England's longest zip wire to open at the Eden Project Visitors to the popular Cornish attraction, which is best known for its giant "biomes" that house a variety of exotic plants, will be able to ride the zip wire from Saturday. They must pay £5 in addition to their general admission ticket, while those not wishing to explore the rest of the site must pay £10 to ride the zip wire, which crosses the entire 35-acre site. The ride lasts around a minute. Gaynor Coley, the Eden Project's chief executive, was one of the first to use it during an inauguration ceremony today. She was joined by circus performer Marco Fiera, who took to the zip wire on a Penny Farthing bicycle. Riders must weigh between 40kg and 120kg, and must be at least 1m20 in height. Those under the age of 14 must be accompanied by someone over the age of 16, and those under the age of 18 require parental permission. See www.edenproject.com for more information.
