Competition Four

This week, we are giving away prizes for the most wicked techno-solutions that you can come up with. The prize, as always, an original MiW labcoat with the lads' very own scrawl on the back.

Tell us how you solved a pesky little niggle - it can be domestic, school or work related, travel or space inspired, anything, anywhere, just as long as you built a machine to solve it. We will award prizes for the weirdest, most innovative, the savviest and generally most MiW-worthy of your solutions.

This competition is now closed.
