The idea of the ink fountain is to follow the idea of the current thermometer, fill the sealed conduit with mercury, and delineate the ambient temperature according to its expansion.

The conduit has no choice, and the ink fountain doesn't believe that he can make a metal conduit with a completely uniform inner diameter with his casting level, but the bee kiss is the boss material, not to mention the rest, the uniformity is certain, at least the middle part is the uniformity.

And the length is more than 20 centimeters, which is just used as a thermometer.

The medium, of course, is mercury, the thermometer wants to be accurate, look at the expansion coefficient, it can't be too low, like water, boiled and only expanded a little bit, then the catheter is required to be extremely thin, and the bee kiss obviously can't do it.

But it can't be too high, such as alcohol, which expands violently when heated, firstly, the risk is very high - who knows if it will break through, secondly, the fluctuation of the degree will be very significant, thirdly, the alcohol is very volatile, and it is impossible to do a vacuum in the game, and the quality of the alcohol in the bee kiss itself is not fixed, where can it be accurate?

Mercury is the only liquid metal at room temperature, the coefficient of expansion is much higher than that of water, but it is also significantly lower than that of alcohol, which is moderate, and because it is a metal, it expands evenly, and the volatile interference is relatively smaller.

With the catheter, how does the mercury come from?

To ask what is the greatest effect of ancient mercury, alchemy.

Most alchemists will eventually die from the elixir they have refined, the most famous is Emperor Jiajing, and the cause of death is very simple, salmangic poisoning.

There are so many alchemy recipes handed down in ancient times, but there is no one that does not have mercury added to them.

In ancient times, everyone found a kind of "water", which has a metallic luster, does not dissolve in any liquid they know, gathers with each other and will not be scattered, and can also be used for embalming, such a magical thing, what would the ancients think he was?

But this thing is extremely dangerous and poisonous, let alone directly ingested, even if the thermometer is broken, it is not a trivial matter.

If you want to do it, it's actually simple, the main ingredient of cinnabar is mercury sulfide, which is non-toxic - otherwise ancient women would not use this as lipstick.

It is non-toxic, but after heating, sulfur ions are oxidized into sulfur dioxide, and mercury ions are reduced into mercury element, which is directly condensed and collected.

Anyway, the ink fountain is also according to the ancient method, find a sand glass and put cinnabar in it, and set up a shelf below to put firewood to burn, and then tilt a little outside the whole to buckle a cylinder, put a basin of cold water on it, and the mercury vapor condenses and gathers on the cylinder surface, and drips down to the container along the cylinder wall^

Forget it, just let it drip into the bee kiss, and pour it again when you are too lazy.

First open the furnace and burn out 2 spherical sacs, 1 hollow one for mercury, and 1 solid one for sealing when the time comes.

Don't make it too big, the mercury expansion coefficient is 1.82*10^-4, that is, it expands 1.82% per 100 degrees, take this as the standard, almost calculate the length and inner diameter of the bee's kiss, anyway, when it burns to 100 degrees, let it account for about 90% of the catheter.

Others are easy to measure,The inner diameter is not difficult,The game has a magnifying glass,Change to an external monitor,Integer magnification,Take a vernier caliper and stick to the screen ratio,Measure several more proportions,Roughly accurate or can be done。

After doing it, put it under the wall of the tank, go directly to the second floor to find an empty room to start the fever, and the doors and windows are closed!

Half of the amount can be put in the bee kiss, flattened, let the mercury leave a little into the bee kiss, and then the bee kiss is placed diagonally, take something to block the mouth at the bottom so that it does not leak out, and when it is filled with a bag, insert the bee kiss upside down at a slightly faster speed, everything is fine, and it is good to fail a few more times.

This ink fountain didn't dare to use six dings, but took the system candlestick to lead.

The ordinary fire was obviously not as violent, and after burning for a few minutes, the mercury began to drip down little by little.

Before that, the ink fountain had been poisoned.

Injuries are trivial.

The key is health.

It was always -1, and after a while he was already "terminally ill".

Attack power, skill rate/success rate, toughness, and all aspects are greatly reduced, and one other bad status is automatically deducted every second.

Disgusting to death.

Bear with it.

After burning for a long time, by the time the backyard drainage was done, the health of the ink fountain had dropped to less than 10 points.

But this side is already filled with a pouch, and there is about one-third of the tube in it.

And the system also gave 100 points of alchemy experience - of course, he actually wanted alchemy more, after all, the skill of alchemy could not produce anything without a formula, and this kind of scattered experience was given in vain.

Remove the capsular bag and quickly intubate!

The density of mercury is 13.6, but the tension is only 6 times that of water, and the speed of dripping is of course faster than that of water, even if the ink fountain has been prepared for a long time, or some of it is dripping.

Hurry up and cover it with sulfur powder, the window is closed, but what if someone else who goes out is poisoned, and the system counts him as a red name?

The bee kiss is not sealed for the time being, go back to the kitchen downstairs, boil the water, and put the bag directly inside.

The mercury column kept going up and stopped when it reached 80%.

It feels like it's okay.

After all, the inner diameter of the bee snout is small, and if you use other things as a catheter, you can't see the change at all.

Yes, seal it, and at the same time take the dagger and engrave it in the scale slot, this is 100 degrees.

And then it's 0 degrees.

Looking for cold water, the cold of the day is crazy to smash in.

It's useless, it can be cooled, but it can't be frozen.

It's okay.

I caught so many fish just now, and now it comes in handy.

Take off all the equipment with mana, it's 256 mana.

Moved a fish tank into the house, caught the two or three fish of 30+, and sent the cold of the day over, 197 points, looking at the blood volume of the fish, it seems that it can only be carried a dozen times.

Then it's okay to add blood to it while fighting.,Rights and interests 4 seconds to read the bar.,But Tianya has a skill that is uninhibited.,The effect is to add a fast-casting version to the active skill.,He only clicked one level - pure cave seclusion micro passing.,Of course, the effect is scum.,But at least it can be used.。

The full reading bar of the equity 4s is 659 healing amount, and the 1st level tuoluo 1s reading bar can only be added to 98 points, and the damage covering the cold of the day is almost okay.

Crazy hits, crazy.

After 21 times, the frozen three feet were lit up.

Released directly, the skill freezes both the fish and the water next to the fish.

After freezing, quickly put the fish into the food box in the backpack, don't really freeze to death.

After freezing 1 and freezing 1, and then putting the first one back to continue freezing, not long after, a lot of ice has accumulated in the tank.

Let it sit for a while, wait for the heat to be conducted for a while, and the ice cubes start to dissolve a little bit, which is the standard 0 degrees for the ice-water mixture in that scenario.

After two or three minutes, depending on the situation, it should be okay, and the thermometer is inserted directly.

An unforeseen circumstance occurred when the mercury retracted into the capsule.

But fortunately, it didn't shrink too much, and a little tilt will still come up.

That's easy, switch to the display mode again, and tilt the bee kiss slightly so that the liquid level just reaches the contact surface between the bee kiss and the capsule.

I tried several times in different positions, but it was still to prevent the temperature of the water from being different at different locations.

Determine the angle α, copy the ruler to the paper, make a right triangle, and measure its tangent.

A very simple calculus calculates that the volume of the upper part of the sphere without mercury is 1\/3πR^3(1-sinα)*[2-sinα-(sin^2)α] in the case of inclination α;

To find this part of the volume, the unit volume of the bee kiss is known, and it is naturally easy to calculate how much the liquid level height is negative in the vertical case, that is 0 degrees, the distance to 100 degrees, 100 equal parts in the middle, and each minute is 1 degree.

Of course, it can't be a one-time 100 copies of all points, 5 5 to come, 20 degrees and then 5 equal parts to get 4 degrees, 4 degrees down direct visual inspection on the line, anyway, you really need to be accurate to try the 20-45 range, other places are a little larger error is completely acceptable.

After carving, I got a recipe, a thermometer, a technology, and the experience is of course 100, where did the thermometer come from in ancient times?

After doing this, the hatching eggs are ready to be caught.
