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  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.

"I thought the toilets were gross and they lived up to what I had heard about them.
"I particularly 'enjoyed' the giant trench - although I must say it was quicker to go in than the others.
"I'm keen to try this. It's always a problem going to the loo at festivals, you don't want to miss the music and so you hang on and then by the time you get there you're busting and there's a huge queue."
How it works: The double plastic bag contains a pouch of dry crystals which swell to form a solid gel when liquid is added.
The top of the bag then seals over the lip and the bag can simply be thrown away.
"We are aiming it at festival goers because they have to encounter unsanitary situations," says Go Bag's Carl Rees.
"It's small, compact and easily disposed of - and you can use it in a tent which is better than stumbling around the campsite in the dark."
The Go Bag is currently in use by the US Army and in theory each bag can be used up to three times before disposal.

"This is a great idea for Glasto. I lost my expensive Maglite torch in a Glastonbury toilet last year - it fell out of my pocket in the dark and going in to get it just wasn't an option.
"In the middle of a huge, huge crowd, taking off to the loo and then trying to find your mates again afterwards can a bit tricky - this is mainly why I went for the bag device. I can picture having a right giggle in the middle of the Pyramid stage audience whilst I'm weeing into a bag!"
