How do touch screens work? - Science Short
How does a piece of glass know where your finger is? Brooklyn, aged 10, from Cammeray has an excellent question: how do touchscreens work?
Join Christie as she peels back the layers of this everyday technology, uncovering see-through electrical pathways, glass that gets a 400-degree salt bath, and the surprising role your own body plays in every tap, swipe and zoom. Discover why gloves and water can confuse a touchscreen, and how a cracked screen can sometimes keep working.
