Guys, we’ve found a way to keep your girlfriends happy. No, we haven’t invented magic stretching machines or free Viagra, we’ve stumbled upon a way to stop those late-night toilet breaks from causing arguments and accidents in the morning.

The lav nav is a great  product that will guide even the sleepiest members to the intended target. Fitted to the underside of your toilet lid, small LED lights sense someone approaching and act as a landing strip to ensure the successful meeting of pee and porcelain.

Think that’s clever? There’s more! Not only does the lav nav sense approaching mischief makers, it will also glow red when the toilet seat’s down, indicating that release suspension should occur until the lid is lifted up and then the green light indicates go. Fab! Who would have thought a gadget could be so physically and socially useful? Even if it’s not your birthday, buy yourselves a present lads.

We all know that we should be doing more to help ease our effects on the environment so we’ve decided to bring you Green Piece - a look at the latest green gadgets around.

This week we’ve stumbled upon the "Wash Up", courtesy of GadgetLite. Ever wondered how all of that water from your washing machine could be put to good use? Wonder no more because Sevin Coskun has designed this unique washing machine/toilet combo.

The washing machine is stacked on top of your toilet so not only is it easier to load but it also stores all of the water used to clean your clothes in a reservoir that can then be used to flush the toilet.

We use up to 120 litres of water when we wash the average load of washing and 9.5 litres when flushing the toilet so this is a great green gadget. Opinions are pretty mixed on this so let us know what you think!

Those who find the concept a little disturbing can still do their bit by investing in an energy efficient washing machine.
