syrup,​ ​you​ ​could​ ​tell​ ​that the​ ​glycerin​ ​was​ ​much​ ​thicker​ ​than​ ​the​ ​others.​ ​Therefore,​ ​the​ ​detergent​ ​was​ ​so​ ​thick​ ​that it​ ​couldn’t​ ​evaporate​ ​fast.​ ​My​ ​hypothesis​ ​didn’t​ ​support​ ​the​ ​results.​ ​The​ ​glycerin​ ​came​ ​in second​ ​place.​ ​Maybe​ ​the​ ​data​ ​came​ ​out​ ​the​ ​way​ ​it​ ​did​ ​because​ ​bubbles​ ​pop​ ​when​ ​the solutions​ ​evaporate.​ ​If​ ​I​ ​were​ ​to​ ​start​ ​this​ ​project​ ​over​ ​again​ ​I​ ​would​ ​change​ ​the​ ​materials. I​ ​would​ ​exclude​ ​the​ ​light​ ​corn​ ​syrup.​ ​I​ ​don’t​ ​think​ ​the​ ​light​ ​corn​ ​syrup​ ​would​ ​thick enough​ ​because​ ​that​ ​is​ ​used​ ​for​ ​making​ ​thick​ ​foods​ ​like​ ​gravy.​ ​I​ ​would​ ​replace​ ​the​ ​light corn​ ​syrup​ ​with​ ​dishwashing​ ​soap​ ​or​ ​any​ ​kind​ ​of​ ​thick​ ​soap.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
