Safe for Most KidsReviewed June 2026

This episode is safe for most kids and offers a fantastic, hands-on introduction to the science of sound and vibration. It excels at explaining complex concepts like resonance, frequency, and pressure through fun, real-world experiments, but parents should note that some demonstrations (like breaking a wine glass with sound or using a powerful subwoofer) are clearly labeled as 'do not try at home' and are presented as professional demonstrations.

What Parents Need to Know

This video is a highly engaging and educational resource that teaches children about the physics of sound, vibration, and pressure. It does an excellent job of breaking down abstract concepts into visible, understandable experiments, such as making salt dance on a drum, using a giant megaphone, and creating a vibrating robot. The host, Phil, is enthusiastic and clear, and all potentially dangerous experiments (like shattering a wine glass with sound or using a high-powered subwoofer) are explicitly shown with safety warnings and are performed by experts. The only minor concern is that some experiments involve equipment (like lasers or liquid nitrogen) that could be misinterpreted as safe to try at home, so parental guidance is needed to reinforce the 'do not try this at home' message.

Talk to Your Kids About

  1. 1After watching, can you explain in your own words what a 'resonance chamber' is and why putting a phone in a glass makes the music louder?
  2. 2Why do you think the giant megaphone made the sound louder, but only when it was pointed at you?
  3. 3The video showed how a wine glass can break when it hears its own special note. What does that teach us about how sound can be a form of energy?
  4. 4What was your favorite experiment in the video, and what did it teach you about how sound or vibration works?

What's This Video About?

We all know sound is extremely important to our lives but what is it made up of?! Join Phil as he resonates at different frequencies to learn just exactly how sound, vibration, and air pressure work together in our world. #ScienceMax #Sound #Vibration If you want more make sure to subscribe! ▶ https://www.youtube.com/@ScienceMax?sub_confirmation=1 Have you ever done a science experiment and wondered “What would this be like if it were HUGE?” Welcome to Science Max, the exciting series that turbocharges all the science experiments you’ve done at home. 0:00 - Loudest Sound - Phil tries to bend the power of sound to his will by making the loudest sound he can. Plus: make cornstarch mud dance, shatter a wine glass, and make patterns with sand – all with the power of sound! 20:06 - Vibrobot - Vibration is the idea behind a shaky vibrobot – one maxed out enough so Phil can ride it! Plus: spinning an 8-foot coin, suspending water in mid-air, and lasers! 40:13 - Air Pressure - Learn how to use air pressure to make your own, home-made rocket out of a plastic water bottle. Phil maxes this out by using stronger bottles and even over-pressurizing them and finally by building a giant rocket out of plastic bottles. Plus, we blow up a bottle with liquid nitrogen and crush a steel drum using nothing but the air pressure around us every day.

Frequently Asked Questions

What age is this video appropriate for?

This video is recommended for children ages 6 and up. The concepts are explained in a clear, visual way that younger children can grasp, but some of the more complex physics ideas (like frequency and resonance) are better suited for kids who are already curious about how things work. The experiments are engaging and safe to watch, but the 'do not try at home' warnings should be respected.

Are any of the experiments in this video dangerous for kids to try at home?

Yes, several experiments are explicitly marked as 'do not try at home' and should not be replicated. These include breaking a wine glass with sound, using a powerful subwoofer to make cornstarch mud dance, and using liquid nitrogen to create pressure. The host and his expert guests always wear safety gear and give clear warnings, so the video is safe to watch but not a guide for unsupervised home experiments.

What will my child learn from watching this video?

Your child will learn the fundamental principles of sound and vibration, including how sound travels as a wave, what resonance and frequency mean, and how pressure can be used to power a rocket. The video uses memorable, hands-on demonstrations like a vibrating salt drum, a giant megaphone, and a self-destructing robot to make these concepts stick. It also teaches the importance of safety when doing science.

Is there any product placement or advertising in this video?

No, there is no hidden advertising or product placement. The video features a segment from the Ontario Science Center and a guest from Logic's Academy, but these are presented as educational partnerships, not commercial endorsements. All materials used (like plastic cups, markers, and bottles) are common household items.

Does the video contain any scary or upsetting moments for young children?

No, the video is designed to be fun and educational. While there is a moment where a wine glass shatters and a steel drum gets crushed, these are shown in a controlled, scientific context with clear explanations. The host's enthusiastic and playful tone keeps the content lighthearted, and the 'science' label on the screen helps reinforce that these are demonstrations, not accidents.

How can I use this video to start a conversation about science with my child?

This video is perfect for sparking curiosity. After watching, ask your child to explain their favorite experiment or to describe what 'vibration' means. You can also try the simple, safe experiments at home, like making a megaphone from paper or using a bowl and plastic wrap to see sound vibrations. The video's clear explanations make it a great springboard for discussing how science is part of everyday life.
