Terms & Conditions
This room has no doors, no windows and no other hole large enough for the prisoner to escape via. He has no tools, he has no assistance. He does have a table and a chair in the centre of the room. The room is quite large, walls are two foot thick.
How can the prisoner escape?
Hint: This is a trick that you'll never guess, but is something you'll remember for a very long time.
First he rubs his finger on the table until it is sore, cuts the table in half with the saw. Puts the two halves of the table together to make it whole. Climbs in the hole and shouts until he is hoarse. Climbs on the horse and rides away.
Can you draw the following without lifting your pen from the paper, or going over the same line twice, or crossing any line?
Answer: It cannot be done!
For his breakfast, Mr Stone likes an egg that has been boiled for exactly 9 minutes. He has two egg timers (those with sand in them), one that runs for 4 minutes and one that runs for 7 minutes. How can he use these timers to boil his egg?
Hint: Start both egg timers.
Answer: Start both egg timers. When the 4 minute timer runs out, turn it over. When the 7 minute timer runs out turn it over. When the 4 minute timer runs out again the 7 minute timer has been running for 1 minute. Turn it over once again. When it stops the egg is done.
