Thank you for explaining something knew it is always interesting. I loved the way you guys explained this topic.
Can’t wait for the comet!
A science fair is so cool thanks for the cool and new opretunites
I love comets!
I did not know there was a national intertor’s day.
I really enjoyed the extra long video from the protégés. They explain things very well its a perfect balance between fun and educational content.
I think comets are cool.
I love learning about the comets! Thank you for sharing this awesome information
One day can the proteges and the ventineers do a collab with R51
I loved the part about trains!
Thanks for the video
Bullet trains are definitely a one of a kind invention I would love to be able to ride one someday and experience the speed they go myself to be able to say I’ve been on one before.
This video was one of the best I enjoyed watching it, and I think the name for the comet should be CometN.
hello everyone! I loved today’s video i love Thomas Eddison
thank you for doing these videos😊
Science live rocks!
Acellus Comet ( AC) would be really cool!
Happy late valentines day everyone!
It’s interesting to learn about the fast trains in Japan.
Thomas Edison should have his own holiday lol, or name him after the comet
We need electricity for a lot of things in the world!
Its interesting how from different places in the world can effect how we see certain things in space.
I like Area 51’s jokes!
125 per hour is crazy
That was such a interesting video!
The end was so funny
The bullet train is so fast.
circuts are so cool
Can’t wait to learn about this
what is a comet
I think the comet should be named will the wise.
I’ve ridden in a bullet train before.
It was comfortable, fast, and fun.
will be looking for the comet!
I cant wait to see the comet!
so cool. Cant waitvto do a science fair project
I would love to see a real comet one day. I like learning about it on the science live. Comets are cool.
The comment sounds super cool!! When is it coming again??
I really liked the David and Caleb part. Getting to learn about integrated circuits, vacuum tubes and computers was kind of fun
I loved everything about this episode it was hallarious and educating i loved it so much thanks science live
I like comets.
Can’t wait to see the next Comet. *
Very excited for comet!
It’s crazy how fast the trains go!
I like the part about trains. I really like trains.
I have a question,, are shooting stars actually just comets?
I like the part about how cool comets are!
I would really wanna ride a bullet train one day.
I didn’t know that there is a national inventors day, that’s really cool!
Ill be on the lookout for the comet!
That’s a good idea, I’m gunna try to memorize the periodic table too.
Do you think we could stop a comet from hitting our planet if it were directed at us if we knew 4 years prior so that we could prepare?
the comet will be exciting!!
Yeah they should call it after our school’s name.
I love that science live video. I am going am going to Japan so I am going to ride one.
I will definitely be on the lookout for a comet!!!
Integrated circuits are cool
this was a cool lesson, I really enjoyed it.
Astrology is so fun!
Hi, my name is Daniel I love science I want to be an engineer one day and do you wanna know coding cause I just did coding and I’m very good at it
david and caleb had me laughing so hard, what with the editing and their humor
I wish I could attend the science fair. 🙁
i loved learning about the comet i love thomas eddison
I love Science Live! How many of you kids are in 7th grade? And about to be in 8th grade in a few weeks. 😃
What is the name of the first person to discover a comet? I really enjoyed the show this week.
awesome video ♡
A comet really!? That’s so cool!
Happy National Inventors Day!
This is my second time watching this science live! Mr. Tobias is really cool history teacher.
Never knew there was a national inventor’s day, thats pretty cool though.
Happy late Inventors day! thank you to all the inventions!
How long did it take for the bullet trains to be out of the test phase?
Hello , from Miami🌊☀️🏖️🏝️🐚
theres a national inventors day that’s awesome
Do comets usually come in the average same size?
How large is an average comet?
Comets are so cool.
How long would it take a comet to go around the earth.
I didn’t know national inventors day was a thing, how cool!
how do coments form?
Since all of the US is on the Northern Hemisphere I might be able to see the comet.
love this live keep up the good work!
Learning about the comet was interesting and will be on the lookout for the comet!
We will look for the comet! Please have Mark Roger’s do all math lessons!
The joke was actually really funny, I loved today’s radio show
Another great science live
cant wait to see the comet!
Comets are awesome!
I liked the protégés
I love science live!!!!!
Hi from Oklahoma! I really enjoyed this episode!
I think it is so cool to be able to see a comet that is so bright!
thanks for this awesome new info.
Do you think this comet will be a big event like the solar eclipse?
I like the trains.
Comment I think a really good name for the comet is The Harrington.
How do the really small computers work and what do they do?
The comet is so cool definitely should be named after Acellus or R51.
Happy Presidents Day! And happy delated Valentine’s Day!
Science live is very cool!
I think riding a bullet train would be very cool, it’s crazy we’ve been able to make stuff like that.
love learning cool things like comets!
I love acellus.
who first named a comet
I love learning about cool stuff like comets
The Magnetically powered train sounds awesome if they can get it done!
z comet !!!

How do commets come to be?
really liked the you build it we judge it part.
Omg! tell me more!!!!!!!
We will for sure have to watch for the comet if we can!
I’m hoping to be able to see a comet!
The commet should totally be named Scientifico !
I learned alot about circuits.
Comet around 4-4-26!!
I think the comet should be name pepper
When you were talking about comets, I thought if I ever found a comet I wouldn’t even know to use my first, middle or last name when naming it.
I had no idea a train could go that fast.
When is the new bullet train expected to be available for the public to use.
Ooooh, I can’t wait for that comet!
What is the new comet called?
Bullet trains are such a good innovation, I would love to go on one!
I think the comet should be named Acellus after our school.
I love comets and meteors their so cooool!☄️
I liked this video. Thank you
That comet was really cool!
Thomas Edison was incredible. He changed the world as we know it by introducing electricity. I think the comet should be named Blaze, representing a fast and fiery spirit.
I love to learn about comets.
What is an integrated circuit, and how is it different from discrete electronic components?
We rode on a train once in Colorado! Interesting facts on Japan’s train.
this video is very informative, these comets are the coolest
I’m so excited for the comet!
The Comet definitely should be named Acellus
I really loved the information I was given in this session it is really amazing what the world has to offer.
It’s so cool how trains are super fast now and before they were really slow
i love circuits.
This one was so good
i loved what you had for us this week and R51 shrinker was cool
Good time to use my telescope!
The bullet train sounds cool!
Happy Monday!
