The U-Fizz makes nearly any drink fizz like soda, and all you need is: a “box of baking soda, some vinegar and a couple of soda bottles.” Available now, priced at $6.95.

That gets me thinking…I wonder what would happen if you dared to put some Diet Coke and Mentos in this contraption? Maybe the world would explode.
