Your method should take into account the physical propertiesof the substances that make up the mixture.asugar and waterbpowdered iron and powdered aluminumcwood and golddnickels and dimes
AHeat the water slowly until all the water evaporates, then scape the sugar out of the bottom of whatever you put the solution inBPut a magnet in the mixture and all the iron will stick to the magnet, leaving the aluminum behindCIt depends on what kind of wood it is, the physical form of it, and its densityIf the wood is in shavings then just pour the mixture into a pot with water in it, the gold will sink down to the bottom and the wood will float on the surfaceDIve sat here for about 5 minand this is the best one that i can think of for this one - get a window screen and cut holes in it the size of a dime, pour all the change onto there and shake lightly from side to sideAll the dimes will fall through the holes and leave the nickels on top of the screen.

Face it - your friend is incorrectThe paper side always faces the area that will be occupied - not the atticHe is wrongThe crawl space area should be insulated only on the perimeter - not between the floor joistWhy? - Most crawl space areas have ductwork/plumbing/wiring running all over the bottom of the floor joistThis makes it very difficult to install fiberglass batts in between the floor joistAnd, it provides a very nice environment for mice and other rodents to build nests inIt almost always falls down at some point and creates an even bigger messGet prices on an insulation company to spray foam insulation around the entire perimeter of the crawl space and the first joist cavity around the perimeterThe ductwork will put off radiant heat and this will keep your floors warmer and also protect your plumbing from freezing solid if you are in harsh winter climate areasRemember to close off all the crawl vents in winter monthsYou also could provide a place for termites to thrive if you install the batt insulation between your floor joist, and it makes it difficult for periodic termite inspections as the insulation prohibits any type of visual inspection of the floor system.
