This wouldn’t produce the results you’d think it would. Ideally, the user would be the ground to produce the spark desired. But since there would be no access to the user, both terminals would need to connect to the screws to derive any load from the battery. This completes the circuit in a dead short - not resulting in a spark to the user, but heat to the pipe
Afterthought: even if you wanted to heat the pipe to mere 180 degrees, you would need a high current power supply capable of producing about 1volt at 170amps or a step down (buck) converter on your car battery to drop the volts. Passing 170 amps at 1.1 volts through a zinc-coated #12 screw will instantly cause the screws to glow red-hot, eventually reaching temperatures well over 1500°F. Still going down in flames.
What you do is go downstairs and knock on doors until you find someone who either admits to having a stripper pole (sorry but if they do this you gotta complain to the building manager) or who is so embarrassed they either close the door in your face or immediately apologize. The latter person will likely take it out without being asked
This would result in a chain reaction. A 12’ long 1/8” stainless pipe for example could reach upwards of 600 degrees in seconds depending on the battery charge and capacity. Drawing hundreds of amps causes the liquid electrolyte inside the battery to boil, rapidly releasing explosive hydrogen gas.
Interestingly, at this heat, the stripper pole would only slightly change color to a dull bronze or have a yellowish tint as red is not produced until 950F. But wood framing between floors would undergo rapid thermal degradation and begins to break down chemically. Depending on its exposure to oxygen, it will either ignite and burn spontaneously, or slowly convert into charcoal, carbonizing instantly. Of course, any laminate or vinyl flooring would melt, boil and produce toxic fumes.
The setup in this picture appears to have real wood floors, so it would just add fuel to the fire. My personal assumption? The screws wouldn’t hold up nearly long enough to produce any of the above results. The zinc plating or the screw itself would immediately boil off, showering the area in white-hot, burning metal sparks. And there would be nothing else to connect to from above. The end
