  • The spider crawls up the window for a minute, then slips back again for a minute, and keeps on doing this.
  • There are other acceptable variants, but they must contain the essential elements, e.g., regular ups and downs, noting its steady speed of 10 cm/min up and 5 cm/min back again.

NOTE: Do not accept "going in a zig-zag path".
