The Whiz
How it works: It's a reusable funnel which fits snugly against the body, meaning the woman can pee standing up, anywhere that a man could.
The Whiz is made from flexible anti-bacterial plastic meaning you can "pee, shake and stuff it in your pocket," says Marketing Manager Kate Pierrepont.
"When we launched it at the Isle of Wight festival [2004] there were women rushing up to us who were desperate for the loo. This device makes it easier and more dignified than squatting because you can't bear the queue."
Pierrepont recommends using the Whiz in a urinal or toilet if possible, to prevent pollution of local water courses.
