Video Shows 200 Years of Temperature Data

Our planet is warming, and there’s no denying the fact. Well, at least not if you take scientific data and observations into account. Berkeley Earth Surface Temperature (BEST) study shows the average temperature of the planet has been steadily increasing. Researchers compiled a data set of temperature anomalies over 200 years to create a video that the average world temperature has been increasing at an alarming rate.

Student Makes Himself Tesla Coil Hat, Makes It Sing Harry Potter Theme [video]

When you’re wearing a hat that shoots bolts of lightning, we guess playing the Mortal Kombat – Harry Potter theme becomes fairly accurate. MIT student Tyler Christensen built this Tesla coil powered hat for himself as a halloween costume, but sadly it “blew up” before the Halloween weekend. We don’t know how Tyler solved his issues with a Halloween costume, but he had managed to grab this video before the hat went crossed the road, and it is seriously cool.
