Horizontal Relaxed, Nonsupported Drops
Description: The slinky is held by its two end coils only, and is kept at horizontal relaxed length before dropping.
Problems: There was no way to make sure that both hands held the slinky at the same height, and that the slinky was not tilted in planes other than the horizontal. Upon release, slight motion from fingers likely influenced the slinky's fall. Also, both ends of the slinky could not be released exactly at the same time. |

Observations:
In both clips, the slinky rotates very little during its drop. However, due to the slight rotation, the slinky does not land in a perfectly horizontal orientation. |
Other drop clips:
nhrn1.avi--slinky may have hit the ground on its corner. It rebounds upward, while one end remains in contact with the ground. nhrn2.avi--the slinky hits the ground and becomes flattened before bouncing horizontally and recontracting. |
