Bought this to show the kids cool stuff. Now I'm obsessed with seeing what is reactive!
I had a great time with my partner unboxing the ultraviolet box and trying all the different components out! He really loved the pen, I have a feeling he may have left secret messages throughout the house even. This will be an adventure 🤣
