On umbrellas, springs, and superconductivity

Well after a few months of a hectic summer, rains are here. The campus is green and nature is once again abundant. With rains, however, has also come a usual game of hide and seek. Every time I take my umbrella out, the rain is nowhere to be seen. But when I forget it, I am greeted by sudden bouts of rain spoiling my ambition to reach my class dry and tidy.

Umbrellas, however, have something amazing about them. You press a button and it automatically opens up, stretches itself, and unfolds into a shade, growing much larger than it was. Like a magical genie.
