Scotty reckoned he could manage the job in nine pours by filling and emptying pails, but he still wanted to get to half of Jim's estimated figure, so he thought a bit harder. His original solution is shown below.

  • Fill the 5 litre pail from the 8 litre pail
  • Fill the 3 litre pail from the 5 litre pail
  • Pour the 3 litre pail into the 8 litre pail
  • Pour the 5 litre pail into the 3 litre pail
  • Fill the 5 litre pail from the 8 litre pail
  • Fill the 3 litre pail from the 5 litre pail
  • Pour the 5 litre pail into compressor 1
  • Pour the 3 litre pail into compressor 2
  • Pour the 8 litre pail into compressor 2

If you can find a valid solution in seven pours or less, then email your answer, your name and address to puzzled@star-ref.co.uk. The first three valid answers received by Friday 19th February will receive an OWL energy monitor.
