I like how yall are doing a science fair! Thanks for making another live. Happy valentines day!
The bullet train is an amazing invention, nice segment.
I liked learning about the bullet train, it went so fasgt!
Happy valentines day everyone! My cats hope you have a great day! :3
How many times have I watched the Bullet Train Segment? The answer is just yes.
How did you become interested in science?
Happy early valentine day can’t wait for next live!!
my favorite planet’s are earth mars Jupiter Pluto and the sun .
Thomas Edison is so cool!!
Happy Valentines Day!!! I absolutely love how fun these videos are!
Wow! The comet looked so cool!
I think we should call it ” Acellus51″ or ” R51″.
Happy Valentines Day!!!!!!!!!!
Wowww these videos are my favorite!!!
I love science live !!!!
happy valentines day!!!
That is so crazy that computers where running by switches and tubes.
Great video! Awesome to hear about National Inventors Day.
how many mphs does the train go and I can’t wait to see the commet
It is crazy how fast a bullet train can move, and how much distance it takes per a second.
The Projees are funny
how do you do stuff with circuits?
I loved the portion about the comet. I think that comets are so interesting!
I love R51!!!! It is soooo funny!!!!
Super Interesting!
Happy Valentines day! Can’t wait for the next science video!
I liked the long fast trains we learned about in Japan. I would love to ride on one.
Good to know!
r51 is so cool!!
Happy Valentine’s day!!!
This is the funniest science live I have ever watched. And I think we should name the comet. Comet blaster!
I think r51 is hillarious and I want to ride the MagLev train one day!
R 51 is NOT a waste of time. It was extremely interesting to learn about the train in Japan.
These videos are GREAT!!!!!!!! I love r51!!!!!!!!!!!!!!!!!!!!!!!! He is the BEST!!!!
Happy Valentines Day Everybody!!!!!!!!!!!!!!!
I thought today’s episode was exciting and intriguing. My favorite part of the episode was Dr. John Technology spotlight. Learning about why comets have 2 tails was interesting, I never realized that the two tails were that important a comet. I can’t wait to see the comet that’s apparently coming this April, it potentially being as bright as the moon is amazing. However, I wonder if this comet is also a part of a bigger version of it and maybe one day it will come around someday too? I thought every part of today’s episode was wonderful. I can’t wait to see you next week Mr. B and Happy early Valentines days!
Dr. Tobias, do you think we will eventually make larger train tunnels underneath the water so we can travel under oceans to other continents?
I like learning about integrated circuits!
I’m looking forward to the upcoming Science Fair. The segment on the bullet train was especially fascinating. Learning that it can travel 150 feet in a single second is mind blowing. I’m excited to dive deeper and do some research on it myself. The Protègès video was, once again, both fun to watch and highly informative. Thank you , Dr. Billings, for another excellent episode of Science Live.
Dr. John, how many comets do they predict we will have this year, and is there any chance there will be one even bigger than LoveJoy and the “Doesn’t-Have-A-Cool-Name-Yet” comet?
integrated circuits are some interesting!
Loved the bullet train stuff
what do u need to make one of the circuits
Happy Inventors Day AND Happy Valentines Day!
HAPPY VALENTINES DAY!!!! I’m so grateful for science live thank you! 🙂
Hi! it’s my favorite day of the week. Science live!!
ACELLUS IS AWESOME
Dr. Tobias, the magnet train seems so, so unsafe because the wheels are not even touching the track so they could just float off the track. How will they keep the trains from doing that?
Dr. John, why is the blue tail called the plasma tail?
I love the multiplication songs!
These are awesome videos!
Really loved this Science Live!!!!
Hope y’all have a great weekend!
i love these videos so much
Love watching these lives.
in a next science live, can you explain how to build a circuit?
Bullet trains look really cool.
how bout dream for the comet
Happy Valentines day!
I want to learn more
