Martin you suck. Find something and post it. I mean, Jesus Christ, you let TC take all of your pride. Try to redeem yourself a teeny little bit by making a contribution to the thread.
Nope I didn't know it was hydroblomater I don't even know what that is. It does look an item used to calculate the density of liquids, but lots of things look like that.
A hydrometer is used to measure the density of liquids. I don't care if you don't know the exact name of my item is, if you can describe one of its intended uses that is good enough for me. Go already!
We should wait until somebody gets the last one. I dunno what spatial gravitas or darnsity is, if I did I could identify your mystery item. Is it a counterweight or something used to train canines for the cops?
