thank you acellus!
who discovered the ultraviolet light?
I loved this weeks vidio it was so funny. Why was r.51 in such a hurry.
I don’t really like spiders, but the water spider was neat!
This was an awesome video!
This was an awesome topic!
cool, i was wondering is ultraviolet is colder than violet?
such a cool live!!!!!
this was such a cool video! see you all next week!
I thought the water spiders were interesting
Spiders can be fascinating but they still freak me out.
the fact how that metal can have holes drilled into it and still float without any water in it at all is really cool, and Im so sorry Im late and I loved this science live today
I love science live. I’m still crazy for the protégés! Thanks for all you do!
I love spiders and one day I want to become a Biologist and learn more thing about different animals.
THANK YOU FOR THE NEW BLOCK ON ACD2 🙂 🙂 🙂 🙂 🙂 🙂 🙂 🙂 🙂 🙂 🙂 🙂 🙂
The water spider was cool.
It was amazing how the super hydrophobic didnt sink
This was a cool live.
Wow that so cool spider live in water i didn’t know that.
Attending from Qatar, Doha!
This Ep was awesome and it was cool to learn about the Binary Decade Counter.
Spiders are freaking awesome! Love that they can be smart enough to use a bubble for air.
Hello from Idaho!
You’re the best Science Live
Science live was really fun.
So interesting how I learn something new every time I watch science live!
Water spiders have inspired some incredible technology!
This was so fun to learn!
This is so cool to know!
loved this science live! cant wait for next week.
Hello from South Dakota!
I love the science videos. Always learning new things.
The heat in colors really fascinates me, AC-D2 Has some moves 🕺
that is so cool! I love science live!!
Nice science live, and I had a thought for how to get the hydrophobic effect to work on a solar panel. Because I’m guessing we can’t put the marks in the panel directly, we put a clear plastic or other clear material over the solar panel with the marks put in so it creates the hydrophobic effect without damaging said panel.
Hello from Texas 😁
I love science live because i love learning about all the cool thigs the teachers talk about.
the hydrophobic aluminum is really neat I cant wait to see the applications for this
The spider was amazing! love it!
Water Spiders are so cool
My favorite part of the episode is the Technology Spotlight! In the Technology Spotlight, Dr. John discussed water spiders and the new material they made based on them. Aquaphobic material is a thin substance that forms a thin layer of air between the water. I believe that this could be used on electronic devices to avoid potential water damage. I can’t wait for the next update!
How many incisions or lines did the laser have to do for the pipe to float?
Is making surfaces hydrophobic similar to how Rainex works on car windshields? Could this property be used to help with the rain and fog on airplane windows?
I love water spiders, they’re such cool little dudes! It’s nice to hear them mentioned on this science live. 🕷️❤️
R51 is so funny haha
This might be the best Science Live this year so far!
It was so cool how the super hydrophobic did not sink I learned a lot today
The water spider was very interesting.
Same I learned so much too!
I love how it describes the suns colors even if we can only see one.
My favorite part was the music, I really like music, i think this episode is really cool
This video was great! The topic on water spiders caught my eye the most.
I’m so amazed by all this work and it’s all so inspiring and interesting to learn about.
My favorite part was watching ACD2 dancing to the music.
I wish I had a robot like that! This was an interesting lesson
So do I!
Binary Decade Counter is cool!!!
I didn’t know metal can float that well cazy!
That was so cool learning about water spider!
this was so cool!
Haha ACD2 dancing lol he got some moves
i love these lives! they are always so interesting! the spider was my favorite!
My favorite part was watching ACD2 dancing to the music!!
Its cool that the water spider lives under water!
Congratulations to Kelsey! I’m excited to see one of my peers excel. I look forward to seeing her film.
I love learning from this episode!
Same! They should add it to the AC-D2 songs in the activities.
This was so cool!
I loved learning about how different temps have different colors to them.
Loved learning the differences
This was a super cool episode!
I did not know thats how ultra-violet was explored
I like how they make it fun
I did not know thats how ultra-violet was explored it’s cool
i didnt even know water spiders were a thing sooo cool
Acellus is cool!
If the sun is different colors then why do we only see one color?
Yes I would love to hear a science life about this
The sun is actually white but the reason why the sun is yellow is because of something called Rayleigh scattering
The spider was soooo cool
they should make a scuba mask like how the spider does!
A prism held to the light can break down the colors of the sun
This was great! I love spiders and it was cool to learn about light splitting!
I loved the spider, it was super cool.
I loved the spider, it was so cool
how did they make technology that replicates the spiders properties.
I always learn so much from these videos!
it traps the air it the groves like if you drop a Lego in water it will have water in the holes
it will stay traped untill you take it out of the water.
loved the water spider, look forward to this every Wednesday!
What an amazing discussion on binary circuits and decade counters.
This episode was so inspiring; I loved listening to Dr. John talk about the idea of using the ocean’s waves power, that is so interesting! Never knew the water spider actually collected bubbles, and lived under the water, so amazing.
That water spider is pretty interesting.
I can’t wait next Wednesday! This was so cool!
You should have an ap theater class!
I thought that the water spiders were really cool and interesting. I also thought that it was cool that the aluminum was able to float. I don’t know if it would work or not but they should make it where your phone floats ,for if you drop it in water.
I find it so interesting how different temperatures of light have different colors!
water spiders are super cool!
That water spider was so cool!!
spiders are always so cool to learn about.
I love science live I always learn something new and it’s very exciting.
had a lot of fun watching science live it was really cool to learn about the water spiders
I always enjoy the science videos!
I really enjoyed the part the part about the binary code and how you could do it and i thought it was very interesting how it works
Since a decade counter is also called a mod 10 counter, what are the ten numbers it counts through before resetting?
The water spider was so cool to learn about!
I liked the discussion and the spiders!!
The water spiders was cool!
AI music is super cool!
The water spider is very interesting, the fact that it has to use air water bubbles to breathe when its not underwater.
Then noise from the frequency hear my ears. and the aluminum part was cool.
I have been doing acellus for a few weeks now and I love it I learn so much each day.
This was a really cool video about water spiders!
The dancing robot is cool!
hello from Florida
I love this video
I love watching the live!
that tiny robot was so cute! 🙂
thats so cool that the red side is hotter than blue and that blue fire is hotter than red fire.
love it!!!!!
The water spider is cool
The underwater breathing spider actually doesn’t breath underwater. The spider takes oxygen underwater and uses it like a diving bell. Humans use that same technology with scuba gear.
A decade is a long time!
My favorite part this week was the 3D printed robot that can sing and dance.
science live always teaches me new and cool things!
i love science lives yay!! hi from texas!
I loved learning about water spiders they are so cute! Have a great day!
I loved learning about the water spider and as always the new show to science live was great.
I love science also what time is it
Can we learn more about spiders?
Spiders and circuits are a cool learning combination!
I liked the hydrophobic metal
Learning about that spider was so cool!
I am inspired now to write my own book and animate it!
Researchers at the University of Osaka in Japan have been trying to tackle the problem of harnessing energy from waves in the ocean. This would be a great resource for fuel, as waves are always crashing on the beach. But, people have been trying for years and still no luck. The researchers, however, figured out this problem by having a gyroscopic system floating in the water that takes the energy from the waves coming into it while it spins.
AWESOME VIDEO!!!!!!! That was amazing!!!!!!!!!
That’s so cool that the spider brings air bubbles down and can store them in their web/carry it on their legs.
I wonder if they could put a hydrophobic application on cars so if one was accidentally driven into a lake or fell if that would help save people.
Circuits are super easy to make they just need so much energy which i thought was cool. R51 was so funny!!
I always enjoy your videos
The hydrophobic metal was cool
I loved this science live and I really want to see how to build a circuit that can divide by 3,7 and all the other numbers.
the R51 is so cool and funny!!
Is the Acellus Teacher Serum for sale?
It’s cool to learn about water spiders and light, looking forward to next live!
a new adventnier that’s so cool I can’t wait to see what she has to say aboute it so excited
It was cool learning about infrared light.
I love film! Perked up when it was mentioned in the beginning!
I loved this one i learned so much!
I love science live!!
I want to experiment with mirrors now.
I also really like how water spiders live mostly under water
I loved this science live cause i got to learn about the water spider which i didn’t know there was a water spider ~Abi
I loved this science live I like how water spiders glide across the water
Loved learning about the water spider! How cool that a spider can swim under water and blow bubbles to breathe.
loved this makes me wonder if i can make a clock
I have seen water spiders before.
Water spiders.. learned something new. Always a great show
The spider looked so cool.
love to learn about rainbows!
I loved this science live video so much!
Hi from Illinois! Another great Science Live!! The water spiders are so interesting I would like to see how they eat.
I never really liked spiders but learning about water spiders was intriguing to me.
the potoges are soo funny
It was interesting learning about how each color of light has its own temperature
science + live = awesome
In binary code, the number 9 is written as 1001, what happens to the counters display immediately after it his this number?
The web is really cool with the spider I did not know that spiders could so that
The water spiders were really cool and what they did with the aluminum I thought was very interesting.
It’s cool that the water spider can suction water to its body.
I never heard or saw a water spider, so this live really taught me something new today. I was very compelled the whole entire time. I can’t wait for what’s to come for the next live.
This was really cool and i learned a lot. I loved it!
Here from Texas, these videos are so interesting to watch!
very cool episode, i loved the spider!
R51 is cool!
Water spider are so neat!!!
I really enjoyed learning about impulses, outputs and flipflops.
I want to be an engineer.
The jokes at the beginning of the science lives always crack me up! lol!
science live time again yay.
Hii from Maryland
I ❤️Science Live!!!!
Wow!! Thats kind of scary knowing theres dry spiders hanging out in the water, but the hydrophobic properties are really cool!!
I loved the water spiders! They looked so cool, I really enjoyed learning about them! Thank yall for teaching us about so many interesting things!
A hydrophobic boat or drone sounds so cool.
Great live, the spider was pretty interesting.
Hello everyone, from jordynn
I really like how mirrors can reflect the colors of the rainbow.
This was so interesting and fun to watch i loved this.
Water spiders are so much cooler than i thought.
Wow I didn’t know different colors had different temperatures
I liked all the topics on this science live especially the water spider!
I learn so much from these science lives!
Water Spiders and Binary Decade counters! This was so interesting.
Why do different lights have different temperatures
This science live was very cool and interesting! Can’t wait for the next video live.
I loved this live thank you!!
loved “the protégés” as always! the water spider was very cool to learn about, thank you for science love!
That dance robot is so cute!!!!!
How do things become hyrofobic
This was a great Science Live. I really enjoyed it.
Thank you so much for the video. I like the spiders!
I never thought that electronics could do this, it’s very cool to watch!
Thanks for teaching us more about technology.
Wow! These new hydrophobic materials could do almost anything. The thought of unsinkable ships and buildings that can be protected from rain and storms sounds almost too good to be true! I really hope even more technological advances happen this year!
I enjoy these videos so much 💗
Your Science live is always so interesting!!!
What if you use a giant water wheel to capture the energy from waves?
What was the date that you started the social emotional classes?
I loved your science live! it was cool to see the inventions you made
i love the dancing robot
