Mashable's "10 Innovations That Improved the Word in 2013" list is out, and some of the innovations you have to see to believe.

Topping the list at number one is the lab grown hamburger. Yes, you read that right: lab grown. It may have cost $330,000 to develop, but thanks to a major investment from Google co-founder Sergey Brin the world saw its first lab grown burger in August. It took researchers at the Netherland's Maastricht University five years to develop the patty, which was created using 20,000 protein strands grown from stem cells taken from a cow's shoulder. Hello, scientific solution to the increasing global demand for meat!

Google Glass is number two and the beef tendon condom is a strong number three, though the invisible bike helmet that doubles as an airbag at number eight is impressive. Hovdig is a discreet helmet cyclists wear around their necks that inflates like an airbag in the event of an accident. While skeptics think this option sounds a bit riskier than a traditional bike helmet, Hovdig claims its not-so-noticeable helmet offers the best shock absorption in the world.

Just about finishing out the list at number nine is a tremor-reducing spoon for people with Parkinson's.  Check out the entire list.
