Another great science live.
I never knew bullet trains worked like that.
So interesting I love these videos.
I thought this video was really interesting! I wish we had trains that could travel that fast in the USA. The circuit section of the video was also really cool to see and made me interested in building one myself at home.
i love these science lives!!
Now much does an bullet train cost?
I love this episode!
The fact we can still see those comet fragments all these years. Ty science live
I wonder why we still dont have a bullet train in the US
The integrated circuit was really cool!
Learning about the bullet trains are interesting.
I really like learning about integrated circuits! I love working with circuits in school.
Very good directing and acting by the protégé’s!
Crazy how the bullet train design has changed so much
I had no clue national inventors day existed until today.
I love these so much! A little bit ago I learned some things about circuit boards, but this really helped my understanding of it!
I LOVE SCIENCE LIVE
I loved this episode!!!! Very informative!!!!
Integrated circuits was definetly a big step to computing and all that kind of stuff
I learned that in order for a computer to reach the moon, it would take a device as big as a city and enough power for multiple nuclear power plants. WOW!
hi from ky
hii from illinois
That comet was incredible to look at!
the science lives are so entertaining
The integrated circuit is really interesting!

18 months for a commet to be visible is crazy!
Thanks for the info on integrated circuits!
I Liked the integrated circuit talking.
The Bullet train was very cool!
circuits are very interesting.
Would the energy of waves be considered renewable energy? How much does it cost to build a acd2?
My favorite part of this episode was learning about the train conductors!
Can you make a clock using integrated circuits?
Thank you for helping me understand a bullet train. It really cool how they go so fast.
Bullet Trains are just so so fast.
This was by far one of my favorite episodes!
how bright does a comet have to be to be able to see it during the day
I love bullet trains!!! I can’t wait for them to come to America!!
Bullet trains and circuits are interesting.
Really enjoyed this weeks science live, computers are so interesting!
I loved the Bullet Train!! I think it would be sooo cool to ride on, the speed is incredible.
I find technology so hard to learn! Props to all the techie people out there
SCIENCE LIVE IS BACK BABY!
Did the technology limit what the astronauts were able to accomplish?
How reliable was the technology, the engineers used to talk to the astronauts?
The bullet train is so so cool! Amazing that they didn’t give up.
Very interesting, helps understand the technology we use every day.🙂

This is so interesting and awsome!
another great week!
Hello from conway
Hii everyone I hope your having a great day!
I love how they made kind of like a show lol
Amazing science live, look forward to tuning in next week.
Watching from Texas
Madisyn here, I think the comets name should be Snowball the comet!
always looking forward for this videos , Bullet trains are my favorite
Man, I love Circuitry
It was so cool to hear about the comets coming in April. Can’t wait to see them.
Space is really fascinating. Can’t wait to see the comet!
R51 is so iconic!!
It was interesting to hear about circuits and the first computers
It was interesting to hear about circuits and vacuum tubes
This was so fun to watch!
A hey from Texas
Another great episode can’t wait to watch tonight’s!
Hi from texas ready to learn
Hi from Florida
i think the bullet trains are interesting
The introduction of the integrated circuit changed technology by making electronics smaller, faster and more efficient.
This is was so interesting to learn about.
That bullet train must have been so cool and fast
One of my favorite lives.
it was interesting and very cool to watch Dr billings talk about integrated circuit

That’s super cool! Great episode!
What grades are allowed to submit a science fair project?
HI FROM CALI
I love learning about space and seeing how beautiful the planets and comets are.
I loved this episode!
I loved learning about the train in Japan! It goes so fast! Thank you for another great video!
I’m excited about the science fair!
such great weekly videos!
Bullet trains look so fun.
Integrated circuits are very interesting.
Who discovered the first comet?
Science live is awesome!
The difference in speed between the regular and the magnet powered bullet trains is incredible! I’m curious as to how fast they can stop, and how long it takes them to slow down to a stop when there are passengers on the trains.
I love these videos. Always something new.
I didn’t know what bullet trains were until now. They’re pretty cool!
We love science live
It is very nice to hear and learn more about commets
Bullet trains are genuinely so amazing to me. I think with what the future can hold, technology on them can surely upgrade a lot, such as making them even faster than they already are, with of course safety measures. Imagine a smooth 100% free of danger bullet train that can go lightyear fast enough safely, AND can travel across the world country to country perhaps in just a few minutes? It would be insane to say the least.
Bullet Trains are so cool!!!!!
Comet Z sounds nice, but why not Comet A and just keep naming them after letters?
Hi! from NY!
Hello I’m from Texas
Bullet Trains are so cool!
