You know what's really annoying? Teenagers. Even more annoying? Teenagers inventing legitimately useful things and getting awards for it. Meet Alexander Kendrick, the 16-year old inventor of a new low-frequency radio that allows for cave-texting, which isn't some fresh new euphemism, it just means people can finally text while deep underground. How deep, you ask -- well, Alexander's team of intrepid explorers went far enough (946 feet) to record the deepest known digital communication ever in the United States. What you see the young chap holding above is the collapsible radio antenna, though plans are already afoot to ruggedize and miniaturize the equipment to make it more practical for cave explorers and rescuers. Way to go, kid.
