Right. You've made me do it. Tomorrow I'm buying Coke-Zero cans, chilling them, I will shake together, toss coin tap heads on the bottom, and open simultaneously (providing I can work out how to hold my phone and two cans at the same time) and will post unedited results on a youtube link. ALL I ask is whoever downvoted me, at least checks back. F'it - I really don't care. I've been an oppressed minority for so long it doesn't even matter. :) (I can't believe how wound up I'm getting over this - but baby-steps. I will build your trust until you elect me your benevolent dictator. It'll all work out in the end)
