We are a manufacturer of educational materials for young children. We are currently looking for a superior bubble concentration solution that teachers can mix with water to create strong, long lasting bubbles. Ideally, the bubble solution would be in the form of a powder that teachers would mix with water. They may even mix it with paint to create beautiful paint bubbles to make art! Once the solution is mixed up, we have a number of wonderful activities to do with the resulting bubbles to demonstrate to younger children aspects of science and mathematics. Because the bubble solution will be used by children, it must be non-toxic and safe. Because we are mixing it up ourselves, we need the recipe to be fairly simple. I am eager to work on this right away!

Dear Sir or Madam, I have PhD in chemistry. I was running R&D lab in household chemistry and cosmetics for over a year. Later I was working as team leader in medicinal chemistry lab. Currently I work as freelancer providing articles, reviews and know-how from the fields like biology, chemistry and medicine. I would be happy to provide the information about the recipe for the bubbles. My experience says that powder form is not an advantage due to the problems in fast dissolution ad well as precise portioning. Not mentioning the fact that the most ingredients are liquid. Looking forward to your reply Kind Regards Chris

Hi I have an idea of how this can be made. Usually only soap is enough to make bubbles . But here you want to make larger and much more stable bubbles. I have a solution to this. I will give details on what kind of soap should be used . The physical and chemical properties of soap. The kind of stabilizers to be used. The kind of paints or colours can be used. Toxicity of the chemicals .Storage condition. Concentration/Composition of mixture. I will provide you with research articles and references etc. as a scientific proof and also tell why it works . I am looking forward to this fun and exciting project. Regards, Suyash Msc Biotechnology IIT Bombay.
