Warning

"Contents under pressure. Cap may blow off causing eye or other serious injury. Point away from face and people especially while opening" warned my ginger ale bottle. I had been looking for advice as to whether the bottle was glass or plastic. Wouldn't it be wonderful if someone could make plastic glasses feel like glass - slightly cool to the touch and with the right weight. Yes, yes, I hear you say, if one was going to replace glass with this substance - why not just use glass? I don't know "the" answer.
