🛑 Stop being hit by the curry vendor. Decode the Durian knock physics.
Today, the science mate has a tip for the "science boy"! We will decipher the Durian seller's secret. Just using the physics principle of "Resonance," you can immediately know which is soft and which is raw!
Do you know why the sounds of 'paste' and 'puff' are different? The secret is purely "inner structure"! 🤫
Raw Durian 🍈: The meat is still hard and clings to the shell, there is no space for air to penetrate. When we knock, the sound waves vibrate quickly, causing a high frequency, the sound that goes into our ears, so it comes out in a ton of solid pieces like "paste."
🤤 Durian Ripe: When the meat starts to ripen softly, the Durian meat shrinks a little bit, creating an "air gap" between the meat and the shell! Now, when we knock, this air gap acts like a larynx, a resonance, a decrease in the frequency of the sound, a greater wavelength, so the sound that is heard becomes a reverberation of "puff"!
This is a trick that can be described purely by science. Save this photo and post. Keep it open for viewing on the Durian panel. This summer, the science mate warrants the exact texture, the outer frame is soft in, definitely not curried! 💛✨
