I can crack walnuts between them, and have the aim of that woman in The Full Monty..... however, my worry would be where do you put them when they're full?
Hi den great idea with a bit of a flaw.
I was interested in this bit of the article. "It consists of a pad which is in a small plastic bag. The user wees into the bag where the pad captures the liquid and turns it into a gel in a matter of seconds"
Which is great in theory but then still leaves you with a bag of human waste to get rid of which will ultimately end up on the floor.
the bags of powder / gel are similar to the ones you get for portable pottys for kids. As said, you then have a bag of waste to take home with you, which could be slung on side of road or in fields.
I am hoping that those people who would buy and use them when on car journeys would also take them home to dispose of. But at weekend camping and at festivals, i cant imagine anyone building a "pee-bag" wall like they often do with beer cans and binning it in correct manner.
