For the non-Aussies on board, at first sight, Tim Tams appeared to be identical to the British McVites's Penguins and indeed the concept is the same. However, Tim Tams are 'double-coated' with chocolate and this could be source of their strength in the Tim Tam Tea challenge. The rules of the game are to bite off each end of the biscuit and then suck hot tea through the centre before the whole thing collapses into the bottom of the mug. The winner is the person who can draw tea through the biscuit in the fastest time. (You don't have to drink all of the tea by the way).
For the next round, we substituted Penguins for Tim Tams and were disappointed to find that they crumbled too quickly and unfortunately weren't up to the job.
So thanks Dutchie for bringing Tim Tams on board and idle moments afloat will never be the same again.
