down the tube

Another way of saying that something is really going to pot -- when you say such-and-such is going down the tube, it is spiraling downhill extremely rapidly.
Man this drone flight is really going down the tube...O FUCK, There's a tree!!! (*CRASH!!!*)

chastity tube

n.

A rigid (or semi-rigid) enclosed tube that slides over the penis, interlocking with a rigid ring that slides over both the penis and testicles. There is usually a hole at the tip for urine to pass through to allow for long term wear. Once locked in place, the tube prevents the wearer from obtaining an erection or receiving traditional male genital stimulation.
Becky: It bothers me when my cuck husband Mike gets a boner. I'm never going to touch it so it's pointless.

Veronica: I know, like as if any girl would want to touch or see THAT. It's like tiny and stuff.

Mandy: Why don't you get a chastity tube for him?

Veronica: Like, what's that and stuff?

Mandy: There's a ring that goes around his junk and a tube that covers

his little pee pee. When you connect them together, he can't get another useless stiffy.

Becky: That sounds perfect!

NMR tube

An NMR tube is a tube used in NMR Spectroscopy (used to detect molecule structures depending on peaks on a graph). Cleaning it usually uses acetone or dichloromethane and getting rid of it involves vacuum and maybe IR lamp. Organic chemists sometimes send samples to an NMR lab to get it back with the graph and detect if they got their product.
Steve: I cleaned the NMR tube with acetone.
