Why The Bottom Of A Slinky Appears To Float In Midair When Dropped

This is a video of The Action Lab’s James Orgill getting all sciencey on us and explaining why a dropped Slinky’s bottom portion appears to float in midair until the top catches up with it, at which point it starts falling. SPOILER SPOILER SPOILER: Magic. It’s as simple as that. Or, I don’t know, something about it not being able to fall until the tension in the line decreases, and that only happening when the pressure wave traveling through the Slinky (which travels at a finite speed) catches up with it. “I liked magic better.” Just like the good old days. You know I see ghosts if I get up at night and don’t wear my glasses.

Keep going for the video with a supercool look of a Slinky with a roll of duct tape attached at the bottom appearing to float at 1:45.
