Episodes List

Ep.1 Toilet Paper

Air Date: 2025-01-07

The battle for bog roll during the Covid 19 years showed us just how much we Aussies value the stuff. In this episode Dr Karl lifts the lid to discover how recycled toilet paper is made at the Encore toilet paper factory.

Ep.2 Chocolate

Air Date: 2025-01-14

At the Haigh's chocolate factory, Dr Karl gets the full Willy Wonka experience of how this sweet treat is made. Following it from bean to bar he discovers that the future of chocolate is in jeopardy.

Ep.3 Ginger Beer

Air Date: 2025-01-21

Dr Karl takes a peek inside the Bundaberg Ginger Beer Master Brewery. From the ginger farm to the packing line, he examines how this iconic soft drink - made from a spice and then fermented - is produced.

Ep.4 Cricket Balls

Air Date: 2025-01-28

Dr Karl visits the Kookaburra Sport cricket ball factory in Melbourne and learns how this global symbol of Australian sport is crafted from humble beginnings.

Ep.5 Lollies

Air Date: 2025-02-04

We know we shouldn't, but most of us can't resist the temptation of a lolly. At the Allen's factory, Dr Karl steps onto the factory floor to see how Snakes Alive are made - spoiler alert, the most popular flavour is red.

Ep.6 Cheese

Air Date: 2025-02-11

In this peep behind Bega's factory doors, Dr Karl learns how cheese is made... and it would appear that he knows more about String Theory, than he does string cheese.
