If the weather is too humid, the writing on the whiteboard will become illegible!

In humid weather, clothes don't dry easily, floors stay wet, and even whiteboard writing behaves oddly. You might have experienced this: after writing important meeting points on the whiteboard, you turn around briefly, and upon returning, find the handwriting has smeared or slid down, causing both amusement and frustration. There are interesting scientific principles behind this phenomenon.

What are the ingredients of whiteboard pen ink?

The reason why whiteboard marker writing begins to "let go" is mainly due to its inherent of being easily erased. Its ink contains substances that reduce adhesion - release agents. These release agents are usually some "oily" substances, such as liquid parin or esters. These release agents, along with other additives, are dissolved in solvents to form uniform ink. When Dry Erase Whiteboard Pen Ink is written on the surface, the solvent evaporates, these oily release agents can act as a barrier between the colored writing and the writing surface, preventing the writing from closely adhering to the surface Moreover, it is affected by the humidity of the air. Simply put, when the air has a high content of water vapor, the Whiteboard Marker Pen Ink writing on the whiteboard like being wiped with a layer of lubricating oil, making the writing unstable and prone to "slipping".

Why does the whiteboard pen ink still look intact after it slips off?

This is related to the film-forming resin in the Refill Whiteboard Marker Pen Ink. Generally, film-forming resin components such as polyvinyl alcohol butyral are added to the Whiteboard Marker Pen Ink, which not only helps the pigment to disperse evenly and adjusts the viscosity of the ink, but also forms a protective film the writing dries. When the whiteboard marker writing encounters water, we can clearly observe that this layer of film is completely washed away, and at this time, the writing is deformed and falls off, it can still maintain a complete structural form.

These components can help the pigment disperse evenly and have the function of adjusting viscosity of the ink, etc. After the writing dries, it can also form a layer of film. After adding water, we will see this layer of film washed away as a whole.

Do an interesting DIY experiment on whiteboard pen ink to verify!

Practice makes perfect, come and give it a try! Choose a dry weather, take a whiteboard pen, find a smooth surface, pour some water on it, and you can discover some interesting phenomena!

Tools and materials needed for the experiment

①Fast Dry Whiteboard Pen Ink (black is sufficient, other colors can also be added)

②Oil marker pen is required (other types of pens can be used to compare phenomena)

③Clean and smooth surface (ceramic plates are recommended, but aluminum foil, smooth tabletops, glass, etc. can also be tried)

Basic ways to use with whiteboard pen ink

①Draw patterns on porcelain plate with whiteboard pen.

②Let ink dry, then pour water into tray.

③Observe floating picture on water surface.

Advanced ways to use with whiteboard pen ink

①Use oil-based marker on porcelain plate for durable patterns.

②Use a whiteboard pen to draw washable patterns.

③After all the ink is completely dry, pour water into the tray.

④Create fun tricks with fixed and washable parts, like a person being sucked by a UFO.

How else can we play? It depends on your imagination! After the experiment is completed, remember to clean the plates with alcohol.
