For today, here’s a quick update to an old graphic on the discovery dates of the different elements, rearranged to make it easier to print.

Ever wondered how much water/caffeine/alcohol you’d need to drink to reach a lethal dose? This graphic shows the median lethal dose for all three!

Read more detail about LD50 tests in the accompanying post: http://wp.me/p4aPLT-ol

That is all 100% bullshit.

According to this I should have died numerous times already.

If that were accurate I would die daily.

This is bullshit.

0.65 litre of 40% spirit is not a lethal dose - plenty people drink lots more than that.

.65L of 200 proof is not a lethal dose to someone used to liquor. And 6L of water? Hell… They tell you to drink that every day.

Not quite every day, but there are plenty days when I have drunk 6 litres or so, mainly because it was summer and I sweat like a fucking horse when doing stuff like cleaning goat sheds.

I’m going to do this one more time, because I think it’s important to stop people getting the wrong end of the stick. Or, in some cases, the wrong stick. This information is right there, on the graphic, but I clearly should have put it in bigger letters or something, because it keeps getting missed!

Firstly: the LD50 value is for a dose taken all at once. Not over day, or several hours, but all in one go. Secondly, it’s the value at which you’d have a 50% chance of death. Some people could drink more than this and live; conversely, some could drink less than this and die. The figures are also for a person of average weight (75kg), and in reality physical and medical conditions are also factors.

For alcohol, this is the calculated value, for the alcohol content specified (40% alcohol, 45ml shots). Personal drinking history, whether or not you’re drinking on an empty stomach, and physical/medical condition can all affect this value.

There are documented cases of water poisoning (and death from it) at roughly this amount. There are also accounts of deaths from alcohol after drinking less than the amount featured here in one go.

The post that accompanies the graphic goes into lots more detail about median lethal doses, and I’d highly recommend reading it!

Is there any chance That you're bringing out a collection of these that would be available to purchase I'd love to buy one if you were

As it happens, in a way I am! If you’ve been following the site for a little while you might have noticed there haven’t been as many food posts lately. That’s because I’m currently writing/designing a book on the chemistry of food & drink, which’ll answer all sorts of questions about particular quirks of certain foods, and the chemistry behind them. I’m redesigning some of the existing food graphics on the site, and adding in a whole lot more! You can read a little more about it here.

It should be available next May (in the UK at least - I’m not sure whether the publishers, Orion, are planning on publishing it simultaneously overseas or whether there’ll be a bit of a delay). 

As far as individual posts on the site go, I do sell some of them on Redbubble. I’d love to be able to print them myself, which’d make it cheaper all round, but for now I don’t have the money (or, sadly, the time). But hopefully in the future!

Anyway, thanks for the support (that goes for everyone reading this as well), and hope you continue to enjoy the posts on the site too!

A final addition to the atmospheres of the solar system set with Saturn’s moon Titan, where, at specific locations, it rains methane once every few centuries.

I’ve also added an updated PDF download of the main graphic which adds in surface atmospheric pressures for the planets for which they are measurable. Downloadable here: http://wp.me/p4aPLT-nV

Don’t think this is accurate at all. Took 21 shots my my 21st birthday. Ten straight then 5 mins later 11 more.

I was debating the shots as well. I have taken more than 13 in one night

I feel it’s worth taking the time to clarify some points on the LD50 of these substances - the information is present in the graphic/accompanying article, but seems to be being overlooked.

Firstly: the LD50 value is for a dose taken all at once. Secondly, it’s the value at which you’d have a 50% chance of death. Some people could drink more than this and live; conversely, some could drink less than this and die. The figures are also for a person of average weight (75kg), and in reality physical and medical conditions are also factors.

It’s National Tequila Day in the US today! Check out this graphic from Reactions to learn about the chemistry of tequila - and how scientists have found a way to turn tequila into diamonds.

Would you like to know why Methanol is so bad for you? Why it gives you those “wicked hangovers”? It’s not the methanol itself but what your body turns it into. There is an enzyme in your body called alcohol dehydrogenase. It does as the name implies, dehydrates alcohols— including ethanol (“alcohol”) and methanol. So when it dehydrates methanol it turns it into formaldehyde. If you don’t know a lot of biology or toxicology, formaldehyde is a very toxic and a known human carcinogen. A third of an ounce (10 mL) will kill an adult. So really be careful how much you drink.

Most luckily though, alcohol dehydrogenase prefers ethanol to methanol by far. (Prefers ethanol to methanol by ~10-20 fold). It would much rather uptake ethanol and not bother converting the methanol (so it leaves as relatively harmless waste). This is why the antidote for methanol poisoning is actually just ethanol. (x,x

I have observed students, over 21, splash methanol on themselves in lab and simply walked to the bar, purchased a few shots and a sandwich and gotten on with their day. (Methanol does go through skin and of course drinking it would be much more serious but a drink is a medically valid precautionary method of treatment in case of spill.)

Drink too much tequila? Drink other alcoholic beverages! Lol.

One of my chemistry lecturers at uni jovially stated in a lecture, “It’s fine if you drink methanol, as long as you drink plenty more ethanol!” 

I’m guessing he realised later that the message was probably a little too casual, as he hurriedly sent an email around, the sole text of which was: “Please don’t drink methanol.”
