in this post: photos of the longest tobogganing tour ever, some more impressions from university, and one of those sets that can only be summarized as “misc”.
* about the coca cola photo:
coke has a pH-value of about 2.5. that makes it more acidic than vinegar (about 2.5 times more acidic), and about 10 times more acidic than orange juice.
it’s said that saliva and gastric acid quickly neutralize coke, but imagine how much sugar you need to make something so acidic taste sweet!
i first heard about it last october, and in a way, i’m still astounded…
