When you hear gunshots or falling sound effects in movies how do you think they are made? Does someone shoot a real gun or does someone really fall?

You’d be surprised to know that many of the sounds you hear in movies are not made from the source you think they come from. Matter of fact unless absolutely needed, all the sounds you hear in movies are created using everyday things. Rainfall is just bacon being cooked; the sound of a person falling is just a huge book being dropped on the floor.

1The sound of thunder

Thunder is a crucial sound effect in many movies. How is it recreated? By using aluminum sheets! You may have thought that the actual sound of thunder is captured but that is not the case. Shaking it and swinging it in front of a microphone can recreate the sound of thunder. More effects can be added to make it more authentic.

2Rain pattering

You may have thought that movies actually capture the sound of rain. Sometimes they do and sometimes they don’t. If they require heavy rainfall and it isn’t there, they recreate the sound using bacon. Sizzling bacon can recreate the sound of falling rain perfectly. Another technique used is pouring rice on a hard surface.

3Cracking eggs

While showing eggs being cracked for cooking, dry ice cream cones are used. Cracking the ice cream cone reproduces the sound of an eggshell being cracked. In many cases, eggs are cracked and creatures are shown to come out of it. In this case, artists wear gloves, slather liquid soap and squish a melon. This produces a wet sound.

4Crushing sounds

Any horror movie or action movie will inevitably have a scene where someone gets hurt. In case someone cracks a bone or someone crushes someone’s bone, the sound effect isn’t that hard to create. It doesn’t require hurting anyone. A stick of celery is that’s needed. Breaking a stick of celery creates a distinct crunch sound.

5Sound of a falling body

No actual person is thrown on the ground to achieve this sound. The slump sound is actually recreated using big books. Big heavy books are thrown on the ground to create this sound effect. In some scenes, the sound of a person falling is heard but the person is not shown. This is where those sounds are used.
