The Slow-Mo Guys Visit GE’s Labs

The Slow Mo Guys are Gav and Dan, who film their usual antics using a super slow-motion camera. They were recently flown out to General Electric’s labs to conduct some actual “scientificy” experiments and film the results at 2,500 frames per second. In the first experiment, the pair mess around with a superhydrophobic surface developed by GE that repels water at a nanoscopic scale. They also play with a liquid made up of nanoscopic iron filings, which behaves like a magnetic liquid.

In the second experiment, Gav and Dan play with MEMS (Micro Electromechanical Systems) technology which can be used to open and close circuits up to 10,000 times per second.

Finally, in the third video, the GE researchers demonstrate a process called “cold spray”, in which metal powders are sprayed at high velocities to build a part or add material to repair an existing part.
