Who would have thought that someone would actually take a bunch of Lego bricks and turn it into something dangerous? Aren’t these things supposed to be kid-friendly? Well, the inevitable happened, resulting in what you see here – the Lego circular saw. It will actually spin a real blade, but thanks to a built-in safety precaution, the blade tips were removed (sounds like Ikea blunting the knives on display) with it being programmed to stop whenever touched. Great idea, since you know how Lego draws kids to it like bees to honey. If you are interested in making one for yourself, the instructions are here to occupy your weekend.
