However, out of all the pens I've seen, my personal favorite is the UV light pen. Just what is a UV light pen you ask? You may have seen them in movies or your local spy shop, but these pens have special ink that can only be seen under UV light. What happens when parents supply their children with these things? You have kids writing secret notes and messages in class, most likely about their teacher. It's like having a classroom full of mini spies. How do you combat this? You fight fire with fire and buy your OWN UV light pen!
I was looking around for these pens for the longest time and finally found them in a smaller stationary shop. For 1000w ($1USD) you can have as much fun as your kids. At times, I will randomly shine my light on their workbooks in search of hidden messages written in Hangul that I can't read anyways. Have a kid driving you nuts? Draw on their book with this pen! That really gets them going--especially when they don't have their own pen to decipher the message. Joke's on you, kid!
Here's my UV light pen. As you can see, it's all pimped out with the words "project milk" and a few phrases about how wonderful cow's milk is. It even looks like a cow. The UV light is usually built into the lid of the pen:
Here is UV light in action...pretty cool, huh?
...and this is your job for today:
I have never seen these pens back home in Canada. Have you? If you have, let me know!
