The thing you may be missing is that without the argon, aluminum welds extremely poorly, molten aluminum combines with the oxygen in the air into aluminum oxide which basically won't stick. Google image search 'bad aluminum welds' and then 'aluminum weld without gas'. The worst ones with craters that look terrible are when the gas was low or not working.The argon is blown at the weld point while the weld is being done, so the oxygen can't touch it while the aluminum is molten and become aluminum oxide and get deep into the weld. Once you're done welding, the surface still oxidizes later like normal but that's just surface oxidation, the weld is internally still strong.
You could always take the basic idea and convert it to non-suction cup. If there isn't already a blinds or other place to connect to at the top, put a small screw or nail either in the center for both or one on each side, and put the strings up to that. Have some extra length and several loops and you can easily make it fit different windows. Then mechanically attach the other side to the sill or sides of the window frame area. You could even just use 2 more strings slightly shorter, and suspend the entire thing, but it would be easy to move away from the window. Keeping two suction cups there to keep it fixed should keep it from moving around, while not really depending on them 100% for support by having the inside edge strings to take the weight if they let go..

Actually it's about as misleading as anything else. Because of height, it's really only a good representation of the high density population centers. NYC with it's overwhelming height displaces in ways it shouldn't, the areal flat spread population isn't represented well in this map in comparison. Some of those 'near empty' looking states have significant population, it's just spread out and doesn't make much in the way of peaks. The shift between area and height for population with this map would make almost everyone have a lot of errors trying to read it accurately.. NY is roughly 19 million, NC is roughly 10 million, so more than half of NY. But almost no one would judge that correctly with NYC towering over in NY..
Not knocking it for what it is and looks cool, just recognize it has it's own limitations for trying to present the real population spread accurately..
Only the volatile parts of WD-40 evaporate. While that's a lot of it, it specifically leaves a residue or it wouldn't work to quiet metal on metal hinges once it evaporated. From one of the discussion groups way back, one of the components is rosin, part of why it attracts dust and dirt after it's been used on something. Great for what it's good for, terrible for contact with things that will need further finishing, like everyone is saying.
What place is that? Regardless of how great your place and neighbors are, less nice people target neighborhoods by pretending to solicit for other things, and trying the door handle and looking for close keys if they don't get an answer, hear dogs, etc. Your door should normally be locked even when you're at home even in a nice neighborhood, not doing so is like not wearing a seat belt. The correct habit is just as trivial and easy as an incorrect one, it's always the better move to develop the correct habit and let it become the automatic one from a statistics standpoint..
