The guy in the pink tie, sat with Alan Davies, is John Lloyd, who is the creator of the show. I think he was only a panellist because someone else cancelled at the last minute
1) Fill a bucket it with water to the brim and weigh it. 2) Completely immerse your head in the bucket, which forces some water out of the bucket. 3) TAKE YOUR HEAD OUT OF THE BUCKET! 🤣 4) Weigh the bucket of water again - the difference in weight between the full bucket and the less full bucket is the approximate weight of your head.
qestion could have been: 'How could you test the density of your own head? without a Scanner'. The prime answer relied on knowing that info. If heads were as dense as mercury, you might need a gram of mercury......
The red light and alarm has multiple triggers. It's originally for someone saying the answer that most think of as the truth (but isn't) and it also serves as a way for the production to predict what wrong answers the guests will say, or humorous comments they will make.
@@AdeboFunkyVoodooironically, its because we get so little sunny days that people completely underestimate sun exposure on clear and slightly cloudy days thinking that you can only get sunburnt on really sunny and hot days
Sir Walter Rayleigh died in October 1618 by beheading. His head was embalmed and at some point after that was given to his grieving wife… I bet THAT cheered her up! Anyhow, that’s how she became the custodian of her husbands head which she carried about in a velvet bag for the next 29 years. Presumably it didn’t whiff too much as it had been embalmed. As a side note:- His body was originally interred in a church in Beddington, Surrey, but later moved to St Margaret’s Westminster where it lies today. After his wife’s death the Head was also interred at St Margaret’s Westminster too.
Water displacement - read up on Archimedes on bath night. - The programme is "Quite Interesting" they are expecting interesting answers from the guests. If you give an answer that is obvious, or a common phallacy, wrong, or your name is Alan Davies, then the claxon is likely to go off, and you will lose points. The person sat next to Alan Davies answering questions on this episode is actually John Lloyd, the producer who came up with this game in the first instance and was responsible for bringing Davies and Fry together 21 years ago
We learned in school the theory of displacement by using a can with a funnel drain off then you fill it with water up until it drains off at the funnel then you put a small weight in until it drains off the liquid equivalent of the weight. I think it was called a ureka can or vessel, This gave you volume of the weight displaced.
I like to wear hats a warm wooly one in winter and a cap on summer .The 'elves ' who set the questions think of the most predictable answers and the klaxon sounds when a panellists comes up with it - minus five points .Alan is always on the panel and occasionally takes a hit when the others are stumped or stalling which is why the scores at the end are mainly negative and he often comes last
The head-weighing technique is really very straightforward. First make a hole in the water with your head, then fill the hole with plaster. When the plaster has set, use it to create a replica head out of - say - lead or gold, then weigh the replica. Simple! My own weighs about 93lbs. 😊
The Klaxon you have heard sound twice and the words flashing up on the screen are a result of what a panelist has said. In the first series Stephan used to have a stack of printed cards, that he would show, which evolved into this. The words/phrase come up on the screens and the sound made when a predicted answer is given. For example, should Stephan or Sandi ask Whos is the most hated person in all time? and a pannelist to be humourous answers, Piers Morgan, or The Prime Minister or such like, If the Qi Elves ( which is what they call the folk who research and set the questions ), have predicted that someone will give that answer, then the alarm goes off and the phrase flashes up on screen.
I’ve always watch QI it seems much easier to learn these facts when they’re mixed with comedy They stick in your memory then. The buzzer is there for when you get the wrong answer you then lose points.
Kia ora from New Zealand! I've wondered what you looked like without a hat, very nice!! Have you watched any of Joe Lycett, John Bishop, Greg Davies or Sean Locke's stand up etc?
Displacement: Weigh the water in the bucket [ eg. 20 pounds ] Stick your head in = Some water is forced out / displaced by your head. Weigh the water in the bucket again. The difference will give the weight of your head ! Archimedes - ''Eureka !!!'' - after seeing the water in his bath displaced by the weight of his body.
Put the bucket on the scales, fill it with water to the brim and weigh it. Put your head in up to your neck, displacing the same amount of water by volume as your head. Weigh the leftover water and subtract it from the original reading to get your answer. If you use a bucket with a calibrated scale you can do it without the scales as each millilitre of water weighs one gramme, so every litre weighs a kilogramme. Just calculate the displaced volume of water and convert to kilogrammes for the answer. 👍
For the klaxon, It’s minus 10 points to anyone who suggests an obvious or conventional answer which the show goes on to prove is not true (or at least not fully true). Every contestant gets a a score at the end of the show and usually most of them have negative points. Sometimes the winner will have like minus 15 points
My guess prior to watching: Measure an empty tub of water. Immerse yourself in it up to your neck and measure it. Then fully immerse with your head then measure again. Then your head's weight can be worked out via water displacement.
The siren goes off if an obvious answer is said and then you loose points. If you were to do full episodes you'd see Alan usually ending with -50 points or less. As for the bucket, you fill it to the brim, weigh it, stick your head in it, without hat, and then the water comes out due to displacement and then you weigh the bucket again, subtract the second weight from the original and there's the weight of your head. Also John Lloyd the smart guy on the panel is the creator of the show.
A few years ago (1984) I had a hip replacement and kept the ball from the femur. After a few days it started to stink so placed it in the oven and roasted it for a while, problem solved. The smell was delicious.
She could have baked/cooked the head, before carrying it around as a handy snack source, getting lighter by the bite!! The show is intelligently great. Archimedes principle does apply to weighing heads or any other body bits you may wish to weigh😂😂
The klaxon is fro obvious wrong answers that some people think is true.David Mitchell argues about the naming of world war 1is a good example of this, short clip but hilarious.
Water has weight. Pit your head in a bucket with a bowl underneath to catch the water. Weigh this displaced water. The water weight will equal your head weight. As the meerkat says - simples.
Qi is awesome, it's like a continuation of school. The alarm goes off when a player has stumbled into an 'answer trap' ie, the production team knew someone what come up with that wrong or not entirely true answer. Great reaction guys. 👍🏻
She carried the head as she never got over his death, it’s like people who stuff their pets! In Victorian times it was quite common to photograph dead bodies as if they were still alive and have the picture on your mantle! As seen in the horror the others!
The idea is that you weigh the amount of water it takes to fill the bucket. Then, when you put your head in an amount of water overflows out of the bucket. Then you weigh the amount of water remaining. The difference between the starting weight and the remaining weight is the weight of your head. I think.
Yes i agree except that in order to be true it would have to be of equal density. Eg a lump of metal and a cricket ball the same size would weigh the same by this theory, which is not true
Pfft, I'm from the UK, and realistically, the only time I'm not wearing a hat is when I'm in the office... Loads of folks wear hats here; whether it's a beanie, a snapback, a flat cap, a cowboy hat - we all have our poison of choice!
No Nick, you weigh the full bucket of water first then stick your head in slowly which displaces some of water and weigh the bucket again with the water that's left, so then you know the weight of the water that was displaced
Given that in the 17th Century, we still crapped out of the window into the street below, a severed head was probably the least stinky thing you'd encounter on a day to day basis.
Put a bucket of water in a empty bowl which you previously weighed. Stick your head in bucket, the bowl catches the displaced water, remove head from bucket then the bucket from the bowl. Now weigh the bowl with the displaced water in ,subtract first weight now you have your head weight. Sirens are for obvious but wrong answer. 😃
Depending how much water is displaced you can work out the weight. If it displaced for example 2 litres of water that would mean your head weighs 2 kilos. 1 litre of water weighs exactly 1 kilogramme.
9:30 - I wonder if this is part of the reason why men have dominated the sciences for so long: their willingness to do silly experiments ("blue skies research") that have no obvious applications at the time, but later turn out to be useful. It is one of the realms where an almost "childish" sense of curiosity serves you well.
The red light and siren goes off when an old generally debunked answer is given ,such as an old myth that many people regard as being true but has been superseded by better understanding and advances in science and discovery.
10:29 using water for weight is very simple. it's called the Metric System (1 cubic meter = 1 liter of water = 1 kilogram) although in this case it works because the human head has a similar density to water. i hate to think how complicated it would be to calculate in the US
If the head displaces 5 litres of water and 5 litres of water is 5kg and we know the head is approximately the same weight as water. We can deduce the the head weighs approximately 5kg.
surely you can just lie down on the floor and rest your head on scales? I so wish i had a bathroom scale so i could now try this but i don't. the siren goes off when someone comes up with a cliched or predictable wrong answer - I am now wondering whether that would have happened with my suggestion. I have often thought that this show is like chatting with my mates down the pub after a couple of pints.
Please dont stick your head in a bucket of water on your own...obviously.. But do place a 2nd bowl to catcg the displaced water from the 1st bowl, then weight the 2nd bowl of water or convert the fluid ounces into weight of your choice.
The shows researchers(aka the QI elves) set the questions and predict the obvious(but not necessarily wrong) answers(or jokes) the panelists might give, they also operate the klaxon which goes off when a panelist falls into one of their traps and they do the scores(the rules and scoring system have never been fully explained as far as I know as it's quite arbitrary and mostly irrelevant), all we really know is that panelists lose 10pts if they set the klaxon off and that Alan doesn't win very often, particularly in the early series when he almost never won(which they kinda played up for comedic effect).
the klaxon is set off when someone gives an obvious or cliche answer but it's actually wrong. if you set off the klaxon you lose a point and if you watch a full episode you'll see it is not uncommon for people to end with a negative score.
Sandy is a feminist lesbian. She's become more vocal about it on the show as she progresses. It's not really a problem, but sometimes the I'm a lesbian comments get a bit boring and repetitive. Generally though quite funny, but very dependent on the panelists...
If it was not popular you wouldn't be watching it on RU-vid it started in 2003 I don't think a telly show would be running that long if it was not popular?
You look better without a hat! Never understood the American thing about wearing a baseball cap not only when not actually playing baseball, but when indoors when you don’t need protection from sun or rain! Worse than that, wearing it backwards - why? To keep the rain and sun off your neck? Most Europeans think it’s completely daft.
You are teachers yes? Weigh a bucket of water, place your head in said bucket of water & don’t drink it. Hold one’s breath for a few seconds & once all the water leaving the said bucket leaves, then take out one’s head & weigh said bucket again. The difference between the full bucket & less full bucket will approximate the weight of your head. Get me! 🇬🇧😎🤣
Sandy Toksvig was always pretty good as a guest. I think she usually won. But on a serious note: with "who really cares" we would likely still live in caves. Imagine how people laughed at the person who had just invented the wheel... You'll never know.
I'm not sure that you could easily weigh your head using Archimedes' Principle with a American heads. Americans tend to be pretty dense as this video proves.
