Spooky Glowing Water....





Introduction: Spooky Glowing Water....

Looking for a new way to spook your trick or treaters? Maybe you have a haunted house that needs some added effects. Whatever your reason is, this is one way to creep people out.

I did this by accident when I was younger. I was playing with my blacklight and some highlighters (writing out secret messages and what not) and the marker I was using was starting to dry up. I usually just wet my fingers and use them to wet the tip, but someone had left a small glass of water on the table so I instead dipped it into there (kind of reminds you of a feather and inkwell). After a while the marker would start to go dry again, so dipped it again....and again. I decided to let the marker soak up some of the water in hopes that it would last a little longer so I placed it in the glass and switched over to another colored marker. After about 5 or so minutes, I looked up and saw the water "glowing" a little. I placed my light closer and it started to really glow. That's when I discovered that highlighters make really cool effects when used in water.

Here's what you'll need:
1. Highlighter marker
2. Glass of warm water
3. Blacklight
4. Scissors

Before I forget to add this in.... Warning: Don't drink the water unless you used non-toxic highlighters (even then it may not be a wise idea to do)

Step 1: Drain the Juices....

Make sure you have a glass filled halfway with warm water...

1. Take your highlighter apart so that you can get at the sponge.
2. Take the sponge out of the marker and cut off the plastic that surrounds it.
3. Drop the sponge into the water and watch as it absorbs the water while leaking out the ink.
4. After the sponge has absorbed as much water as it can, take it out and squeeze the contents back into the glass until the sponge is fairly dry.
5. Now turn off the lights and turn on your blacklight near the glass

    So how long will the highlighter ink last? I want to make a fluorescent mineral fountain for my Granddaughter for her birthday and hope I could send the water already done in a plastic sealed container would this work do you think? I am creating everything by hand so it will be unique only to her. Once she puts the water in the fountain will it just recycle and not lose its fluorescents? I am buying the blacklight to go with it.

    i need a glowing water that DOESNT NEED any other lamps ext....

    Mixing a bit of hydrogen peroxide with Luminol (careful, this is CAUSTIC !!! ) will give a bluish glow

    "blacklight" or more technically an ultraviolet light is a floriscent tube type light that radiates mostly UV light.

    It is used to draw insects to bug zappers (you may have seen some of them at restaurants and food markets), they are used at a lot of different party settings and are now quite common. They are also used to purify water, and other liquids.

    Here is a short listing of places that sell different kinds:


    its an ultra violet light it makes bright colors glow and makes other colors look darker

    very clever! :T

    Oooh! Our roller rink is all blacklight, so if you drew on yourself with highlighters it would make a really sweet effect. Thanks for the idea!

    Why do so many people not know how to spell "fluorescent"? Surely we can see that flour- is what you you make bread etc from... (pedant) L Also glow-sticks do not obey the laws of physics.... spooky

    LOL, I was just thinking that you can't get much glowing effect from something flourescent... ;) But, I'm sure we all got the point, and there are a lot of people with dyslexia and many who doesn't have English as their native tongue, and I bet many are challenged by both these things - so I normally choose not to comment on spelling. There is one exception though, when somebody chooses to write in 'SMS language' or something like that, that is awfully difficult to read, I guess especially for those of us who doesn't have English as our language. It is simply annoying having to read things out loud in order to understand what it says, so I think we owe eachother to write to our best ability. :). Oh well, that was OT, but I hope I'm forgiven... :)

    Tasteful response/comment. Good explanation of your position, stated respectfully. BTW, (by the way), the other response to your comment was sarcastic. I'm pretty sure this person knows what OT means, and the fact that you used two examples of SMS language in your comment was rather ironic. (LOL and OT)

    Hi Subvert, Thanks for your nice and constructive reply! :) I wasn't sure if the other response was sarcastic or not, so I chose to just reply... :) I see that when I used the term "SMS language" in my first response, I should have explained what I meant by it, as we obviously interpret that differently. That said I can see how you found my use of "LOL" and "OT" ironic! :) I don't see the use of these as "SMS language", but more as Internet- or E-mail acronyms/abbreviations, which I have thought of as something that has become quite well known for most over the years. Even if the person here who asked, probably meant it in a sarcastic way, I regularly on forums see people asking such questions, so it is obviously not something everybody knows (lots of new net users still). So maybe one should use these more sparingly, since there most likely for each person who ask, are many who don't even if they don't understand (after all, all most of us want, is to be understood as well as possible - which can be a challenge in writing! :) )? Anyway... What I meant to address when using the term "SMS language" wasn't these, but rather when whole sentences are (mostly) formed using short versions of words, as e.g. "U" for "you", "B4" for "before", "bcuz" for "because", "R" for "are", "Gr8" for "great", "tomoz" for "tomorrow", "soz" for "sorry", "ur" for "your" and "you are", "btwn" for "between" etc. Sometimes you on forums see quite long posts written this way. Until now I had only seen this called "SMS language", but now I see (on Wikipedia where I found a nice article on it) that it is often also called chatspeak, txt, txtspk, texting language or txt talk. The reason why I mentioned this, was that it is very difficult to read for many. I guess that the most used language on the Internet is English, but I wouldn't think that English is the first language for most people on the Internet. A lot of us has another language as our mother tongue. When maybe even long texts are written using such a "language", it is difficult - it pretty much looks like gibberish. The only way of understanding, is reading it out loud (or "out loud in your head"), but sometimes even that is difficult. E.g. if the person is using a more "advanced" form of this, as e.g. when "z" is used instead of "orr", some of the message might even be lost. I have no problems seeing that writing like that, especially for those who type slowly, saves a lot of time. But I think that it is really too bad to exclude a lot of readers. Sorry this got so long, a lot of text for a little clarification - but it is always nice to clear up a misunderstanding one has caused... :) Oh well... Enough on this subject (or should I say "Nuff Said!"? ;)) Have a nice day! :)

    u kno, i agree wit u. i hat ppl who use SMS language, cuz most ppl cant undrstand wat tey r sayin. (lol)

    Haha, good reply. It sounds like what you're saying is that LOL and OT are ok because they're really acronyms for another phrase, where SMS language is just shortened/abbreviated words. And that makes sense to me.

    wahts OT mean? i see it alote...{{{


    Hi, OT means "Off Topic"... :)

    what do u mean glow sticks dont obbey the law of phisics??
