Zips and Screen Printing
Maddie looks at clothes. She uses a special microscope camera to look at the zip on her hoodie. An animation shows how the slider works to pull the two rows of teeth together to close the zip. Next, Maddie visits a workshop to see how a dinosaur picture is screen printed onto a t-shirt. Her special microscope camera shows how a stencil, created on a screen, allows the ink to pass through and create the design.
