Yep, it's a hypospray and yep, it's a prop. But it's special for two reasons.

#1: it's not a 'commercial' prop. By that I mean it isn't currently a mass produced item. I didn't buy it from a toy company or prop company like Roddenberry.com.

#2: It was a gift 'of the heart' from a shipmate, Scott Nakada, who makes custom props for sale [and some for roddemberry.com to resell] from his store . http://www.xscapesprops.com/ Scott knew I've always wanted one and it was going to be a project we were going to work on together [he was teaching me how to design, mold, cast and paint props], but a relocation move came up suddenly and I thought we'd never get to it. At the last ship's meeting I was able to attend, he gave this to me.

I finially found the camera and snapped a quick picture. Believe me, the picture doesn't do it justice.
