I love StaStaX! You can have it save the individual files and create a video with it too. #astrophotgraphy

Understand. I think once you are doing 2D momentum they have seen that you have to take the mass into account. It would be nice if you could add mass to the hover pucks but they barely levitate themselves as it is. I wonder if you could reduce their mass by removing bits of plastic and foam.

At my 39 N latitude, green is usually seen as a low glowing fringe in the distance. On 11/11 it was more dynamic as this time-lapse video using 4s exposures shows. I think it is a strong substorm that must have been amazing for those to my north. It is reflected in the lake. #astrophotography

I wrote this Smart Cart sense and control activity: www.pasco.com/resources/la... My favorite was a Red Light/Green Light program. It was a little over the top because I had access to all the PASCO equipment. It has a Smart Cart with a motor, light sensor, and wireless light source. #ITeachPhysics

I was able to upgrade my room for an extra 3$/night for a High Roller view room. I took this time-lapse from our room at the Westin 8 years ago. It takes 30 min to rotate in real time. With a diameter of 158 m, what is the centripetal acceleration of a passenger? #ITeachPhysics
