The answer to last week’s challenge is. Q: Professor Frink was trekking through a remote jungle when captured by logic-loving cannibals. He was brought before the Chief and told, “You may now speak your last words. If your statement is true, then we will burn you at the stake. If your statement is false, we will boil you in oil.” The Professor thought for a moment then made his statement. Confounded, the cannibals realised they could do nothing but let him go. What did he say?

A: “You will boil me in oil”.




To think more laterally and to drive more efficient and outcome-oriented meetings, join us for our Six Thinking Hats Facilitator Training on Dec 6 in Melbourne.


This week’s lateral thinking challenge is.

Q: If you put a coin in an empty bottle and insert a cork into the neck of the bottle, how can you remove the coin without taking out the cork or breaking the bottle?

For the answer and for next week’s thinking challenge, tune in next week.




Good Luck!

  1. Richard :

    Probably sulphuric acid will leave the coin relatively intact but will dissolve the cork and erode some of the mouth of the bottle. Though I suspect your answer is better than this.
