Welcome to a world where we make the invisible visible! Today, we’re diving into some amazing experiments, like floating magnets and creating a fire tornado using the power of wind. Get ready for some “Satisfying Science” with me, Nick Uas. As a scientist, I love discovering cool experiments that can make our everyday lives better. But remember, don’t try these experiments at home!
Have you ever heard the saying “seeing is believing”? While that’s true for many things, there are some phenomena we believe in even if we can’t see them, like viruses. Our world is full of invisible forces and energy waves, such as sound waves, magnetism, and gravity. In this episode, we’ll explore some of these invisible wonders, starting with something called resonance.
Back in November 1940, a bridge in Washington called the Tacoma Narrows Bridge collapsed because of the wind. The wind was blowing at 42 mph, which was strong enough to break small branches. But it also caused the bridge to shake so much that it eventually fell apart. This happened because of a phenomenon called resonance.
Resonance is when an object vibrates a lot because of an outside force. Every object has a natural frequency, which is the rate at which it likes to vibrate. If an outside force matches this frequency, it can cause the object to shake a lot. It’s like pushing a swing at just the right time to make it go higher. In the case of the Tacoma Bridge, the wind matched the bridge’s natural frequency, causing it to shake violently until it collapsed.
Did you know that everything, even humans, has a resonant frequency? For humans, it’s about 10 Hz. While being exposed to this frequency for a short time isn’t harmful, being exposed for a long time could potentially cause damage to our cells.
Next, let’s look at a fun experiment called the spouting bowl. This uses something called slip-stick friction. By rubbing our palms on brass handles while they’re wet, we can create vibrations that make the water in the bowl do some pretty cool things!
Now, let’s talk about magnetism with my engineering friend Maynard. A compass is basically a magnet that lines up with the Earth’s magnetic poles. We’ll show you how to make a simple compass using a magnet, a piece of cork, and some water.
Moving on, we’ll explore quantum locking with my friend Cat, an electrical engineer. We’ll use a superconductor called YBCO. When it’s cooled to really low temperatures, it can repel magnetic fields and make things float!
Finally, we’ll look at the power of wind again by creating a fire tornado. Using isopropyl alcohol and a safe setup, we’ll show you how wind can create swirling fire vortices.
Thanks for joining us on this journey through the invisible forces that shape our world. Stay tuned for more exciting experiments in future episodes of “Satisfying Science.”
Discover the power of resonance by using a tuning fork and a bowl of water. Strike the tuning fork and gently touch the surface of the water. Watch as the vibrations create ripples, demonstrating how resonance can affect objects. Think about how this relates to the Tacoma Narrows Bridge collapse.
Learn about magnetism by creating a simple compass. Use a needle, a magnet, a piece of cork, and a bowl of water. Magnetize the needle by rubbing it with the magnet, then float it on the cork in the water. Observe how it aligns with the Earth’s magnetic field, just like a real compass!
Create a simple guitar using a box and rubber bands. Pluck the bands to produce sound waves. Experiment with different tensions and lengths to see how they affect the pitch and volume. This activity will help you understand how sound waves, another invisible force, work.
Experience slip-stick friction by trying the spouting bowl experiment. Fill a bowl with water and rub the handles with wet hands. Observe how the vibrations cause the water to spout, and think about how this relates to resonance and vibration in everyday objects.
Watch a video demonstration of quantum locking and levitation. Discuss with your classmates how superconductors work and why they can make objects float. Consider the potential applications of this technology in the future.

**Today, join us as we explore the concept of making the invisible visible. We will delve into fascinating experiments, from levitating magnets to harnessing the power of wind to create a fire tornado.**
**Welcome to “Satisfying Science.” I am Nick Uas, and as a scientist, my mission is to discover the most intriguing experiments that can enhance our everyday lives. With the help of expert friends, we will uncover the secrets of the universe through exciting demonstrations. Please remember, do not attempt these experiments at home.**
**Have you ever heard the phrase “seeing is believing”? While I appreciate the sentiment, I believe in phenomena even when they are not visible, such as viruses. Our world is filled with energy waves and forces that we cannot see, including sound waves, magnetism, and gravity. In this episode, we will examine some of these invisible phenomena, starting with resonance.**
**In November 1940, the Tacoma Narrows Bridge in Washington collapsed due to wind. The 42 mph winds were strong enough to snap small branches, yet they caused the bridge to fail. The bridge was designed to be flexible, but instead of dissipating the vibrations, it amplified them until it reached a breaking point. This disaster serves as a prime example of resonance.**
**Now, let’s discuss resonant frequencies with my friend Cole, a chemistry expert. Resonant frequencies refer to how an object vibrates under an external force. Each object has a natural frequency at which it prefers to vibrate. When an external force matches this frequency, it can lead to significant oscillations.**
**For example, consider pushing a swing. If you push at the right moment, you can increase its height. Similarly, in the case of the Tacoma Bridge, the wind matched the bridge’s resonant frequency, causing it to oscillate violently until it collapsed.**
**Interestingly, all matter has a resonant frequency, including humans, which is approximately 10 Hz. While exposure to this frequency wouldn’t cause immediate harm, prolonged exposure could potentially lead to cellular damage.**
**Next, we will demonstrate a phenomenon called a spouting bowl, which utilizes slip-stick friction. By rubbing our palms on brass handles while dipping them in water, we can create vibrations that resonate throughout the bowl. This will cause the water to exhibit interesting behaviors.**
**As we continue, we will explore magnetism and compasses with my engineering friend Maynard. A compass is essentially a magnet that aligns itself with the Earth’s magnetic poles. We will demonstrate how to create a simple compass using a magnet, cork, and water.**
**Moving on, we will explore the concept of quantum locking with my friend Cat, an electrical engineer. We will use a superconductor known as YBCO, which, when cooled to extremely low temperatures, can repel magnetic fields and create levitation effects.**
**Finally, we will return to the topic of wind and its powerful effects. We will create a fire tornado to illustrate how wind can generate cyclonic activity. Using isopropyl alcohol and a controlled environment, we will demonstrate the principles behind fire vortices.**
**Thank you for joining us on this journey through the invisible forces that shape our world. Stay tuned for more exciting experiments in future episodes of “Satisfying Science.”**
