This video was so intresting . I loved learning about Integraed circuits. Can’t wait to go to Acellus world.
Just started this program and I LOVE IT!!- sent from Texas.
I really liked this video, i do coding sometimes myself so it’s really nice to see other people teaching stuff like it.
I’m a flip flop btw lol
I wonder how long it took to program the robot to dance.
This was my favorite video so far! The big robot, the spider, and learning more about the science fair and Acellus World online was so cool! Thank you!
I loved this live it was so cool
yas. how do you change the speed of like how the pulse
Would our robot friend every have an upgrade in the future, perhaps something like arms?
Great show tonight as allways!!!!!!!!!!
I loved science live today 😋
I know this might sound crazy but here me out
New conspiracy theory
The protégés are really just test subjects for r-51 to experiment on. Like he said he just created the serum and he never thought it would work on protégés. It almost seams that as he’s experimenting on them he is preparing them to become teachers. As we saw in the little clip when they drank the serum David gets a vision of doctor john whilst Caleb gets a vision of lady pajet. Not only do they get the visions of the teachers but they also get the knowledge and experience of them. Might be a little foreshadowing going on here.
Hello from NC.
When was the first rainbow found?
I LOVE THIS!!!
Its cool how william hersho thougth about sir isaac newton and about the colors and it cool how the mittle can flout even whith holes
I like how David and Caleb explains things.
It was great my favorite part was the Area 51 guy
It’s amazing to see what nature is capable of, and how humans have advanced their technology by taking inspiration from it.
How long dose it take to make one of those tubes hydrophobic?
Good night everyone and see you next Wednesday.
A decade counter is a digital electronic circuit that counts ten distinct states between numbers 0 – 9.
A integrated circuit is a tiny self-contained electronic circuit consisting of interconnected components.
Saying hello from Tennessee!!
Amazing live these lives are so fun to watch!
Hello from Illinois! I’m glad to do a science live with everyone. I love the part where you made a robot and it looks just like the real thing!
I really liked the video. I loved AC-D2.
This is so interesting! I love Tobias’s talking!
That video was very funny!
I love how much you can teach me in one science live
hi from Georgia, cool video
I never knew there were underwater spiders
I love the live stream. I loved the segments on this one as they were visually appealing and very interesting to learn about! I feel the social emotional class is very important as well. It teaches how to control behaviors and how to make a positive impact on the world around us!
The protégés like broke R-51’s circuit then fixed it during the question to talk about and drank the Acellus Teacher Serum lol
Can you use one wire to run two circuits?
Wow so excited!!
love science live ❤️
Hi from NC.
This was another amazing episode! I loved learning about all the different parts of a computer chip!
The Protégés are so funny. I can’t wait for every weeks Science Live with the Protégés. Keep up the awesome work.
love what yall do
Great job Mr.billings with these lives. Looking for towards nexts week video!!
Love learning about metals and science in general in science live, how doe r-51 manage to make me laugh everytime. Love science live and will see you guys next week!
I FEEL like these comments are botted but I have no idea if they are or not.
Thanks for since live it helps much needed *
Are the protegéis getting a new member too
Cool science live!
I really enjoyed today’s science live!
Hi from PA
My top 3 personal favorite moments in Science Live:
3. R-51
2. Breakthrough Moments with Dr. Tobias
1. The Proteges (David & Caleb)!
hmmm… I think I’m more of a flip flop.
I didn’t know she was the same person that teaches sel,I also liked what the prodigy’s taught today
I like the robot dance and the protege guys are so funny.
I’m very excited about Acellus World. The way the robot was programmed to dace was impressive. Great job and live.
This is so cool and interesting.
Hi again everyone I thought this was a very educational video and something I found interesting was Kelsey because she made her own animated film, she is a model, an actresses,and voices two of her own characters in her animated film. I thought that was very impressive.
I think the “hydrophobic boat” idea with holes would be a pretty bad idea because I think it would make the structure of the boat more fragile.
Hello from Alabama
Hello Science Live! Again, I love the part of the proteges, and it’s honestly my new favorite part of the Science Live! Thank you Acellus and have a fantastic day!
Hello, from Texas.
I loved this live and I loved the robot. See everyone next week!
Hi from Wyoming! Awesome video
Such a cool lesson thank you!
Wow all this stuff sounds so cool!
Hi my name is Malak And I,m from Minnesota
Hello from Georgia!
The temperature on the light wave lengths was awesome.
I like how he tried to figure out how just one white color shined on a glass can make every color using heat and other stuff!
hi, tuning in from Arkansas.
I love watching the videos. This was my first time watching it live
I love expanding my knowledge and discovering new information that I did not know about.
The explanations for the circuits really helped me understand how they worked.
How did we make circuits small enough to fit in modern electronic devices?
So interesting! Loved this weeks Live!
I love your videos
R-51’s serum worked perfectly, I need that serum I want to be as smart as a teacher too.
Hi from Missouri! Seeing the robot dance was cool!
I’m back from break. Now I am in 8th grade. I liked the science live today. And my brother does coding. He took two of the classes now he is doing the third one. Meanwhile me I’m doing ASL.
Hello from Florida so cool

I can’t make it to Acellus World, so I think that making it available to be accessed online is a good idea.
I love r51 he is so funny.
Binary coding is so cool.
The protege’s are the best addition to Acellus yet in my opinion. They explain everything very well.
Inconcievable
This science live was amazing, the big robot was so cool!
