Holy crap, PASCO is a rip off!!! So for those of you who don't know, PASCO is synonymous with physics lab equipment here in the US for undergraduates. Now, I'm teaching a proper physics class this semester where we use PASCO stuff. I noticed a cool electrical generator in our storage room ( http://www.pasco.com/prodCatalog/ET/ET-8771_energy-transfer-generator and http://www.pasco.com/prodCatalog/ET/ET-8772_energy-transfer-hydro-accessory/ )that you can use to show hydroelectric power generation. I rummaged around and for the life of me, couldn't find the water reservoir, which is sold separately for some ridiculous reason. Now, we all know educational equipment is ridiculously expensive, but I had no idea it was THIS BAD. http://www.pasco.com/prodCatalog/ME/ME-8594_water-reservoir/ A plastic graduated cylinder and tube for $100. $100 I don't even know the right question to ask to try to get at the core of what my concern with this is. How? Why? Pizza? I'm genuinely afraid to try to itemize how much all the equipment in our storeroom costs out of curiosity. PS. If anyone is wondering, the "Hydro accessory" is JUST the bottom attachment with the turbine in it.
