Recently across social media there is a trend where students take random items they find at school or home and stick them to the wall without using any adhesive. The trend began with people taking their charging bricks and sticking them to the wall, as if it was magic.
Micro-Welding is a common technique used when bonding together items that are relatively small in size.
When used correctly, this creates the phenomenon going around on Snapchat and Twitter. Yet, there are a few requirements when it comes to successfully doing this project. “It only works on painted surfaces…if you were to do it on wood, it would not work,” said Argao. The reason behind this is because when you move the object at a fast enough rate, the paint will melt and that is the reason it creates an adhesive solution.
For a longer explanation, Gabriel Argao explains the process of micro-welding and the adhesion phenomenon.
This trend is remarkably universal, with people using whatever they find in their classrooms, or their electronics, to random items like brooms. Just remember behind every fun trend is some form of science.
Flinging turds at the wall was all my underfunded school could afford teaching us to experiment with…
Something that would also stick to the wall would be a card. something that could make a card stickier would be a bit of glue on the bottom and i stuck a card to a wall and it stayed on the wall for two seconds. (without glue)
The only way to achieve happiness is to cherish what you have and forget what you don’t have
