R51 is the best part of science live
I liked the comparison between ultraviolet and infrared.
I loved this live science it was very funny and cool but I love the robot more 😊
I have a fear of spiders but the water spider is definitely cool.
This was a very cool science live!!
These are fun.
Inferred things are interesting and how its works
What exactly did the laser do that made the tubes hydrophobic?
This episode was interesting and easy to follow.
Was the man who invented ultra-red inspired or wanted to use ultra-red light or did he just want to prove its existence?
At first I seen decade counter and I was confused but he did a good job at explaining and it really made sense
Loved the learning about the water spider that was pretty cool!
I love learning with Accellus.
Do you think other animals could evolve to live in the water?
I loved this science live it was really interesting to watch
this episode was fun! :))
that breakthrough that makes metal immune to water what if you make robots that can go in to water and not worry about the circuits geting wet.
I thought this weeks episode of Science Live was astonishing. My favorite part was the technology spotlight with Dr. John. I never knew that water spider even exists, and it using such a amazing technique with their webs is amazing. The way engineer’s are trying to apply hydrophobic tendencies to something like metal. Using this new discovery for ship building sounds extremely interesting, and they could also apply this technique for planes so that when they crash perhaps they could floating above water giving the everyone extra time to be rescued. I loved today’s episode and I can’t wait to see you and the rest of the team next week Mr. B!
I never heard of a binary decade counter.
Today’s science live was fun!
That’s so interesting! awesome video!
why was acellus created?
The part about the underwater spider was interesting
Thank you! I didn’t know there was a such thing as a water spider. That’s so cool! 🙂
Science live is the best! Spiders are so cool.
Love the video! Love learn about spiders!
Very interesting! Crazy how people can make sinking objects and make them float. The water spider was interesting too.
Those water spiders are so cool
interseting water spider never heard of that till now
The little robot was absolutely adorable!!!
That is cool that they can make metal float.
I have a 3-D printer and it is a lot of fun.
The spider and the photos were really cool. I dont like spiders
I learned so much today I can’t wait for next weeks episode
Infrared is so cool! Maybe you should have invaded or thermal phone camera attachments on the accelus store.
I liked the water spiderrrr
science live is so fun!!
wow great science live I loves it!
this was so cool! So much fun to watch!
r 51 you know why teachers are so smart because they learn that is why they are so smart
Hydrophobic surfaces is fascinating, and i love how they got the idea from observing a spider.
Awesome video today, really enjoyed it!
That’s a cool robot!
I love science live! It was so cool to learn new stuff.
can’t wait for next one.
it’s super fun learning about coding
This is an awesome live
Hello from Texas, loved learning about the circuits.
Hi i am from South Africa and I am in Florida now I live in North America. Yall like country music.
how can the gyroscope measure waves is it infared or motion senssor
I don’t know how I feel about water spiders haha
I found it cool how the water spider can actually swim.
This was a great science live
I loved this video with spiders, circuits, and light splitting. I learned so much
Hello from texas!!!
that breakthrough that makes metal immune to water so what if you make a robots that circuits do not get wet like if there is a flood robots would be able to go out in the rain and water plus still work.
i love science live and learning
Very intertaining live this week!!!!
I enjoyed learning about water spiders and light splitting. I am looking forward to Acellus World. I am glad that you can attend online. I learned a lot watching the Science Live this week.
what happens when you mix hydrogen and carbon dioxide
learning about the water spider was so interesting!
Awesome lesson about the water spider!
Water spiders creep me out, but still cool!
Suprising how circuts are easy to make
This weeks live was so cool can’t wait tell the next one!
l loved the rainbow
when does the binary decade counter know when to add 1
The Social emotional part was funny.
Loved Breakthrough Moments in Science with Dr. Tobias.
That special aluminum tube is just a piece of magic. That is incredible.
Water spiders are cool.😀
I’ve always really liked the social emotional learning courses
I like water spiders.
Hi, from Alaska!
I took a coding course here on Acellus but didn’t have a physical robot to watch dance, so it’s cool to see that!
HELLOOO! I enjoyed this live! I’m excited for the next live!
i love spiders so much!! water spiders so interesting to me!
Hopefully, the water gyroscope is a success
Thank you for talking about the water spider, they are so cool to me!
the water spider is super cool!
Hello! I’m Olivia from CT!
I loved this science live! It was so cool to learn about the water spider
What other kinds of invisible light are there other than infared?
The Protojètès are so cool! r-51 was amazing! Good job Claudia! I love spiders! Thank you!
How many numbered circuits are there?
Science Live is awesome!
the water spider was cool
Thank you so much for the educational lesson on infrared light. this video was very enjoyable!
I really liked the part about the water spider; I was actually drawing a spider when that part started playing!
Loved the story on how we discovered infrared light. How cool!
I’m so excited for the science fair!
I loved learning about circuits!
I don’t like spiders, but the water spider is really cool.
So happy to hear you talk about water spiders! They’re so fascinating!
I can’t wait to see the big robot!
I really like Dr. John’s section on water spiders.
I learned that a binary decade counter counts from 0 to 9 using binary numbers and resets back to 0 after 9, which is useful in digital clocks and other electronic devices.
We got a new inventioneer!!
I loved learning about flip flop
I think R-51 sould move that circut to a more secure place.
I loved this science live alot, was a fun one thank you guys for doing these weekly! Water Spiders are cool.
I love going on to science live every week
I liked when Dr. Billings was talking about circuits because that was interesting
my favorite part was learning about water spiders.
i learned that mirrors reflect the color of the rainbow and lightsplitting.
I think Dr. Pajet is an angel. She changed so many peoples lives including mine. Thank you so much Dr. Pajet Monet!!!
when will we have flying car
Awesome science live video! Loved the water spider.
This was so fun to learn about.
Acd2 was an adorable robot I loved his dance moves and song. Also the video describing how to make the binary decade counter and the frequency divider was very fun to watch. The “he likes your shoes” cracked me up.
I Love this science live today!
Very entertaining to see! Love Science Live, keep up the good work!
Love learning with Acellus!!
This was such a fun live! I can’t wait for the next one!
Thank you for this Science Live episode
I love how informative this science live was!
I almost got a heart attack when the circuit almost got destroyed
Wow! the water spider was really cool to learn about!!
I like the part where they were talking about the water bouncing off the lines like it didn’t want to be there.
Every week I learn something new from these lives!
I love this live, the spiders are so interesting to learn about.
yay another science life 😀
Water spiders! That just blew my mind! thank you for bringing us this video.
I loved the water spider!!!!
I want that robot that dances.
It’s wild how an eleven year old decided to learn how to animate.. that must have taken a lot of time!
how can it move can it fly or because its a gyroscope can it balance itself on water
Can you do a video with the female inventioneer? PLEASE!!
I liked the dancing robot! He was cool. I want to earn gold coins to get one, too.
i didn’t know circuits was that easy to make i learned a lot of stuff in that video thanks you.
I love science live they always teach me a lot
Always love the weekly science live videos, so fun and interesting to watch!
I did not know there was so many different types of transistors.
the song was good
The water spider is really cool!!
When will we ever explore the whole ocean?
After a horrible storm in my area, I’ve been out of power and wifi. But now that’s restored, I’m glad to be back for this Science Live
I loved this science live! It was so cool to learn about the water spiders
It’s interesting that colors have different temperatures. I knew that the reds, and oranges,
and yellows were called “warm colors”, and that the green, blues, and purples were called “cool colors”.
But I didn’t know the reason they were called that was because colors actually have different temperatures.
That’s pretty cool!
The decade counter, the flip flop, the 7-segment display, the 7-segement driver, and 555 was so cool to learn about.
I don’t like spiders. I am arachnophobic.
the robot was cool
I am now starting to understand how the circuits work, thanks!
The decade counter, the flip flop, the 7-segment display, the 7-segementdriver, and 555 was so cool to learn about.
I LOVE SPIDERS <3
How did the 555 circuit get its name?
Super cool about the infrared light! I’ve been wondering how it worked for a long time!
Science Live brings so much new knowledge to me. I can not wait for the next one
Really enjoyed this live. I did not know that the colors were actually measured in temperature, that was pretty cool to learn.
i love the protoges so much lol
Spiders freak me out but i liked learning more!
Infrared light is so cool it looks like a halo on his arm where his arm was moving
I thought it was interesting yet confusing on how the water spider spends their whole life underwater but cant breathe underwater.
spiders are amazing!
This science live was phenomenal! It was so cool
Circuits blew my mind!
thank you so much, I loved hearing about water spiders and circuits!
i loved learning new things about computers and science, its really fascinating!!!!!
I love spiders!!!
I really enjoyed the part about the rainbow and I had no idea about infrared light and ultraviolet light! And R51 is so funny my highlight of the whole program!
I LOVE ACELLUS
I already knew a lot about wavelengths and the infrared and ultraviolet scale, and this helped me remember some more of it. Another interesting thing was hearing about the water spider and how it survives by the bubble/web it creates. The thing that really caught my eye was learning about the different circuits and how they work. The most interesting thing was learning about a flip flop and how it works. I never knew how many different circuits there actually were and that they all worked differently.
Science live is fun!
I love spiders. And now I thank the water spider is now my favorite one. By the way, my birthday is tomorrow
I wonder if they can make something bigger float.
I loved this weeks video!
I loved this science live I really enjoyed learning about the spider that can breathe underwater.
Before today I didn’t know there was such thing as a water spider. So cool!!
I didn’t know water spiders exist!
Learning about the water spider was intriguing!
The water spider is so cool!
What is a binary to decade counter
always makes my week 10/10
i love science live so much! i didn’t know water spiders can make there home under water.
I learned about binary decade counters
