Ever wanted to know why bubbles are round? Or how bubbles can help architects solve problems? A new exhibition at the Phaeno Science Museum in Wolfsburg, Germany, is taking the childhood pursuit of bubble blowing to the next level. An exhibition called BubbleMania will answer all those questions and more. Visitors will have the opportunity to blow giant bubbles, attend a scientific lecture on bubbles and watch a "bubble magician" at work, making necklaces out of bubbles and even blowing square bubbles. The exhibition opens on August 27.
