Can You Hear Sound in Space?If space is a vacuum, is it possible to hear sound in it? Trace is here to discuss why sound travels differently in space.

What is a vacuum? Is it matter?

“A vacuum, to us, is a space with no matter in it. As a practical matter though, it's really a space with very little matter in it.”

Amazing Water & Sound Experiment #2Add me on Facebook. (click LIKE on Facebook to add me)
https://www.facebook.com/158773774166995
Ever since I created the first version of this video a year ago I've been wanting to try it again with more water and better lighting / footage. This is a really fun project and when you first see the results, chances are your jaw will drop. The main thing to keep in mind for this project is that you need a camera that shoots 24 fps.
The effect that you are seeing can't be seen with the naked eye. The effect only works through the camera. However, there is a version of the project you can do where the effect would be visible with the naked eye. For that project, you'd have to use a strobe light.
For this project you'll need:
A powered speaker
Water source
Soft rubber hose
Tone generating software
24 fps camera
Tape.
Run the rubber hose down past the speaker so that the hose touches the speaker. Leave about 1 or 2 inches of the hose hanging past the bottom of the speaker. Secure the hose to the speaker with tape or whatever works best for you. The goal is to make sure the hose is touching the actual speaker so that when the speaker produces sound (vibrates) it will vibrate the hose.
Set up your camera and switch it to 24 fps. The higher the shutter speed the better the results. But also keep in the mind that the higher your shutter speed, the more light you need. Run an audio cable from your computer to the speaker. Set your tone generating software to 24hz and hit play.Turn on the water. Now look through the camera and watch the magic begin. If you want the water to look like it's moving backward set the
frequency to 23hz. If you want to look like it's moving forward in slow motion set it to 25hz.
Have fun!
Singing wine glasses - Science with children - ExpeRimental #4Create a wine glass orchestra in your kitchen and explore how sound is caused by vibrations.
For more ideas, and to download an info sheet click here: https://www.facebook.com/Ri.ExpeRimental
Marieke and Tilly experiment with making music and doing science experiments at home. Using wine glasses filled with different volumes of liquids, they investigate how sounds are caused by vibrations and how changing the volume of liquid affects the pitch of the note. Simply rubbing your fingers around the rim of a glass can make an amazing noise. Explore sound, music and science in this fun activity to do with kids.
With enough glasses and little bit of practice you might be able to play 'Ode to Joy' like Marieke!
ExpeRimental, brought to you by the Royal Institution of Great Britain, is a series of free short films that make it fun, easy and cheap to do science at home with children aged 4 to 10. Our films give you lots of ideas for kids' activities that will help you explore the world around you, question and experiment together. We'll show you how to do the activity and how to make sure adults and children get the most out of it. Why not have a go and then tell us what you think on our Facebook page? https://www.facebook.com/Ri.ExpeRimental

Learn how to make a harmonica for a science project with the instructions in this Howcast video.
I love experiments that don't require, really, any materials. For this
experiment, it's amazing. Every time you go into the doctor, you could ask
your doctor, "Hey, Doc. Could I please borrow a tongue depressor?" All we
need is just tongue depressors and rubber bands, and I can show you how
amazing sound truly is, and how . . . again, we need a vibration, you need
something for the vibration and the air to travel through, and you need an
ear. I'm going to make an amazing instrument using nothing but tongue
depressors and rubber bands. You sound like a rapper, Rapper Carmello.
Step 1, is you take a rubber band. I think a thicker rubber band works
great for this experiment. I take this tongue depressor . . . if you wanted
to, actually, you can color your tongue depressors so that your harmonicas
look amazing. I'm just going to make mine non-colored, but if you wanted to
use markers, you can make them colored, make them look fun; could actually
look like you store-bought these. Step 1, is take your tongue depressor.
Large rubber band for this step. You can take it; very easily just wrap it
around your tongue depressor. Just like that. Easy step.
Step 2, again, card stock. I don't like typing paper, I don't like computer
paper; I like using card stock. It's a little thicker and makes the
experiment work that much better. I'm going to cut out a piece, 2 inches;
2" x 2". There's your math measurement. I take it, I'm just going to fold
it, fold it, and fold it. I'm going to take the square, and I'm going to
fold the square 3 times. I take a piece of tape that I'm just going to roll
around so that the tape is sticky on all of its sides. Take the piece that
I cut out, put it on the tape. I'm going to take my second tongue
depressor, not the one with the rubber band, and I'm just going to tape it,
not at the end, I'm going to leave a little bit of space just like that.
Now I'm going to do the same thing twice. I'm going to take another 2"
square, remember, 2" x 2" x 2"; I'm going to fold it, fold it twice, fold
it 3 times. It's exactly the same step. Take another piece of tape. Roll it
so that it's sticky on all of its sides. You're going to make this exact .
. . it's going to be symmetrical, it's going to look exactly the same,
you're just going to do it on the other end. Again, a little bit of space.
Now I have that; it looks like you're going snowboarding, but we're not.
I'm going to take what I did in Step 1 and Step 2, and I'm going to make a
stick sandwich here. I'm going to push it together. Now I'm going to take 2
smaller, thin rubber bands. It doesn't really matter, but I really think if
you had a thicker one, its fine, but these thinner ones really, really work
best. I'm going to make this really tight. Right over where the paper is,
I'm going to take the rubber band, I'm going to rub it around, maybe 6 or 7
times, just so that that end is really tight. 1-2-3-4-5-6-7. Again, you're
going to make it exactly the same on the other end. 1-2-3-4-5-6-7.
When you look at this, it doesn't look like much, right? The cool part is,
when you speak, the vibrations from your mouth hit the rubber band. The
air, all the vibrations are made; amazing sound is heard. The compressed
air creates these waves that travel through the air, hit your ear, and you
hear music. If you don't believe me, look. Check this out. Breathe in,
breathe out. You can even talk into it and make really cool sounds, like .
. . Make music. It's awesome, and you made a homemade harmonica using
nothing but tongue depressors and rubber bands. How cool is that?
