Science magic: paper that can't be cut off
Science magic: paper that can't be cut off
No matter how you cut it, it's all connected.

A piece of paper is folded in half, cut out a paragraph, and it is still connected after it is unfolded. Cut again, the note can still be linked together.

this is a trick that is sometimes classified as a scientific experiment, but I don't think there is much to say about science.

the key to continuous cutting lies in the back of the note: it is treated with glue and then sprinkled with a thin layer of talcum powder (talcum powder) to prevent adhesion during folding. When scissors cut paper, the two layers of glue are pressed closely together in the part of the incision, so that the molecules in the glue are bonded together by intermolecular force, sticking the note at the break.

most of the English experiments I saw used rubber glue (rubber cement), an adhesive made by dissolving rubber in an organic solvent, but it was not easy to buy. According to the Science Game Lab, Polaroid gum can also achieve this effect.

as for the glue I used in the video, it is the one in the following picture:

I don't know exactly what the glue should be called, but the composition is also a polymer dissolved in an organic solvent.

in the choice of notes, most versions use newspapers, and I use a color-printed advertising leaflet, and the effect is no problem at all. The only thing that makes people feel pierced is that the cut piece of paper is always easy to stick to the scissors.
