April Fool's Day usually brings a host of silly products to tempt gullible internet users. From Google Gnome's outdoor home assistant, to Google Cardboard for your Chromebook, to a selfie stick for a tablet. Google also has PacMan, which you can play on Google Maps. You can also see a data center on Mars complete with solar panels. And that's just on Google.
Think Geek always has some silly ones as well. A Hot Pocket Sleeping Bag, a "Where's Barb?" children's story from Stranger Things, and the Bicycle mounted Horn of Gondor.
