This was a very good science Live.
The comet should be named Comet Blazen!
Japan and the Bullet Train
This science live was so good! I can’t believe how many good facts there were. I love the science lives because it is entertaining while learning something new.
I LOVE SCIENCE LIVE
I haven’t seen a comet but want to now
I like learning about the comet
HI I am from NC
I love science live, i learned so much from it, Thank you
I really enjoyed learning about the bullet train in this video.
Very interesting information about comets.
Bullet trains are so cool.
Thank you for teaching us about electricity, conductors, and semi-conductors. It is cool to see how circuits work and communicate.
I am glad you went into overtime for R51. I just love him.
I will definitely be watching for that comet in April!
I love science live❤️
I enjoyed watching the bullet train part!
The protoges were really funny!
I like learning about comets
Hearing about the comet is super exciting!
I like learning about comets.
Love the science live!
Excited about the science fair
I love astrology great video!
Amazing!
I think we should name the commit area 51
I’m so excited for the comet this year! Learning about integrated circuits has been really intriguing. God bless you!
I will be on the lookout for a comet
I think the comet should be named Comet-R51.
I second Eddie’s comment!!
We love science live!
The guys are so funny and the Competition
I really like the circuit show!
Comet is great!
Hi, from Texas!
I didnt know comets could last 1700 years. That is really interesting and cool!
I think the comet should be named ” Roger’s comet.”
I love trains. I want to ride a bullet train someday.
Very interesting video they should make more..
I’ve seen that white bullet train before. It’s really fast.
I really liked learning about the great comet of 2026!
I loved seeing the circuit section as someone who is interested in getting into them i def apppriecatiet that
My favorite part of science live is those two guys and R-51, no matter what DrB says. Also HAPPY VALENTINES DAY
I would name the comet six-seven comet of 2026. I didn’t know that computers took up a whole room.
I liked learning about the fast moving train in Japan.
I really liked the depth explanation of the different parts of the comets!
I think that it is interesting that bullet train’s average speed is 130 mph. Also, I think R51 is not a waste of time.
How did inventioneering guide your approach to building the Billings Computer?
It is very cool and interesting that there is an inventors day and that it is on Thomas Edison’s birthday
today is natioanl inventors day and i didn’t know that.
Are there limitations on integrated circuits?
My favorite comet is Halley’s Comet.
I like seeing things from outer space! Can’t wait for next week live.
What is the brightest comet in the world?
I liked this weeks science live.
I’ve heard a little about the bullet train but that’s super interesting
Integrated circuits allow us to go the moon! That’s amazing!
the comets so cool
The best part of this LIVE was the secret shrinker solution. I thought it was funny when the assistant shrunk a few things including himself. 🙂
I never knew there was a national inventors day!
I will be on the lookout for a comet for sure! Anothe amazing video thanks so much!
That’s crazy that a train can go through a mountain!
My favorite part of this episode was during the “You build it we Judge it” segment. The contestants had to make a circuit using an integrated circuit. When the hour was up and Cody put in the final battery, the light turned on and off and I couldn’t believe he got his circuit to work. It was fun to watch!
As always lovely video! Cant wait for next week.
I’ve never seen a comet, I’ll be looking for one now though.
We will definitely be on the look out for a comet! They’re interesting!!!!!!
Enjoying Acellus!
Congrats Cody on winning the contest!
The Bullet Train is so cool!!
What would we do without electricity?
how did they make computers so giant?
I think we should name the comet ACELLUS X.
hi thanks for the scientific live for wednesday
comets are so cool
It was really fun and interesting getting introduced to integrated circuits!
this is awesome!
I love this so much😒
I think the comet should be named Dream Star since it came from your dream sort of R. Billings.
Loved it again! I am really into tech and this is a cool series of things we have been talking about!
its really cool how inventers think of things
The science fair projects look like a lot of fun
i think everything in this is inspiring!
Wow! I’m so excited for the asteroid of 2026!
Wow! I love watching these, they’re always so fun!
I have always loved Japanese bullet trains. I’m thankful that they didn’t listen to the haters and every thing turned out amazing!
Thanks, for this live! It’s amazing to see just how fast bullet trains go!
A comet named after the school would be really cool!
I think its really cool that they made a national inventors day.
Science Live is so cool!
Hello! I’m from Japan and I rode that train that Dr. Tobais told everyone!
If you come to Japan, I recommend you should ride it! I’ll be waiting in japan!
I really how they shrunk the computers.
I love Science Live! I think that the comet should be named, Whiskers Comet.
How often do comets show up in our atmosphere?
Can we learn more about the bullet train?
Can’t wait for the comet, thank you for science live!

Watching from Illinois
I look forward to this every week.
The science fair sounds like so much fun!
This is probably my new favorite video so far and I loved the part with the proteges and inventioneers!
I love home schooling!
The comet sounds super interesting! Loved learning about it and how they travel.
I love the part where the rules appear and you have to follow all of them
3 more weeks until the 300th live!
It is on my bucket list to ride a bullet train when I someday go to Japan. Love them.
they should name the comet something like, ” dream” or “esplodream”. now I wanna ride those trains :3
I love science live.
For the bullet train dose the spring need to be replaced often, or are they strong enough to last for years?
I like the name Glimmer for the comet.
i love learning with science live.
so excited to see this comet!!
I went to go to Japan some day
I liked learning about integrated circuits
This was a very good video I love science live
I automatically think of Japan when someone says bullet train. Crazy to think they almost failed. Also either the video editors are really good or they’re really good at using AI because the animations today were top notch
I always wanted to see a comet. I think they are really cool.
that train went fast. It was there I blinked and it was gone.
I want to do a science fair project!
I am so excited for the science fair.
Thank you for this weeks! I’m really excited for comet too!
Thank you for making this one about circuits! I appreciate your comments’ involvement in your episodes!
Comets are very interesting!
Learning about the bullet trains was very exciting.
integrated circuits are so awesome
I liked learning about the bullet train and the great comet of 2026
One day can trains be faster then planes?
Thank you for helping me learn.
What a fun episode, love when your family is part of the show.
I want to ride the bullet train in Japan.
This is so cool and educational!
cool how bullet trains work
I think the comet should be named unite because, we all unite in this school all together!☄️
how can something so small do so many things at the same time ?
i think the comet should be named acellus
what is an integrated circuit, and why do computers need it ?
excited to see the comets this year.
I love astronomy and will be on the lookout for comets!
I have access to a telescope with an 18″ mirror!
Great introduction to integrated circuits in this Accelus episode! I really appreciated how it clearly broke down the fundamentals—starting from basic semiconductor concepts and building up to how transistors are integrated into complex ICs.
# Acellus Comet
