2. Programs from series

The same basic rule applies to building a cubby as building a house - measure it three times, build it once. This program explores the use of measurement when designing something, and touches briefly on the concept of building to a scale. We visit an architect's office and see the role of computers in modern building design.

How do you design a meal that meets certain criteria? This program looks at the role recipes, ingredients, utensils and culinary flair all play when it comes to preparing food. We follow the methodical steps taken to make a chocolate cake and demonstrate the correct use of cooking utensils.

Can we stop wasting food scraps, have a green thumb and keep worms happy and healthy all at the same time? This program shows that the answer is clearly "yes"! One of nature's perfect ecosystems is explored in this program as children set about building the ideal worm farm.

How do you design a toy for a baby? And what sort of toy would appeal to a child who can't see very well? While Flyn embarks on a mission to make a new toy for a bored, bed-bound Dodly, we explore some criteria for designing toys for certain users.

Music may be the elixir of life, but just how do instruments make sounds? Spurred by Dodly's mission to come up with sound effects for Flyn's adventure story, we begin by looking at some common household objects that can be used to make sounds.

What keeps a boat afloat and what role does its shape play in helping it to move? The quest to answer these questions leads us to investigate a range of possible boat building materials, including fibreglass, which we see sprayed into a mould then removed as a hardened shell.

Why do we put food into containers? And why are these containers all so different? The need to match the package to the product is explained and illustrated using a range of different foods. We visit several food production and packaging plants and see the care taken to ensure the products reach consumers intact.

Where would we be without bags to help us carry things? In this program we learn how a well-designed and properly worn bag can make everything from carrying school books to picking fruit easier. We look at some reasons behind the choice of bag making materials and visit a plastic bag factory to see how tiny beads become bags.

This program looks at all the different situations in which people wear headgear, from competing in cycling races to working as a welder or in a busy commercial kitchen.

We all like to play on playground equipment, but what makes them fun and safe? And how do those moving parts on seesaws, swings and flying foxes work? While Dodly goes off to design his dream playground, we visit others and take a close look at the materials used and how some parts work together as a system to provide movement.

How often do we stop to take a good look at how a bridge is constructed? This program examines the different forms bridges take and explains some reasons for these differences, such as the nature of the terrain they traverse and the weight of the loads they carry.

Technology used in the recording of sound is ever changing. In this program we begin with a familiar scene of sound recording - the telephone answering machine. From here we visit a post-audio studio to investigate the use of computers for adding recorded sounds to television programs.
