Our class has an assignment on this due soon, so I can't give you a
specific answer; however, as a hint, consider rules one might apply
for finding admissible heuristics and what would happen if you did
the exact opposite.
Also, think about the definition of admissible, i.e., a heuristic
which is _guaranteed_ not to overestimate the cost of getting from a
node to the goal. What kinds of functions would violate that
I hope this helps!
