This was a great demonstration that I showed my sixth grade students. I had each class work cooperatively to construct one model per class. All five classes successfully constructed and practiced making longitudinal waves. The model helped them understand the transfer of energy through surface water waves. Thank you for the idea and a hands-on way to reinforce the concept.
are you gonna eat those?
@Silas Coleman nah i think there mine
@@TheRealDrGiggleTouch No they’re mine
(. _ .)
@@TheRealDrGiggleTouch they're probably expired by now :(
I eat babies
So amazing, i've been to waterparks before and i've surfed on one of those wave machine, but I never realized it is so easy to make at home. who would have thought it would be so easy
EXCELLENT MODEL. Ive been trying to ficgure out how to create an inexpensive version of the more "professional version/lab grade" for a while now. Shows nearly everything Id like to show about energy traveling through media:) You should make a vid to demo how to use it to show constructive and destructive intereference;)!
"Jelly babies"
That was very comforting for some reason
Cuanto mide de largo
I love these simple demonstrations that anyone can make.
I like your project it was awesome. I did it for a Science Fair and i got a A+. Thank you
This makes it very easy to see that each constituent piece of the medium undergoes simple harmonic motion normal to the axis of wave propagation
good demo
Absolutely super video. Thank you. I might do this at school for Science Week.
OH nice.... just a verified youtuber passing by in the comments
Great model and explanation, helps me a lot. Thanks!
Fantastic. Have to apply this in one of my classes.
WHat a beautiful and witty demonstration!
my class did it and loved it and they said it taisted good so if your looking for a wave lesson plan this is the way to go
Really the most elegant science demo ... Inspiring
Nobody:
My physics teacher knowing full well that its Ramadan: Today class, we’ll be watching jelly babies demonstrating a transverse wave!!!
lmao SAME
same
Jelly babies are haram anyway
Lol😂😂
I'm no Muslim in any way, but I understand the joke without googling
ANY one else had to watch this in online sience class
Yeah
Lmao yeah
Yurrr
Mee bro
ye
Thank You Sir for making this vedio. This helped me a lot to get marks easily and to know more about the WAVES....👍👍👍
Thank you so much for this awesome video you uploaded in.🙋🌹❤
Great video and demonstration, love it 💚
Great activity for Physics or Earth Science. You can also demonstrate longitudinal waves by tapping down on the end. Students will observe that longitudinal waves move faster than transverse waves, analogous to comparing P waves and S waves.
i love everything about this! :)
What a wonderful representation.....I wish you'd been my science teacher!
This is an awesome activity that makes wave movement visible. We can not use food in our classrooms so I am replacing the gummies with small pieces of clay. I'd like to hear what others are using instead of the candy.
I have the same issue - I am going to try next week using wooden clothes pegs (the kind with the spring in them). Then I can adjust their position quite easily. I was thinking pieces of clay might be difficult because you'd want them to be uniform mass. How did you get on?
This is an excellent demonstration to help students develop an intuition about waves and their propagation.
fantastic....congrats teacher!!!!
It's so great, thanks for this video. I Will try it
Pretty cool I love simple science experiments.
Very beutiful and brilliant! Congratulations!
Great! Thanks for the idea!
Congratulations, nice for visualise 👏👏
Thank you sir.. It really helps me for my module
Brilliant! Thanks for sharing
？B
Can you do a transverse and longitudinal wave with this?
it's brilliant!!! Thank you, Sir)
Really...amazing... I'm inspired
Awesome im off down the shops!
great work, helpful
Exceellent demo.
Great video - thanks:)
Hey we did that for our physics project too!!
So one of cool things for a more advanced discussion is: what happens at the bound between fast an slow waves? There has to be reflection, not just transmission.
This is really making me want jelly babies
You can make a mini version of this using regular scotch tape, toothpicks, and mini marshmallows :)
Greg Pasacrita I must do!!!
I want to do it for science experiment but I don't have mini marshmallows. Any substitue?
@@toxicflatulence9437 eraser pieces
@@tiredcat6653 thank you for the idea but I already did the demonstration and I used straws instead of toothpicks and the eraser/marshmallows
thnx man
Iam gonna try it
When you remove mass the speed of the wave increases, is there an impact upon the amplitude of the wave, or does the amplitude remain constant as it travels from the sticks with candy through the sticks with no candy?
This is Great!
I presume you've seen the black & white AT&T archive material that shows a guy using a similar setup.
I wonder if anyone noticed the reflection from the discontinuity you introduced.
love this!
Brilliant. Thanks
BRILLIANT!
Oh wow that is one beautiful creature!
amazing DIY machine
very creative
who else is here cuz Mr. Pauley wants us to make this for science class for some reason
Can somebody explain this in terms of energy? I guess energy is being conserved right?
I'm trying to figure out how to incorporate collecting data and putting math into this. I'm thinking of having stop watches for groups to see the different time of the waves, but I don't know how to do this. We've studied electricity, magnetism, light, sound, and are moving onto plate tectonics so I want to tie it neatly together. Any pointers?
please what the material you used
an awesome demonstration
Ji Vera level
Very clever and well done! Thanks! You might have even further benefits if you could lace the jelly babies with salt peter and a birth control substance! The students might then pay further attention! Best of luck mate!
How big could you make this?
Thanks for the video.
Ke what sticks?
How much stuff did you use
Great, Scientist in_built !!!!!
This is cool I wonder when I will learn this in school
I remember making this in school
can we use nothing other than gelly
Very clever.
Hello , I'm trying to help my daughter with a second grade science project. I feel like we found a great project idea just having a bit of an issue on how to keep it in a way that compliments her age group. What would be a good question to ask for a second grade science fair project using the gummy bear wave machine in regards to sound? What kind of graphs could my second grader make? I was thinking to measure how fast the wave comes back to the starting point when we add energy to the wave machine. Repeat this procedure 5 times taking 5 gummies off each time until i reach the mid point of the gummy wave machine. Thank you in advance😊
The Doctor would really love this
I wonder if after this quarantine this video will become some what popular because of the teachers
You know what I’m doing this exactly for my science final project 😭🤝
I want to make this into my science fair project. What do you think should be the essential question. Also, how can I make a smaller one?
Cristina Evans Maldonado question do waves travel at constant speeds per given medium
Helps a lot
Has anyone tried to replicate this? What types of problems did you run into? I imagine the kabob sticks wouldn't stick well and would move around a bit. Considering replicating it for a 6th grade class.
A very nice demonstration, but eating in the lab........
pklongutoobe lol
😂
will this work if you play music or have a frequency go through metal?
Nice!
genious!
Interesting. So it's really the candy that keeps the children's attention span locked onto the wave device. How else would they pay any attention to such unless it's a cell phone with a new and amazing app?
For how long it will keep this motion?
Is this machine wave considered transverse or longitudinal
How many sticks did you use? How long is it?
It was very good, the best I saw here on RUclips, congratulations. What is the distance between the toothpicks? Did you use glue to attach the toothpicks or put them directly on the tape?
Thank you.
The kebab skewers are about 5cm apart - the separation does affect wave speed by changing the mass per unit length, but in practice you don't have to be too accurate. We usually line them up by eye.
They're stuck directly onto the tape. Most people then put another layer of tape to sandwich the sticks, which also helps the apparatus last a bit longer, but it's not really necessary and it can change the behaviour of the tape as a torsion spring. So I never bother.
@@JonathanSanderson What type of tape is needed for this experiment?
@@markchesterdelacruz4542 In the UK we typically call it 'Gaffer tape', I don't know if that's common internationally. This stuff: en.wikipedia.org/wiki/Gaffer_tape. In practice most brands of wide cloth-ish tape work well, as does duct tape. Elephant and Duck brands are good, but so are many others. Some of the non-branded tapes aren't very sticky and would definitely benefit from a facing layer; it's one of those situations where it's probably worth buying the better tape in the first place.
One thing I've never tried is to splice from one brand/type/weight/width of tape to another, while keeping the stick pitch and sweet mass the same. With a bit of faffing about I suspect you could find combinations where the wave speed clearly changes with the medium.
Other commenters have noted that you can sometimes observe reflection at interfaces, eg. where you remove half the sticks. I haven't noticed anyone comment that if you send a pulse down a long tape you can observe wavepacket dispersion. I suspect you could even measure it, which might be fun.
In 30 years of demo wrangling, this is still the one of which I'm most proud!
how it weave.
that's really creative......
Will this method work in the water?? Feedbacks are appreciated.
Can I connect the end of the duct tape to a speaker to see the sound waves? I was wondering would that work?
Most soundwaves are quite a bit too fast to see. They are in the hundreds or thousands of Herz.
what a video sir ji
will this work if an earthquake occurs will it move ?
Good idea
I am such a nerd. I want to build one just for funzies now lol.
It's good to understand wave motion, but in nature what plays the role of the duct tape? In other words, what plays the role of the spinal chord of a wave?
Hi,
How does it demonstrate light waves? I'm really confused. Can anyone help?
shocked that this is still being watched even in 2021
very cool
sir what is the required material in this demonstration
I love you want to have your jelly babies. Thanks for sharing this is exactly what was looking for with a clear explanation
Cool!
Can anyone do EMW as it's combination of two waves i want two visualise it
OMG I'm in love
