1. Mugs must be able to contain at least 500 ml and not more than 625 ml of liquid, and be useable for drinking purposes. Mugs must not decompose when they contain a liquid.
2. All mugs must have a serviceable handle(s) which permits gripping and retaining a mug filled with at least 500 ml of liquid.
3. Mugs must be made entirely from ceramic or glass materials, and may not contain any metal, plastic, paint, organics, or nonceramic materials.
Knowing these requirement I think we designed an awesome mug, I may be a little bias. Now I can't wait until we finish dropping these things so I can upload a video of me throwing my mug to the ground. Until then here's a link of a guy that maybe shouldn't throw so many thing to ground.
Disclaimer: This video has nothing to do with ceramics or science communication but whenever I think about the mug drop contest this video pops in my head.
