Invisible ink.
Secretive and mysterious, the indispensable weapon of any self-respecting spy or secret agent.
As children, we were amazed when friends brought the "invisible ink pen" to school, leaving hidden messages all over our notepads and papers that only showed up under ultraviolet light.
A North Carolina-based artist and Youtuber, Peter Draws, has taken the invisible ink game up a notch to produce a stunning illustration on an empty notebook page.
With a glass dip pen and invisible fountain pen ink that glows under black light, the elaborateness of Peter's drawing and the attention spent on each detail is mesmerising to watch as it takes shape under his pen.
