Have you noticed a very fine particulate getting suspended in the solution from the celite? I can only see it with the right intensity flash light or maybe a laser. This suspension never seems to bottom out and ever since using this through a fritted filter, I get this suspension in any solution that goes through the filter now. I can also see some of the silicon dioxide around the edge of the frit and it does not want to budge from normal cleaning. I'm trying to figure out the best way to clean it properly but I haven't had any luck yet. I'm thinking I may need a dilute solution of sodium hydroxide at just the right concentration to dissolve and potentially loosen the the SiO2 without damaging the frit.
The internet is a human right because it's a great education equalizer. Before the internet the kids at the best schools had the best teachers but now even a kid with access to the internet in Nome Alaska can have access to the same great professor as rich kids at Harvard. The internet is a challenge to the traditional education paradigm which required every school to have a professor teaching the same 101 course and now any autodidact can access Penguin and learn science.
these are so fun to watch AND they're entertaining i feel like it's so hard to explain a concept that you already know so well as something that is easily digestible for newbies and this does it super well cause it actually makes sense :O (and again youre super funny)
