For those who missed it, Channel Four’s recent ‘Derren Brown Investigates…’ can be seen online here, and features my good self chatting about cold reading. I have a feeling you are the sort of person that will enjoy the programme.
OK, to the puzzle…..today I have to make dinner and have to boil some pasta for exactly 9 minutes. However, I only have two hourglasses. One of them measures 7 minutes and the other measures 4 minutes. Can I use the hourglasses to time exactly 9 minutes?
As ever, please do NOT post your answers, but do say if you think you have a solution and how long it took. Answer on Monday. Make the most of Saturday. It is due to rain on Sunday.
