Tales from the Workshop…

Tales from the Workshop…

In this first instalment from our new series ‘Tales from the Workshop’, we’re going behind the scenes with our Exhibitions team as we gear up for the opening of our brand new exhibition ‘Food’, opening at the end of July.

Recently we’ve been out and about at Make Sundays Special, Food Connections Festival and at the Daylesford Summer Festival – we’ve been testing some tasty science experiments and also giving people a sneak peek at some of our exhibits as we took our prototypes out for the first time.

Make Sundays Special

Pop Goes the Kernel! 

One of the key exhibits for Food, and one that you might have helped us test during the Food Connections Festival, is our amazing popcorn bike machine! This exhibit showcases how to pop a popcorn kernel using a bit of old-fashioned arm cranking power combined with some high-tech LED lights!

Food Connections

On our last visit to the workshop, it certainly looked and sounded like an engineering challenge with so many variables to contend with.  The team have been devising an ingenious solution that makes sure all of the all-important energy is directed in the right way – to making corn pop. At the time of writing, the workshop team had trialled and tested over six different set-ups; science and engineering in action!

Modifications have involved changing the position of the lights and lenses to ensure even coverage of the kernel, while the trough ensures kernels are held in the same position.

Next we looked at making sure all of our visitors could pop their own corn so we made changes to the hand crank. The latest update has involved changing the white LED lights to blue, as blue light is better absorbed by the yellow kernel.  This maximises the amount of light energy that gets absorbed, all helping to pop that kernel!

And after seeing it in action the workshop team have a couple more changes up their sleeves…
