So, got the Chief in today…it’s great, wonderful, yada yada whatever. But, I’m curious as to what in the heck these things are that came inside the box. Seems to be a plastic tube with some kind of viscous liquid, and then floating within that, a second plastic tube that appears to be filled with sand or something that I can see shaking around in there a little. I have 4 of them.
I guess the only thing that comes to mind is maybe flowable silicone? Seems odd, but I can’t think of any other yoyo related thing this could be…or maybe I’m just not considering the obvious.
