Actually, you can drink mercury without causing much harm as it doesn't get absorbed fast enough through the intestine before it goes out the other side (high specific weight :-) ). The issue starts when you inhale the vapors. Especially in concentrations as I would expect are present in the video above. It gets to your brain and never leaves it. If you are eager to destroy probably the most complex object known to men go ahead and breath it in. I rather don't. Doesn't affect just you as there are most probably people that care about you that will suffer with you

I'm very glad you made this pump. It's one of the classical masterpieces of scientific laboratory inventions that's similar to a typical water aspirator but relies on the high density of mercury. One thing I have to warn you about (and I keep warning in in every video where you work with glass) - anneal your glass! Download a book on flameworking and see the details; they can make a difference between successful apparatus and an explosion/implosion. The joints you've made are extremely unstable and prone to cracking. I was very surprised this thing actually survived. You're working with glass as if it's metal. It can't be suddenly attacked by vicious sharp hot flame and then quickly left alone without storing enormous stresses inside and I'm positively certain that one day such practice will make you pay. Please be more careful. BTW, the charge separation is very common in vacuum systems. This one is similar to Kelvin water dropper. One initial difference will build up. Also, Sprengel is pronounced ['ʃprɛ. ŋəl ] as it's a German surname. G is hard and S is sh.

That could create a slug of mercury in the line, preventing a good evacuation of the radiometer bulb. To get rid of that mercury, leaving the lamp on it, to heat the mercury in the radiometer hotter than the mercury in the Sprengel pump would eventually evaporate the mercury, and it would condense in the pump. He really DID do it the right way, though he could have solved the problem by putting a trap in it, so mercury couldn't back feed into the radiometer. Live and learn, that's why this is called an "experiment".

I know this is a few years later, but I'd say "no". Reason is because the bubble of air is less dense than the mercury pushing it down and if the tube has too large of a diameter, that bubble of air would overcome the surface tension of the mercury and escape through the slug of mercury above it. However, there's nothing that prevents you from having multiple Sprengel Pumps attached to the same chamber running in parallel to pull the vacuum faster.
@lollibone5 жыл бұрын
I'm even later and I think John is right. You can probably increase the diameter slightly but I doubt by much. There are however other adjustments that can be made to better the efficiency, like Cody said, the kink he had in his tube was an issue.

A fork somewhere possibly could work? so that it runs from one mercury supply, has one vaccum-creating inlet, and finally one spout, but in between there would be 2, 5, 100(???) capilaries? I wonder what, if any, the limit is. With some kind of powered mercury pump (I'm thinking low-power, slow-geared Archimedean screw), this possibly could be made into a pretty fast, super-efficient and extremely potent portable device? I would love for someone to tell me whether this could work!
@mpirron15 жыл бұрын
Yes absolutely, Sprengel's device worked in less than a half hour on a half liter of volume. it just depends on how intricate you wish to get with your glasswork.. For instance you could go as far as making multiple stages to pull down the vacuum as the Mercury falls, collect a bit of it and let it continue thru another trap before catching it. Sprengel himself did not actually create the device, he connected to the intake of a water powewered pumping device called a trompe, the precursor to an aspirator pump that had been around since the 16th century. The trompe had several stages so it's likely my guess Sprengel's apparatus did to when he filled it with Mercury instead of water.

Edison's laboratory in Greenfield Village in Dearborn Michigan has a mercury vacuum pump used to evacuate early light bulbs. It is made of glassware, but I've never examined it closely. It is about 15-20 feet from where you can normally get to. Next time I go I'll have to look at it more closely, or ask questions of the docent.
@BenFogt5 жыл бұрын
Thanks for sharing. I spend 2 days a week in the Menlo Park Lab at Greenfield Village. We have several Sprengel pumps as well as a version Edison used later to make his bulbs faster. You should visit. Maybe contact the curators for measurements or a special visit. Anyway, now I can explain how they functioned. Our narrative says that the Sprengel pump took up to 7 hours, but the newer versions took only 25 minutes to achieve complete vacuum.
@BenFogt5 жыл бұрын
I'm going to add a little to this. If you read through Edison's improved pump patents, of which there are many, he writes that the optimal temperature for the mercury is 100°-105°F. That's definitely not the safest thing to be heating, but you had some room temperature-wise. I've also learned that Francis Jehl taught lightbulb making at the Edison Institute in it's early days. The institutional memory indicates that the last step in the process was to burn the filament a bit, evacuate the smoke, and repeat until it doesn't smoke. So even these pumps weren't perfect.

That's why you should try to avoid saying "I made it absolute zero" because you theoretically can't create nothing.

That defeats the point of my first argument about it being impossible to create nothing if I said you can create the absence of something.

Cody thx for sharing the concept, the build and the results. Very cool old tech that was used for practical purposes. After looking at the pump for a while it dawned on me that this is an HAC (hydraulic air compressor). You are taking the vacuum vessels air and compressing it to atmospheric pressure. Moving a gas from a lower pressure to a higher pressure is the definition of a compressor. HACs also don't have any moving parts, are quite efficient and usually powered by falling water. In your case it's falling mercury. Again, thx for sharing.

If he did that, it would not light continuously, but rather, it would flash repeatedly. It takes a lot of voltage for a fluorescent tube to strike, but the holding voltage is much lower. Since this doesn't generate any appreciable current, it will drop out, until the voltage builds back up enough to strike again. Something like a relaxation oscillator. Don't get me wrong, it WOULD be interesting!

Here are three potential enhancements in case anyone is inspired by Cody's video to make one. 1) A syringe barrel and plunger, two homemade one way check valves, and some tubing to make a piston pump that will help eliminate handling/spilling the mercury. Use a syringe with a thin barrel and plunger and make slow strokes so as to not push mercury past their gasket materials. 2) The mercury reservoirs at the top and bottom may be enclosed containers with a tube connecting them at the top of each reservoir container so as to contain but allow displaced air and mercury vapors to move between the two. The tube can have a release valve to vent buildup of evacuated gasses and filter the vented gasses though a sulfur-impregnated activated charcoal filter. 3) Include an electrostatic discharge wire between top and bottom reservoirs. Now it will be much safer.

I'd guess the voltage would be a factor of run time, humidity and a few other random variables like conductive paths caused by contamination. Blinding accuracy wouldn't be a big issue, so I'll make a modest proposal that doesn't involve broiled children. 2 high voltage 500 meg resistors ( one for each probe leg ) with the 10 meg meter acting as the third resistor in a voltage divider ( 100:1 ratio ) so with a fluke the full range would be apx. 250000 volts. Couple of acrylic tubes to be the probes with resistors mounted inside. Could put a trim pot and resistor across the meter to extend that range if needed, and allow calibration.
