I made up a jar of bubble solution to blow bubbles for my kids. Later I was in my bedroom checking the florescence of a rue extraction with the UV floodlight on my nightstand, when I had an idea.

I will add a gram of Mansked rue extract to my jar of bubbles (solution was made with water, blue dish soap and corn syrup). Then, at night in dark living room, I will turn on UV light and blow glowing bubbles.

Haha, you dog! That's hilarious. An unusual roa for sure.

You could also do this with the leftover water if you do a Harmala extraction, once the Harmalas/extract is precipitated out and filtered off, the remaining water will still glow, that way you don't have to sacrifice the Harmalas.

The bubbles will make a special, invisible mess that you can only see in UV!

Indeed, you should see my counters lol.

I once turned on the UV lamp for fun and games after I had been working a harmalas extraction. My hands were covered!!! I had washed with soap and water, didn't matter. Stays around a long time.

My worktops are permanently fluoro as well.

I might give the bubbles thing a try, 'just to entertain the kids'
