April fool jokes are funny. But this one takes the cake. It's called the Wi-Fi speed spray and this revolutionary product enhances your wi-fi transfer rate by cleaning the data path between you and receiver.

From the website "The patented formula in WiFi Speed Spray™ is the result of years of scientific research and testing. Simply spray the area around your computer. Usually five or six sprays is all it takes. As your computer sends data, each bit also carries hundreds of invisible WiFi Speed Spray™ "scrubbing" molecules."  

Haha, we are still rolling on the floor on this one; must read, click on the check it out link at the bottom of this post to read. On the related note, though this isn't increasing your Wi-fi speed a 'pringle can' could.. How? Google "Pringle can Wi-fi" for that.
