For all those Evil Geniuses out there...

Ever wanted to take over the world but haven't been sure how to go about it? Well, with a few household items, now you can! It's as simple as one-two-three.

Step 1. Get a fibreglass satellite dish and line it with 5800 small mirrors all focused into one spot. And just like that, you now have a solar death ray, capable of burning holes in paint tin lids, cutting a soft drink can in half, even melting rock and concrete! Serious, some kid in the States did just this and then presented it on YouTube. Check it out.

Step 2. Go find the Scientists who have recently made a paper clip invisible using calcite, use your newly created solar death ray to kidnap them, and get them to build you an invisibility cloak (apparently this new invisibility technique is only limited by the size of the calcite crystals, which can grow up to 21ft long so this isn't really a problem).

Step 3. You are now invisible and you have a weapon of destruction (presumably also invisible as a satellite dish walking around by itself would look a bit obvious). It's time to take over the world. Good luck. May the Force be with you.

Better hurry though as I imagine the military will be in on the action pretty quickly...
