A thread recently popped up on Reddit running down some mind-blowing technology people probably think doesn't exist in real life, but actually does.

Mind-controlled robotic limbs.
A 52-year-old quadriplegic woman has gained full control of a robotic arm with her mind, according to University of Pittsburgh professor of neurobiology Andrew Schwartz.
Jesus Diaz at Gizmodo explains how it was done: "Schwartz's team implanted two 96-channel intracortical microelectrodes in Jan's motor cortex, the part of the brain responsible for controlling the movement of our limbs. The results, according to the scientists, were uncanny. They were surprised by how fast Jan took control of the robotic arm."
Space shuttle thermal tile can be super hot one second, but safe to touch the next.
Check out this video from a Kennedy Space Center tour. The cube is pulled out of a 2,200 degree oven and few seconds later it's okay to touch.
