SideBlog: Rainbow Cocktails by Doug Winship 27 September science Sideblog Nine differently colored drinks poured from the same shaker. Some serious chemistry at work here, folks. I wonder if they’re actually potable. (video) Related 1 COMMENT Add Comment Tony Harion 28 September Reply I ran across this video a few days ago. Seems that they mix a screw driver kind of drink, ice it up and shake. After they add to the shaker a healthy dose of grenadine (which will sink) and a good portion of blue curaçao (which needs to float*). Don’t stir it anymore, not a bit. Just serve and density will do the rest. We did a “careless, just for the hell of it” test and it worked pretty much the same. *For it to work better we added some vodka to the curaçao to help it float. Not that great of a drink but the idea is interesting. Tony Harion(Quote) (Reply) Click here to cancel the reply Your email address will not be published.
