  • First, like someone stated above, your stomach pH won’t be very much affected by the alkalinity. Basically, your stomach pH is very low, pH 2 is normal. Since pH is a log scale, you would need to make it ten times less acidic to get a pH of 3. Som slightly alkaline water solution won’t get it there, especially since the stomach fluid is a buffer which helps maintain a constant pH. Dilution will help more, depending on the volume of stomach fluid. However, your stomach will produce more acid to make up for it.

    Second, now you still have to get the pH of the whole body higher, which means raising the pH of the blood. The pH of blood is about 7,4 and it is also a buffer. You have 5 liters of blood, which get constantly pumped around the body. If there were something jacking the pH of your blood (via IV), your kidneys would remove the alkalinity again, right up to the point of kidney failure. This is where you die.






  • Long story, but TL;DR: These are the factory settings for most older combination locks.

    Feynman in one of his books explained that he picked locks as a hobby during and after WW2. So he knew how to pick locks, but his method for combination locks was not practical, basically a guessing game. At some point, a safe (I think installed on special orders by some overseer of the Manhattan project) was locked and no one knew the combination. So someone sent for a locksmith to open it. Feynman was hoping to find this locksmith, so he could ask him how to open such a safe. But, when he came to the room with the safe, the safe was open and the locksmith gone.

    So he did what any sane person would do; he found out the name of the locksmith, started following him around for a bit and ultimately bought him a drink in a bar. When he introduced himself the locksmith recognized his name, Feynman being notorious for his shenigans including lockpicking. So he asks the locksmith how to open this kind of safe, and the locksmith responds “no idea”. So Feynman asks if he had no idea, why did he take the job and how did he open it. Then the locksmith explains that he was just going to show up, make some noise and all that, and then explain that he couldn’t crack the safe, here’s my bill thank you very much. But since he knew that these safes were all deliverd from the factory with either the standard combinations 0-25-0 or 25-50-25, he tried those first and that’s how he opened the safe.

    Feynman found it baffling that someone had a big heavy safe custom installed for him, but was then too lazy to change the combination. He also went around the labs (where a lot of files realting to the Manhattan project were kept), and found out that quite a few combination locks on the file cabinets were still set to default.
