here one of my black light. As you see the bubbles liquid is running down in front of me. It do have noen paint in it so it will run like this. You see the purple in front that another "Liquid motions" going on ; that a bubble. The bubbles did not glow like I thought it would but then i find another recipe for color bubbles to blow. it do not call for neon but it do call for poster paint which i used but it was noen poster. so you get two "Liquid motions" here ; the drip and the bubble as it get bigger

what you see is not what you know; it in your face
