177o62 | Diluted red wine changes color at a certain concentration. What's happening here? | While doing dishes, I noticed that a couple of glasses containing 1/4 teaspoon or so of dark red wine did a nifty color changing trick.
If you slowly fill the cup with water, the red wine dilutes and becomes a barely detectable pink color. At a certain point, it seems somewhere around 6-10oz of water for 1/4 teaspoon... | askscience | http://www.reddit.com/r/askscience/comments/177o62/diluted_red_wine_changes_color_at_a_certain/ | {

54tixf | What is the current consensus on the Nixon administration's involvement in the Pinochet coup? | The CIA back in August declassified (but did not fully unredact) '60s/'70s-era presidential briefings to Nixon, including 9/11/1973 and 9/12/1973 for Chile.
Have the declassified documents revealed anything historians either suspected or did not know, even despite the still redacted portions?
