Many people have this childhood question: how exactly was the operation of beating the beer bottle head in the movie and TV series filmed? What exactly is the beer bottle made of, so realistic? And how do you break the window empty-handed? If

is not resolved, childhood questions will become middle-aged and elderly questions, so today I will answer your confusion.

In fact, the professional term for professional glass props is called breakaway glass, which was also called sugar glass in the past, because in the era without modern technology, the prop glass on the stage was really made of sugar.

But now, the prop glass is no longer made of sugar, but made of resin, or plastic. The common materials of

prop glass are polyurethane (a kind of plastic) and acrylic (plexiglass). Sponge is often made of polyurethane.

Look at the cola glass bottles on the left and right. Guess which one is real and which one is fake?

@Smooth-On

Actually, the one on the right is fake and the one on the left is real.

Smooth-On, a chemical company that has been making movie props since 1895, showed us that the process of making glass bottles for props that can be easily smashed is like this.

first uses the original glass bottle to make a mold.

can use cardboard to make a shell first. The reason for using cardboard is to cut it later.

then fix the original glass bottle with glue, then put on the cardboard box, and then fill the silicone rubber between the original and the cardboard box to make a mold. When placing

, ​​be careful not to leave fingerprints on the surface.

Pour the silicone rubber. When the

or other silicone rubber becomes hard, the whole mold can be cut open and the original glass bottle can be pulled out.

Seeing whether this process is inexplicably comfortable, it reminds me of using a spoon to dig jelly, and I want to cut it myself.

is then the step of modulating the resin color. This step is critical. Because the color largely determines whether the props look like the original. The working life of

resin is only 5 minutes, which means that the mold must be poured within 5 minutes, otherwise the material will be waste.

So, put the material in the vacuum chamber to remove the air, otherwise the glass bottle of the props will be full of bubbles.

Then pour the resin into the mold and make a few turns to spread the material evenly.

wait another 90 minutes, you can get out of the pot. The effect of

is like this-

finally sprays a layer of denatured ethanol or fire wine (2-propanol) on the surface to dissolve the resin surface and show a moist and juicy color.

wait another 24 hours for the resin to fully cure, and a glass bottle that can head without bursting will be born!

Actually, the thickness of this kind of prop glass will not exceed 0.33 cm, otherwise it may cause damage to the human body like real glass. The shape of

Plexiglas is even simpler. The effect is that it can be broken by blowing with the palm of the wind✋——

@New Rule special effects props

The so-called broken window is actually more when it falls on the ground. It hurts-

Of course, some props are thicker than glass, and they have special manufacturing methods. The

brick may be 3D printed with resin, but it feels like a sponge and is very light.

With these fake and real plastic props, Taekwondo level 10 is not a dream-

is very imposing even when drinking water-

can change from moving bricks to cutting-edge-

Of course, tables and stools are everything. They are not genuine products, they can let teammates send you assists and increase the effect of grabbing horses-

does not hurt at all, or the abdominal muscles are more painful-

Of course, if you want to take a picture of walking on the glass, you can Use soft silicone rubber instead of real glass.

is okay, a pinch can also play a role in decompressing oneself and blocking the opponent.

However,Some props are special glass. For example, the larger glass windows hit by cars are made of tempered glass. But they weren't really broken by a car or pierced by a person, but they were exploded with a pyrotechnic device before the collision between the car and the person.

So you see, smashing the head with a glass bottle in a TV series really tests the actors’ acting skills...because it’s really hard not to laugh. The following are a few unqualified demonstrations of the running tricks-

so that there is no pool bottle showdown to explain it. Because the "glass" slag may... float... rise... come...
