Thanks!
I recommend you follow the poster on youtube in comment #1. That's where I learned about it.
You would do better to totally ignore ANY video from bpearthgrotch, er, watch..
As a source bpearthwatch (and his incessant videos) is a nutcase site that also will tell you about herculobus, niburu, sixteen foot tall aliens living in a cave in Arizona (or is it Nevada - well, it's out there according to this nutcase) and a logical rule of thumb says that if your source is skewed in one area there's a REAL good possibility that it is skewed in most (or all) other areas as well.
A bottle of water that is 'only' half methyl alcohol is still totally lethal...
Your mileage may vary.
For you alarmists out there, you should note that 2014 AW32 entered the Earth-Moon system at 1402 UT - 1102 EST - on 10January 2014. On 10 Jan. 2014 at 21:38 UT - 1638 EST, the near-Earth asteroid 2014 AW32 reached a minimum distance from the Earth of about 190,000 of km, that is just 0.5 lunar distances. No risks at all for our planet... At 0515 UT today (0015 EST - 11January 2014) it departed the Earth-Moon system. That means it was outta here twelve hours before this was posted... (Source for this info is in the links in the original post.. I note that bpearthgroth's video has been removed, but that is no real problem, it was not worth the time, unless you really want to manufacture doomsday scenarios and have another sip of the 'water'...)
Darksheare's coffee is better for you..
