From the Ted Talk by Charles Wallace and Sajan Saini: Why a sausage can do what your gloves cannot
Unscramble the Blue Letters
In 2010, South Korea experienced a particularly cold wtiner. People couldn't activate their smartphones while wearing gloves, so they began wielding sncak sausages— causing one company to see a 40% rise in sausage slaes. So, what could sausages do that gloves couldn’t? In other words, how do touchscreens actually work?
In 1965, the first ever touchscreen was invented to help British air traffic controllers efficiently update flight plans. However, the technology was too unwieldy and expensive for widespread use. Over the following decades, engeneirs further delevoped this technology and experimented with alternative knids of touchscreens. Soon, resistive touchscreens dominated the market. But then, in 2007, Apple released the first ionphe. It was a breakthrough, yet it functioned using the same principle as the first touchscreen: capacitance. naodways, capacitive and resiivste touchscreens are two of the most common types.

Original Text
In 2010, South Korea experienced a particularly cold winter. People couldn't activate their smartphones while wearing gloves, so they began wielding snack sausages— causing one company to see a 40% rise in sausage sales. So, what could sausages do that gloves couldn’t? In other words, how do touchscreens actually work?
In 1965, the first ever touchscreen was invented to help British air traffic controllers efficiently update flight plans. However, the technology was too unwieldy and expensive for widespread use. Over the following decades, engineers further developed this technology and experimented with alternative kinds of touchscreens. Soon, resistive touchscreens dominated the market. But then, in 2007, Apple released the first iPhone. It was a breakthrough, yet it functioned using the same principle as the first touchscreen: capacitance. Nowadays, capacitive and resistive touchscreens are two of the most common types.
