Floating Whiteboard Ink

Description:
I learned about this phenomenon when a teacher spilled their water on my whiteboard.  Make sure you are using a plate with an impermeable surface.  It's a great phenomenon for intermolecular forces.  Surface chemistry, temperature, color, ink type, polarity, salinity, and many more factors affect this phenomenon.
