Bubbles are formed when an air pocket is trapped inside of a soapy sphere. Why are they only spheres? Even though many of the bubble wands are different shapes, bubbles can only form in a sphere because they are "minimal surface structures", which means that they shrink to the smallest shape they can be for the volume of air it holds. Why do they pop? Aside from landing on something sharp, they pop because the water between the soap films evaporates due to the sun. That's why when it's colder, bubbles tend to last longer because of the slowed evaporation process and sometimes will freeze. Why do bubbles stick together? Bubbles want to have the smallest surface area possible, so it will share a common wall with another bubble. If there are three bubbles that join together, they will meet at the center at a 120-degree angle! Where do bubbles get their colors? Bubbles get their colors from light waves reflecting between the soap film’s outer and inner surfaces. The distance between the layers gets smaller as the water evaporates, making the colors change. NOTE: I'm not a bubble expert! I got the information from: http://www.kidsdiscover.com/teacherresources/bubbles-for-kids/ Print Settings Printer Brand: RepRap Printer: Prusa i3 Rafts: No Supports: No Notes: Just download it and print it! No special settings are required! How I Designed This Using Tinkercad, I created all of these wands using simple shapes and holes. First, I had to come up with ideas of what I was going to create, and then I did it in the next few hours! But of course, I had to remake a few after printing and testing them!
