Here's a puzzle for you to solve:I need to build a machine that can differentiate between copper, zinc, iron, magnesium, and aluminumObviously I could isolate each metal slowly and by hand, but such a method is ineffective in my situationI have the mechanical and programming know-how to build such a machine, but how does one actually differentiate between the two? For example, what different characteristics of zinc and iron or copper could the machine identify in order to differentiate?Many thanks.P.S.: Please answer only if you actually know the subjectBeing in an earth sciences class does not make you an expert on the matter.
Copper is the only one with a yellow color Iron you can pick off by a magnet What are the pieces? random shapes and sizes? Varying amounts of corrosion and dirt? Because it can be very difficult if not impossible to automate on a one by one basis the remaining metals IF they are a uniform size and shape, like coins, you can separate them by weight, ie, density And what about alloys, various steels, brass, bronze, various aluminum/magnesium alloysSome stainless steels are not magneticA penny is 98% zinc but appears to be copper in appearance because of a coating of copper on the outside.

This way is a little different from some g-bongs but will get you the most stoned man! Get a two liter bottle, clean it out, and cut a hole in towards the bottom on the side of itthe hole should only be about the width of a penThen make a bowl out of aluminum foil that fits where the cap goes on the bottlePoke about five holes in the bottom of your foil bowl with a toothpick or somethingFill up your bowl with your grass and set it asidecover the homemade hole with your thumb and fill the two liter completely with water from the tapThen lift it up, keep the hole covered, and put the bowl on the top where the cap goesLight it up with your lighter and let the hole go with your thumbThe water will pull THICK smoke down into the bottle :) when it's burnt out take off the bowl and suck in the smokeCOUGH like hell and feel the instant high manhave fun!
Wich would be the cost, for a handmade bicycle builder, of a high end steel tubeset like Reynolds 853 and what are the size options for the headtube (i.e1 1/8, 1.5, tapered.)?
Yep, cranes lift a lot-steel, concrete buckets, even workers (rarely)Cranes are begun with small lifts near the ground, and assembled in piecesThe highest ones climb up the beams floor by floor as the skyscraper risesWhen the top is built, the crane is taken apart and pieces lowered by a very small craneThen that one is taken apart and comes down an elevator.

I've done all the other things I'm supposed toI wrapped my trailer in foil with 7 layers of duct tape and threw 39 tires on topBut I still feel that they are penetrating my inner-thoughts.
I'm glad that you remembered the exact amount of tires to put on the top, 39Any more, or any less would prove disastrous results However, it's also vitally important that you have the tires perfectly aligned and have just the right amount of tread depthThis keeps the aliens mind control recessed and unable to penetrate The deeper the groves the more thought waves will bounce off and bombard against the protective aluminum foil( make sure it's the shiny side up) Last but certainly not by the least , it is of utmost importance to rotate your tires into the symbolic 9 Enneagram This requires you to stack the tires in 13 piles of 3x3x3
Aluminum siding on the house's exterior was installed in 1981. It's now fading somewhat but it still has held up well.Rather than completing renovating the exterior with new siding or a facade, I'm thinking of power/pressure washing the siding and then painting it.Can aluminum siding be painted and is there a special type of paint to use?Thanks.
pressure washing is a great idea but don't stand too close i would let it dry and primer it first some the paint would last longer...stay on surface relax vote for a best answer.
I have to make some sort of launching machine that can fling a small rubber stopper with these materials:5 Paper Clips2 Pipe Cleaners30 cm of aluminum foil1 meter of string2 straws2 coffee stirrers (the tiny straws)There will also be a hammer available as dead weight, you can't give it any potential energy at allThe most you can do with the object is pull something back and let goYou can't thrown anything (obviously), nor will you be able to hold anything down yourself (that's what the hammer is there for).I'm very curious to see your ideas! :D
I would form the paper clips and the pipe cleaners into extension springs and then rig some kid of way to attach the stopper to the springs so you can pull them back and let go.
