Anti-tarnishing something...
Hi. Once upon a time, saw silver utensils had a paper sheet in their box claiming the utensils would not need cleaning if such paper was kept in their proximity. Some 'magical' compound impregnated the paper My oscilloscopes are seeing little exercising of the buttons, switches, levers, controls lately... which I believe are mostly made of brass/bronze/copper. What compound could I keep inside electronic equipment that will prevent contacts to become tarnished and perform less than ideal, impregnating something ? I guess the electronic instruments would have to be covered to avoid air flow in them for such 'magic' compound to be more effective, right ?

2+ DNA tests on same individual ?
Hello. If a DNA sequence is taken from some tissue of a creature -say liver- is compared to another tissue -say kidney- of the same; are they identical ? Should they be ?

Boiling chestnuts...
Thanks. I always thought that unevenness in temperature would not be more than ~1C in the water in a boiling water pot. 99C to 100C and much has to do if covered. If cooking temperature is so critical, am done with it. And have my suspicion that in a larger amount of water boiling, temperature gradient would show greater than in a small vessel. OK. Leaving the pasta aside for another post, how to achieve the chestnuts buttery soft ?

Boiling chestnuts...
Hi. Have a good '23 Uneven results, some stay hard, some are enjoyable soft. What differs? The chestnut 'quality' itself, or soaking, or its size, or the time boiling, the depth of scaring, or else ? Read the pointy ones are edible and the rounded ends are not Some recipes call for boiling in an extra large pot with a huge amount of water compared with the volume of nuts in. I do not get what is the effect* Your expertise to obtain then very buttery soft, please ? *( as to boil pasta, why suggested in huge amounts of water and not simply submerged ? )

Religion factor
Fear + ignorance = religion = that thing zillions of people pray about daily for the last 5000 years with zero point zero results nor a single response ever and will continue like that.

Washing machine vibrations v ultrasonic transducer ?
Oh, I see. Your horizontal shaft drum instead of my vertical shaft kind of washer that the 'post agitator' fins do nothing in spin cycle. Well, in spin cycle your model does not much either. 🙂

Making fleece water-resistant
Hi. I have this product with no use for it, but mailing would be too expensive at today rates. 😡 Perhaps you can find it in UK. Perhaps a do-it-yourself here :---> https://www.ecosia.org/search?q=diy hydrophobic

Hi. Even eating such daily, in considerable amounts, which food does not contribute to build-up obesity ?- Aliens and FBI
Am sorry for the mental fart. The title I wrote shows 'FBI' and seems it is 'CIA' Do a correction if deserved.-- Aliens and FBI
Found this, anyone can create news stories with photoshop and anonymous characters. --> https://www.msn.com/en-us/entertainment/news/former-cia-agent-reveals-aliens-and-area-51-are-real/vi-AA14MsWI?ocid=mailsignout&pc=U591&cvid=c0cecc7a12bc452191354cfa2fdfc348- What would be the most important thing than humans should try to achieve in priority in your opinion ?
The main most important source of all problems that must be achieved is eliminating laziness. Brings all sorts of conflicts and problems. Anywhere there is trouble can be traced back to laziness. The relentless pursuit of comforts makes it impossible to get rid of laziness.- Where are tomatoes counted ? [nutrition]
Hi. As many say tomatoes are fruits; when having such in meals, salad, spaghetti sauce, ketchup, whatever... And nutrition suggests to have so many grams of vegetables and so many grams of fruits daily; where to count the tomatoes had ? Obviously as fruit intake ? 🙄- Do you have some movies to suggest please ?

Thank you. The same way the impregnated felt discs that work very well by 'proximity' without covering the metals ? Applying a grease/vaseline covers/shields the metal from fumes? to avoid the corrosion; fluids applied do something different more in the neutralizing the fumes action, and the felt rings work in some other way I do not know. A pertinent patent mentions lithium grease + sodium bicarbonate + magnesium oxide 🤨 as the chemicals that impregnate the felt pads. Would felt impregnated in weak household ammonia perform ?- Corrosion in battery terminals...
Thanks. Can ammonia or oven cleaner work as a more 'householdish' products ?- Corrosion in battery terminals...
Good day. Typical image from the web on automotive battery. Cleaning with wet hot baking soda is effective, the something-impregnated felt disks work well, What household product is also effective to keep the corrosion away ?- Tidal power, the steady source we seek...or Grinding Nemo?
With a couple of decades in my head on a simple turbines system that does not much to the environment; found that little people like me has no opportunity to propose/expose to the big shots how to generate energy at Gibraltar, Japan, that Canada place... Tidal currents are a proper response to clean energy.- Any real formula-1 automotive engineer around ?
Thanks. zapatos; your link does not touch the thermostat subject and seems ends pushing for a 'stop leak' product. Intoscience, please allow me a few days to respond. 🥺 - Is there a food that never makes big bellies ? [nutrition]
