The Discovery Power Welder's sales pitch is fantastic, and worrying: "discover the power to make and create with the tool that safely welds plastic to plastic." And sure, the kit comes with specially-crafted parts that'll let your little-ones knock together a plastic dinosaur, plane or car. But what happens then? Do they start tackling their Lego collection with it, or decide to weld your iPod to your vacuum cleaner? Ok... so it's battery powered, and probably doesn't get all that hot, but we know just how "inventively naughty" kids can be. For just $30 this could allow your children to fuse your credit cards into one lump, never to be used again. [Product page via Random Good Stuff]
