Get ready: There is some serious wow factor to this project. You will need a few special supplies for it, including a black light, which you can purchase from sellers like Amazon, as well as a highlighter pen you don’t mind sacrificing (hint: you’re going to cut it open). But armed with those items, kids will adore this project!
First, I showed Travis the black light, and how it works. Keep exposure to a minimum, because as a reminder, black lights use UV rays.
Next, we filled a clear vase with water, and set aside a few white flowers from a bouquet we’d purchased.
I showed Travis how the highlighter pen would look in the black light. He couldn’t believe the way the yellow streaks glowed!
We returned to regular light, where I very carefully cut open the highlighter crosswise using a sharp knife; any box cutter should work; just go slowly and carefully.
Inside will be a strip of fibers that contain the highlighter ink. This was so neat to see!
We added the fibers to our vase of water, where the highlighter color seeped down.
Travis very seriously added our flowers. Now we had to wait, but were rewarded with glowing flowers a few hours later!
