    the rubber dam was put on upside down, the taper goes toward the funnel.

    This is awesome, thank you.

    Go to a hookah bar and you'll see that this trick has been out there for a very long time my friend

    Heat up the end of the hose in hot water to make it easier to push over the  hosebarb.

    Would this work if you dissolved sugar in water?

    ….the gasket didn't "just come with the kit". With out the funnel gasket, you would not be able to generate a vacuum. So the filtration process would still take forever, sans gasket with vac pump. You made the video, I have no formal education past the 3rd grade. Do you think what I'm saying is technically accurate? if so, then maybe you should edit/remake the video to highlight the importance of the funnel to beaker gasket. yes?

    Another good thing to use for filtering on top of a flask is a ring filter.

    Highly appreciated pimpen but I got to your vids by looking up the brand Florex which I imagine is the brand u use..! In any case I'm seeing what you think about ten holding up to the heat?!! Thanks

    That's what he said: "we don't like loose things, of course"

    Ya…and if you don't want to use your hands to do the work to make the vacuum you can have a wash to do the work for you, and this will make big filtrations much easier to not mess up… because if the liquid e.g is overflowing it will end up in the sink. Sorry for bad English. ;D

    No, we don't like loose things…

    Jesus my English went too hell. I was just saying, rotate the funnel until the longest part of it (the point side) is facing toward the arm, to help prevent your filtrate from being sucked into the hose.

    The only thing I saw different in your video Bucky from an industry lab is. (Well the lab I work at). We often times turns the funnel so that the pointy is backed toward the vacuum side arm. Using an industrial vacuum pump vs your handheld one, has so much pressure that it can pull your water into the arm/hose. Hopefully that made sense. You can also puncture a hole in a rubber stopper, add vacuum grease (lube really). and insert funnel into it so that you don't have to get a "special" one.

    Hey Bucky, could you do an experiment making coffee using a chemistry set like on Breaking Bad?
