A few toilet roll tubes can be turned into a cryptex-style puzzle, that hunters must use to spell out the clue.
To make the puzzle you will need at least 3 toilet roll tubes. Cut two of the tubes down their length and tape them up again so that they are now small enough to slot into the uncut tube. This uncut tube is the outer tube, so you will need to carefully cut little windows in the tube so that the inner tube can be seen. Slot each inner tube into the outer tube and write a letter of your clue onto the inner tube within each window. Take the inner tubes out of the outer tube and write some random letters on them.
The hunters must slot each inner tube into the outer tube and rotate it to line up the letters through the windows.
