[protection] how long must the container be

German researchers are developing a type of spray can into which the man inserts Percy, then latex is sprayed on from nozzles on all sides - a bit like a car wash, as they put it, all within about five seconds. However, before it can be sold in shops, the firm who’ll make it must ensure that the latex is evenly spread when sprayed, as well as optimizing the vulcanisation process.

They hope it will be available in different strengths and colours and on the market by 2008. The spray can would likely cost about 20 euros as a one-off purchase. The latex cartridges - sufficient for up to 20 applications - would cost roughly 10 euros.

So – what do you think? Personally it sounds quite good but the fear of emasculation by a guillotine type malfunction might put many off. And what if you weren't ... er ... excited at the point of application?
