Light Painting

In testing my new camera, and using up my glow sticks, I had no real concept of what I wanted to do in light painting, then I thought about the slinky effect,, anyone remember the slinky?

Thanks for following.. sets up for each shot below.

Lighting of the jar and background was done by opening the shutter, turning on studio light for 3 seconds, covering my lens, turning off all lights and uncovering the lens as I used the glow stick

ISO 100

F8.0

Lighting of the jar and background was done the same as the photo above. The only difference was that I turned on studio lights for 1 sec instead of 3.
