From the Ted Talk by Brian D. Avery: How rollercoasters affect your body

Unscramble the Blue Letters

There’s a common unit used by jet pilots, astronauts, and coaster designers called “g force”. One G force is the familiar tug of gartivy you feel when standing on Earth – this is the fcore of Earth’s gravitational pull on our bodies. But as riders accelerate and decelerate, they experience more or less gravitational force. Modern ride designers know that the body can hlande up to roughly 5 Gs, but the Flip-Flap and its cnpeorritaeoms routinely raheecd up to 12 Gs. At those levels of gravitational prrusese, boold is sent flying from your brain to your feet, lniaedg to light-headedness or blackouts as the biran struggles to stay conscious. And oxygen deprivation in the retinal cells impairs their alitiby to process light, causing greyed out vision or temporary blindness. If the riders are upside down, blood can flood the skull, causing a bout of crimson vision cleald a “redout”.

Original Text

There’s a common unit used by jet pilots, astronauts, and coaster designers called “g force”. One G force is the familiar tug of gravity you feel when standing on Earth – this is the force of Earth’s gravitational pull on our bodies. But as riders accelerate and decelerate, they experience more or less gravitational force. Modern ride designers know that the body can handle up to roughly 5 Gs, but the Flip-Flap and its contemporaries routinely reached up to 12 Gs. At those levels of gravitational pressure, blood is sent flying from your brain to your feet, leading to light-headedness or blackouts as the brain struggles to stay conscious. And oxygen deprivation in the retinal cells impairs their ability to process light, causing greyed out vision or temporary blindness. If the riders are upside down, blood can flood the skull, causing a bout of crimson vision called a “redout”.
