How to get liquid with bubbles running through surgical tubing?
I may just not be searching the right terms, but I can't for the life of me find a way to have colored liquid with bubbles in it run through surgical tubing. (Basically, the bubbles show that the liquid is flowing.) I've seen this effect in movies using smaller diameter tubing and also in larger tubing in the frame work of old style juke boxes.
For halloween, I'm thinking about a throwing a mad scientist party and using a black light lit fluorescing liquid In the tubing. Bonus points if it's portable for the costume!
And yes, I haven't really played with pumps before, so if most do this out of box, please be kind. :)
