Copper Mine

''Copper ore is worth a lot these days. This dropper spurs out a burst of copper every 10 seconds.'' The description lies! It shoots out a burst of three copper every eight seconds! But this may be that the mine used to do it every ten seconds and the description was never changed. This shoots out 18$ worth of copper (combined) every 8 seconds. This mine takes up a 2 x 4 area.
