Very interesting science live
I love R51
I like learning about comets
R51 is all ways the best part.
Comets are cool!
How did scientists predict the arrival of the super comet?
this is so exciting! i love these videos!
Looking forward to the comet of 2026!
How cool that train that they build in 1964.
We loved watching this live. I love learning about the bullet train.
The science fair is so cool!!
I’d love to ride on a bullet train
I love that you give students so many opportunities whether it is bringing them onto these science live videos, or if its the science fair!
The bullet train was awesome
could you use magnets on the bullet train to have it levitate and go a lot faster?
Im going to invent something great one day!
I loved watching this! I can’t wait to learn more on the next science live!
I loved this weeks science live!
another great video on science live
I had always wanted to do a science fair, But never was able to understand how to start or do one. thank you so much for explaning it step by step and making it easy!!!
I can’t wait to see the comet.
It’s so cool to see how fast the trains can go! Also, marking our calendars for April 20th to see the comet!
It was interesting to learn about the innovation behind bullet trains and Japan’s role.
Thank you for science live I learned so much
Great video this week! I liked the bullet train.
Cool video, I liked learning about bullet trains. They were always pretty awesome so learning more about them was fun.
It’s funny how the internet is so diverse and the computer programs are just 1’s and 0’s
I learn so much from science live
love the video keep making them
This was an amazing science live. It was one of my favorites yet and I can’t wait for the comet.
I loved this science live
Acellus is very enjoyable and peaceful, and its videos are very quick but entertaining, I enjoy watching their videos.
This was a really good lesson!
Hey, I live in the south! Maybe I will get to see the comet too! That would be great!
These videos are the best!!
Another great science live!
The speed of the bullet train impressed me!
I liked learning that there is going to be comets in 2026, some of the comets that are coming in 2026 are visible and more grey if you look in a telescope, Dr. John naming the one of the comets that is coming in 2026 Pajet’s Planet, People were fixing wires in trains for 5 hours, News sources saying that the bullet train was traveling very fast in 2018, and I liked seeing Cody’s circuit the P2.
I loved learning about how all computers work using ones and zeros.
Hiii from nc
How do you make circut boards?
I love learning with acellus and science live!
I am really looking forward to seeing the comet, I know my whole family will be outside looking with me. I’m glad I was able to find out about it from this video!
r 51 makes me laugh every science live.
Comment it was interesting to learn about Comets. Thank you.
Video was very interesting. Cant wait to see what else there is!
The thing about the trains was pretty cool.
The bullet train was awesome!
Hello from Kentucky!
I wish i had an R-51 of my own!!!
that was awesome
I loved Dr. Tobias’ segment!
I love learning and watching these videos with Acellus.
R-51 is always the star! Love to see it!
I loved learning about the bullet train. Awesome information!!
The bullet train going over the bridge was very cool. I was wondering what a navy jet going over the same bridge would look like. We’re even a spaceship. Will we even be able to see how fast it goes?
It’s interesting knowing that computers all work using ones and zeros
I learned Thomas Edison has same birthday as National Inventor day. Thats so cool.
These videos are so awesome I learn so much from them!
Thank you for explaining the steps for planning a science fair project. I think I would like to do one.
Thank you for explaining the steps for planning a science fair project. I think I would like to do one.
Love R51 he’s funny
Happy (belated) Birthday, light giver!!!!
I can’t wait for the great comet of 2026 it seems awesome
This episode was very interesting.
Its going to be so cool
Love learning with Acellus!
Another amazingly educational science live, also love the comedy that I am not sure is intentional or not but whatever, also, the reactions to the train? Priceless, excited for the next one!!
R-51 was the best part
I especially enjoyed the discussion of a comet. Anything space related though is always a treat! Thank you for an interesting night!
Can’t wait to see which comet ends up being the true super comet of 2026
I love these science lives they teach me so much
The bullet train in the video went by so fast that if you would have blinked you would have missed it!
This is so cool!! I loved this science live.
I’ve always been so mesmerized by the Bullet Train!! It’s always been so interesting to me!! I also can’t wait to see which comet is the super comet of 2026!!
Oh my goodness, David and Caleb are so funny, they always make my day!
Loved this live so so much. He’s such a cool guy! We should name the comet after him!
I cant wait for the great comet of 2026! I wonder what it’s name will end up being.
I like the bullet train and the faces on those people. it was so funny. I like those eventors. I also like r51 but when he has that spray im staying far away from him.
Dr. Billings, you talked about riding the bullet train in Japan! That is so cool! Nihongo ga hanasemasu ka?
I cant wait to see the great comet of 2026!
The people’s reaction to the train was priceless.
Thanks for always expanding our minds!
I’ve never heard comets referred to as snow balls. Thinking about it that way really helps show how they “melt” as they fall.
how did scientists predict the arrival of the super comet of 2026
I loved when these videos come out every week and we get to learn new things. I thought it was cool to also hear from different teachers and learn different things.
Loved this live, I love that this school focuses so much on teaching us science! My favorite thing I learned in the video was about the comets, I cant think of a name for that comet right now but I’ll keep thinking!
Acellus is soooo cool!🤩
The bullet train’s speed impressed me.
LETS NAME THE COMET R-51!!!!!! PLEASEEEE
Great Science Live this week!
R51 is so much fun
The invetioneers were so funny! I loved the contest and the skit on the moon.
R-51 is not a waste of time
honestly R-51 is never a waste of time
As someone whose name starts with “Z”, calling that comet “Comet Z” would be cool, hehe. Also, I don’t trust r-51 with that shrinking spray.
The 2026 comet is going to be so cool!
National Inventors Day cool👍
Great advise Dr. Tobias gave, stick to the plan for projects!
I’d love to have the opportunity to ride on a bullet train one day! Very impressive!
I’m so impressed by the trains. I love Acellus!!!!
Loved the Never Gonna Give you up part
I LOVE THE END WITH THE SPRAY!!!
I think bullet trains are really amazing because although they are fast, they are extremely safe and comfortable.
The bullet train definitely speeds up traveling
Speaking of inventors day, what is dr. Billings favorite inventor of this generation?
David and Caleb are such great additions to Science Live. Their segments are always funny, educational, and interesting. Thank you for this Science Live this week.
The comet should be called c-51 (invented by r-51). What causes the different colors of the comments and what determines how bright a comet is?
Great Science Live this week! I was wondering if you will announce science fair winners on a Science Live? Also Comet Z is an awesome name!
lol Caleb is my favorite!! He’s so funny!
5 hours to fix any issues? Do they know the issues ahead of time in order to plan for it and get the materials ? Also no casualties is impressive
I enjoyed learning about the bullet train and the circuits. Can’t wait to watch the comet of 2026.
It’s so much fun to learn about various scientific discoveries!
Hello from Oregon. My grandpa is an engineer on trains, but not bullet trains, that would be cool though. Happy Presidents Day!
I really enjoyed the segment about the inventors making circuits. I also was fascinated by the bullet trains, they’re incredibly fast.
I like the idea of the science fair videos so we can be more connected with Acellus
what impressed me the most was him being able to remember his dream and now being able to see it come true.
The Great Comet of 2026! We should come up with some fun, creative names for the upcoming comet. I love that Dr. Billings had the same idea. Great minds think alike.
I loved the train it was so cool!!!!!!!!!!!!🚆🚇🚅🚄🚉🚊🚃🚂 would the new train that they made be faster than a jet or a plain? Becuse the train took 2 and a half hours instead of 6 hours did people still drive or did most of them take the train? And it was sooo cool that the train can go 180 mile!!! Thank you for this Science L!ve!!!!! Can’t wait for next week!!!!!!!!
I loved hearing about the Great Comet of 2026. I think we should name it The Galloping Inferno. That goes along with the Year of the Fire Horse, galloping into the sun’s inferno! Looking forward to this amazing event!
I think it should be named, Tobias
With the upcoming “science fair” and the “AC-D2 dance robot contest” coming up, I have a question. Is it required to have the AC-D2 robot in order to participate in the contest? Some students might want to participate in the “AC-D2 dance robot contest” but do not have a robot to use. The steps to participate and to submit the video said nothing about whether the student needed a AC-D2 robot in order to participate. Can you please clarify what is required?
What are the ingredients to R51’s shrinker solution? And the protajaies are really funny.
National inventors day being on Thomas Edison’s birthday is so cool.
lol that was probably my favorite lesson so far. It is crazy how fast bullet trains can go but also how integrated circuits can be in all different sizes and can be used for many different things.
I have always been interested in bullet trains. These trains are really important to travel in Japan, and it was really cool learning about them. Also I agree with Dr. Billings, let`s name the new comet “Comet Z”!
Are all the rest of the science lives going to have Dr. Billings sons in them, i loved the astronaut skit!
It was very interesting seeing how computers have changed from the 1940s, and learning about how integrated circuits changed their size.
what impressed me was how fast the trains went
love Acellus love if I home school my kids it is going to be Acellus.
I watched the video late again however, this is another wonderful video teaching me great facts about technology. These videos have been helping me work through the doubts about my future and cheering me up when I am low. Thank you Acellus!
I like how he included national inventors day! So cool
I love science live !!!!!!!!
I likw how he included national inventors day! Thats so cool!
It was so funny when R51s assistant was getting chased by an ant.
Bullet trains are so cool, I wish I could ride one!
Personally I think that Circuits and how tiny they are, are super cool.
Please do more episodes like this! I really enjoyed how different it was.
Learning with dr tobias is fun!
That’s a great Thomas Edison joke! Happy national inventors day!
does r51’s assistant stay small?
I like the name Lovejoy we should keep it!
I also loved learning about the bullet train and circuits. Thank you.
Science Live is cool.
Good morning! Loved the video! Hope everyone had a good weekend!
Science Live was so much fun!
love r51
I loved it so cool
look forward to these lives every week!

The comet part was super interesting cool science live in general.
They make throwing rocks/boulders in space look so easy!
Honestly, I think that Eddie’s idea was amazing, and the comet should be named Acellus!
I’m ready for the Japan train
i think national inventors day is cool
Trains fascinate me, thanks for talking about the Bullet trains in Japan!
It was so interesting learning about the bullet train!!!
I loved the bullet train part that was my favorite!
Could you explain how a rocket thruster works and how strong it is?
A cool fact i learned was bullet trains go 130mph!
I love the intro of science live so cool
The explanation of the bullet train was so intriguing.
I’m so excited to watch this week’s stream!
I think the comet should be named a cellular after our school. That would be so cool. I love to watch science live ever week. I love the intro of science live
I think the comet should be names Max
I think the comet should be named a cellular after our school. That would be so cool
I love seeing another great episode!!!!
Thank you, good show science live.
What would do without electricity. Thank you, Thomas Edison.
I do not even know how to respond to the discovery of this information. I do like the comet part though.
