Invisible Blue UV Reactive Water Dye

The media could not be loaded. Initially I was disappointed. I flashed my UV flashlight at the bottle and it was green. But to my surprise when I added it to the water and used the same flashlight it was a beautiful blue. Super cool. The bottle next to it with the red is the red from the same company. The two in the middle were tinted using highlighter on the last one is the old Primo chill UV green.

For Christmas, I got my son, who is a huge Fallout fan, a Nuka Cola bottle with the intent of making it glow like the Nuka Cola Quantum bottles in the game. I rigged up a UV nail polish setting light puck to point up in a base. Filled up the bottle with tap water about about 25 drops of this Invisible Blue UV dye and put the bottle on the base. When I turned the UV light on, it glowed exactly how it does in the game!! I can't wait for my son to see this when he gets home for school. I have hardly touched the total amount in the bottle, so I'll have plenty more in the event that the current dose fades over time. Very happy with the results!

I purchased this to add to mix strings to create something that glows under black light.It wasn’t until I got the product and was able to go to their website where I found it was not safe for consumption.If I’d known on the Amazon page I probably wouldn’t of.net, however it worked exactly hours it’s suggested

Actually incredibly effective and totally invisible when not under blacklight. I will say, though, it seems you have to use a pretty high concentration.

Good uv die. Same as what would be inside a uv marker. I used this to make transparent uv paint for an airbrush. I had a hard time getting this to mix with water, it would just sink to the bottom like a heavy oil. Also wouldn't dissolve into paint thinner, however acetone finally did the trick. Worked great once mixed with acetone and used in airbrush.

I was very excited to use this and 2 other colors for a haunted house. One drop did very little. I ordered 3 colors, and they sent me 2 labeled blue - except one of those colors was CLEAR. The other blue came out light green after I used about half the bottle. After a few hours, all colors were very pale. None fluoresced under black light. Very disappointed. I didn't inspect the bottle labels until I was putting the drops into the water. I gave a score of "3" for easy to use since you just put the drops in the water. But you might as well use food coloring.

Used this for a glowing bottle that sits on my shelf. Barely takes a few drops and lights up just like the picture. Doesn't take much light either. No complaints whatsoever.

Works very well with my photo projects. I got this color plus the green and red. You do have to be careful with skin staining but it isn't anything that can't be easily cleaned with soap and water. I use it with portable UV lights to create neat images having glow-in-the-dark water pour over models and it makes for some very cool pictures
