Two ways to make coffee with an Aeropress
This video shows how to make coffee with an Aeropress using a paper filter and brewing right-side-up (as described in the instruction manual). It also shows how to brew upside-down with a metal filter. The metal filter does not come with the Aeropress but we have found that we prefer it over the paper filters.

An experiment that shows yeast's ability to ferment sucrose (table sugar) but not starch. During the time lapse the foam disappears occasionally because I swirled the flasks.
how is polysorbate 80 manufactured
It’s highly toxic and dangerous.
Polysorbate use in Vaksin?
its one of the ingredients in AstraZebmnica Vaccine. Thats why im here..
Combine the fact that it's supposed to rewrite dna and rna, and if it's true that polysorbate-80 makes things cross the blood-brain barrier, i'm thinking this vaccine might rewire your brain, and make you a zombie.
and thats a bad thing?
@@SomeRandomPiggo All i know is, the head of the deep state is a company run by a family that has it's office in Stockholm, and this company is also the parent company to this AZ drug company. So, probably a bad thing, yes.
Аnd in Russian Sputnik V too... This is why I am also here...
@@rBennich how do you reverse it
Could you tell me what is the plante that the tween 20 extracred from ??
Sir can you please biodiesel all testing videos .
very nice thanks
is there a way to isolate Thorium 232 isotope into a gas? Or is Thoron gas the same thing? I know there are 5-6 steps of Thorium decay before reaching Rn-220, but I was wondering if a Thoriim 232 Isotope can be stabilized as a 90Th232 gas. Thanks
Extraordinnary explanation

Do you really have THF going through a rubber hose there, or am I seeing it wrong? Could this not ruin your distillation since THF will dissolve some of that rubber tubing ?
so is it subconsciously clean and pure cause cream is white?
thank you once more
thank you so much . I d like to make polysorbat 80 myself. Is it possible?
I have it in a vitamin tablets, and tablet makes me really crazy and also other people became strange. I wonder if its just poly80 who makes that ?
Hi Joe, whats the longest time you would store a new un opened THF bottle for? And after how long would you not dare open it, if its been stored away from light and has been stabilised with BHT?
dude read how to test it for peroxides.. you can see the solids build up over time
Κ not like the real proceso, you make soap when you shake this way.
The triglycerides have already been turned into biodiesel and glycerol, which make up the two layers that you see at the beginning. This video is about purification of the biodiesel: removing the glycerol and other impurities using liquid-liquid extraction.
