One morning in school, you step inside the classroom, and the walls at the back seem to be performing a magic trick. A ballpen clings to the wall. A dustpan hangs as if suspended by an invisible force. Your classmates gather around, laughing as they slide objects across the wall, amazed as though they had switched gravity off.
Across TikTok and all over social media, millions have tried the same trick. Pens, rulers, markers, even brooms and chairsโgliding and holding in place. Who would have thought a chair with a heavy weight could cling to a wall? It may look like sorcery, but our curiosity lingers: ๐ธ๐ฉ๐บ ๐ฅ๐ฐ ๐ต๐ฉ๐ฆ๐ด๐ฆ ๐ฐ๐ฃ๐ซ๐ฆ๐ค๐ต๐ด ๐ด๐ต๐ช๐ค๐ฌ ๐ญ๐ช๐ฌ๐ฆ ๐ด๐ฐ๐ฎ๐ฆ ๐ฌ๐ช๐ฏ๐ฅ ๐ฐ๐ง ๐ข ๐ฅ๐ฆ๐ง๐บ๐ช๐ฏ๐จ ๐ฎ๐ข๐จ๐ช๐ค ๐ต๐ณ๐ช๐ค๐ฌ?
Turns out, the โ๐ณ๐ฟ๐ถ๐ฐ๐๐ถ๐ผ๐ป ๐๐ฎ๐น๐น ๐๐ฟ๐ถ๐ฐ๐ธโ isnโt magic at all. Suddenly, you remember that behind every fun trend is some form of science. To make an object stick, you slide it against a painted wall with the right angle and downward pressure. This seemingly magic trick involves physics, hiding in plain sight when it appeared as that. A simple interplay of friction and normal force, the resistance that occurs when two surfaces rub against one another.
An article from The Mycenaean found that friction under the right conditions can become strong enough to counteract gravity. Paint, especially older or matte finishes, isnโt as solid as it seems. As the object slides, the rubbing generates a subtle warmth to make the surface momentarily pliable, as if it awakens a hidden stickiness. In those brief moments, the wall itself seems to cradle the object, while static friction quietly keeps pens and other objects from sliding back down.
According to the American Physical Society (APS), friction increases when pressure and surface contact riseโexactly what happens when students press and slide those objects against the wall. This explains why some walls seem stickier than others and why objects cling best right after sliding but fall off when slightly disturbed. The trick only works when:
โข The wall is painted, giving enough micro-texture for friction and grip.
โข The surface is flat, allowing full contact between the object and the wall.
โข Angle and pressure are correct, sliding downward while pressing increases normal force and friction.
โข The objectโs material cooperates, since rougher or softer surfaces cling better than smoother ones.
But while the trend appears harmless, the wall often takes the damage. Repeated sliding leaves greasy streaks from dirt and oils. Older paint can peel when softened by friction. Small scratches form where objects dig into the paint. And debris from graphite, plastic, or wood can lodge in these scratches, leaving permanent marks on the surface.
Under the Philippine Revised Penal Code (RPC), willfully damaging or defacing school property, including walls, may be punished as malicious mischief or vandalism. While these do not explicitly mention the friction wall trick or paint peeling, such acts could qualify if the damage is visible. In practice, minor damage like this is rarely cited, but it still serves us a reminder to only try with caution and be responsible when hopping on the trend.
Behind the laughter and the so-called magic wall trick, physics is simply behind the trick. When you see a pen, broom, or dustpan cling to the wall like it has mastered gravity, remember: no magic was performedโonly science. And while the thrill of the trick is fun, the wall pays the price every time an object slides against it. Try the trick if you must, but try responsibly, knowing that every playful push leaves a mark.
