Here are a couple of examples of uses for this marker:

Great to stop switching: If you sell items and if there is a possibility for returns, you can mark your items with the invisible ink marker before the item is sent. If a return is necessary, you will be able to detect if it was the item that you sent originally by checking your marks that you made with a black light. This is a great way to head off switching.

Excellent tool to curb Theft at Colleges: This is a proactive approach to curbing crime.  Schools are welcoming students to use this marker to write their drivers license number or social security number on hand-held computers, bicycles and other often stolen items.  The ink markings enable police to identify the owners of stolen items recovered from pawn shops or other locations.  This is also good to mark your books.  

Taking an item in for service and want to be sure that your receive the same thing back: If you were taking an item in for service and you want to ensure that you receive the same item back. You could mark it in the invisible ink and check the item with a black light when it is returned to ensure that you received your original item.

Great for special effects: One of my friends has Model Trains. When he found out about the markers, he decided to create special effects on the trains and some of the buildings with the invisible ink marker. He put several large black fluorescent lights in his train room. When the normal lights are turned off and the black lights are on, the visual effects are very cool.

Great way to write passwords: You could write your password on your desk right in front of your computer or on a separate piece of paper undetectable to others. Only you would know where your wrote your special passwords to recall at a later date with a black light.

Great for level control: If you think that underage children in the house are drinking your liquor, you could mark the level of the bottle with the marker and illuminate your marks with a black light to find out if any has been consumed by others.

Great for marking Tools: Do you work in an environment that you may need to share your tools. Ever have a problem with the person that borrowed the tool claim that it is their tool? Now you can prove it is your tool. You can mark your tools with the invisible ink marker and when that person says that it is their tool, you can pull out a black light and illuminate the area that you marked proving that it is your tool.

Great for School Science experiment: Use this for your next science experiment or project.

Great for practical jokes: I attend a bachelor party for a friend, we all wore "Special" white shirts and went to cosmic bowling. We wrote several comments on the back of his shirt and everything showed up under the black lights at cosmic bowling. It took him a while to figure out why people were making comments to him regarding the wedding.

Great for catching thieves: If you know that you have a thief and know who it is (or not) and would like to catch them red-handed, this would be a great way to mark cash or other items.

Great for a Contest: You could mark a Million Dollar Bill or more with the invisible ink marker. Do not tell anyone how it was marked. Pass the Million Dollar Bills out to everyone. Let them know that one or more were marked and whoever has possession of one of the special Million Dollar Bills wins the prize.

Good alternative to etching tools: The beauty of the invisible marking is that a person does not know that the item is marked. Markings from an electric engraver permanently scars the item let alone if the item is stolen, the marking can be filed or sanded off. When a product is engraved, it looks terrible, like a two year-old scribbled on it. If the owner marked a camera or stereo and wanted to re-sell it at a later date, the item would be worth less since it would have engraving all over it.

Great for showing your loyalty to Blue Man Group:  I attended the Blue Man Group show a couple years ago when I was in Vegas at the Luxor.  I noticed they had black lights incorporated into their show.  We visited Las Vegas again in March 2004 and went to the show again.  I wrote a message on my blue man group black shirt using the ultra-violet ink.  I wrote Blue Man Group Rules.  It was noticed by one of the blue men when they walked into the audience.  My shirt got me a little more attention than I wanted.  During the show, I got a marshmallow thrown at me along with a Jell-O mold.  It was a fun time anyway.  If you are ever in Las Vegas and get a chance to see Blue Man group, I whole heartedly recommend the show.  It is worth the $90 they charge for the show.
