Heres a interesting puzzle that some of you may enjoy:


     A spider and a fly are both in a rectangular room with 30 foot long side
walls,12 foot wide end walls and a 12 foot high ceiling. The spider is on a 
end wall exactly 6 feet from either side wall and 1 foot down from the ceiling.
The fly is on the other end wall exactly 6 feet from either side wall and 1 
foot up from the floor. The spider can travel over floor,wall or ceiling with 
equal ease and the fly does not move irregardless of the consequences. What
is the shortest distance that the spider has to travel to catch the fly?



I'll post the answer at a later date.
