Have a hankerin’ for milk and Pepsi but hate Pepsi? Well, if you’ve been suffering through the ultra sweet taste of that suspect combination just to get bubbles in milk, it’s time to let science lead you to better living. The U-FIZZ Drink Carbonation Kit consists of little more than a couple of plastic tubes and a hose (luckily with a $6.99 price tag to match—good job ThinkGeek), but manages to turn any beverage into a bubbling fountain of nose-tickling goodness. Whether it be juice, coffee, tea or the aforementioned milk, your favorite beverage can now be made better. How? Science. By using baking soda and vinegar to produce carbon dioxide, the gadget captures the escaping gas and puts it into your drink. Better living through chemistry, indeed.

The Recording Can Fridge Guard is an inconspicuous looking device capable of answering an age-old question: Does the refrigerator light really turn off when the door is closed? Simply record a message and stick it in the fridge. It is cleverly camouflaged as a cola can, so any fridge gnomes (I suspect) will not be distracted as they go about their light-turning-off duties. When the door is opened, and light hits the can, your message will play. Pretty simple stuff; if you don’t hear the can talking to itself when the door is closed, well then, the light is indeed off.

Of course, you could use the can to leave recorded shopping reminders or encouraging words for a dieter, but where’s the fun in that? I can’t think of any better way to make sure the light goes off other than opening and closing the door really, really fast.
