I thought I saw a contrail..couldn’t see the vehicle itself, but I thought I saw a small, thin cloud perpendicular to the rest.
This is pretty cool, though!

Once the wire connects to both the + and - terminals of the battery current starts flowing which produces a magnetic field, this field pushes against the magnetic field of the magnet causing it to spin.

3D Printed Photographs
Instructables walkthrough from on converting black and white photographs into 3D printed images complete with relief texture:
The 3d printer in our office (an Objet Connex500) prints with a rigid, semitransparent white material that can be used to create these unique black and white photographic prints. These prints may be indecipherable when viewed from the side, but when backlit with a diffuse light, they recreate images with surprisingly high precision and even add some subtle dimensionality and texture to the scene.
By varying the thickness of a region of this semitransparent print you can control the amount of light that is able to pass through, thereby controlling the brightness (thinner regions of material will appear brighter and thicker regions darker). In this project, I’ve mapped each individual greyscale pixel value of an image to thickness, allowing me to precisely reproduce any greyscale image. The photos I’ve printed include an adorable picture my mom took of our cat Teddy (fig 4), Saturn and its moon Titan taken by the Cassini space probe (fig 5 and 6), and a huge print (19x16”) of Mt. Williamson by Ansel Adams (fig 1, 2, and 3).Read how they were put together here

Wartenburg Pinwheel corona
This is a Wartenberg pinwheel charged to a very high voltage by an industrial power source. Under these conditions, sharp points exhibit corona discharge into the air, with violet light streaming away from the pins. At a guess I’d say that the voltage was 30-50kV.

NASA’s GROVER Debuts On Greenland’s Ice Sheet
NASA’s new Earth-bound rover began testing on the Greenland ice sheet this week.
GROVER, which stands for both Greenland Rover and Goddard Remotely Operated Vehicle for Exploration and Research, is an autonomous, solar-operated robot that carries a ground-penetrating radar to examine the layers of Greenland’s ice sheet. Its findings will help scientists understand how the massive ice sheet gains and loses ice.
The GROVER team, led by glaciologist Lora Koenig from NASA’s Goddard Space Flight Center in Greenbelt, Md., arrived in Summit Camp, the highest spot in Greenland, on May 6, 2013. After loading and testing the rover’s radar and fixing a minor communications glitch, the team began the robot’s tests on the ice on May 8, defying winds of up to 23 mph (37 kph) and temperatures as low as minus 22 F (minus 30 C).
The GROVER tests will continue through June 8. GROVER, a prototype, was first developed in 2010 and 2011 during summer engineering boot camps at Goddard, before further refinement, with NASA funding, at Boise State University. Its trial in Greenland will also serve as a test of using rovers in harsh polar regions to gather data.
