RogueTechDesigns

Hello, we are 3 seniors, Josh, Jeremy and Heath, from Niskayuna High School and were looking for help. We are all enrolled in a technology course called Engineering Design and Development (EDD) and in this course we must brainstorm problems, confirm they actually are problems, come up with some solutions, contact professionals in the field, and design and prototype our final solution. We currently have a problem and are working on our solutions, our problem is carbonated beverages overflowing when you open them shorty after they are dropped. We have begun research on the issue of carbonation and were hoping you could help us on how to control carbonation. One of our ideas was to add a screen that would only let the extra CO2 out but would not let out the beverage. What we are currently struggling with is finding a type of screen that IS FOOD SAFE but won't lets drinks through. Any ideas?
