Do you believe the predictions of the asteroid that is orbiting the earth will eventually actually come into the atmosphere?
Like the singing dancing robot
The hydrophobic metal was very interesting
Now that was a very cool transition haha!*
I really enjoyed this and I learned a lot!
Another great Science Live! Have an amazing Wednesday, everyone!
3D printers are gonna be used for making Acellus items?
Science live is Awesome!!!*
Why dose water spiders have to have such thin lines.
Loved this live! See yall next Wednesday!
Amazing sicence live as always!!!
Hi from Florida!
I’m so happy that i learned something else today!!!
This episode was so good! Hope to see more of it.

Today’s Science Live was FaNtAsTiC! My favorite part was learning about the history of the prism and the colors.
Thank you for explaining how infrared was discovered
Hey from Taxes.
Such a cool live
Love love love this
Its so crazy that binary code plays a big part in computers!
I am so sad that I can’t go to the science fair 😭 but my friends are going so I will have them to tell me about it later.🙂
Thank you so much for this cool live. Me and my dad said we are 555’s.
I like the Flip Flop thing its a fun name but accurate name! ps: Flip Flop Reminds me of the flip flop sandle
Can’t wait to hear more!
Science is my favorite subject!!
I liked learning about the flip flop switch
The circuits in this live were very easy to undertstand.
Another good live, keep it up
this was very amazing and im so glad i was able to be taught about the light and the temp!!
It is crazy to think that all of these circuits are relatively new inventions.
Thank you! My favorite part was the light—infrared to ultraviolet.
The light prism part and the robot were cool!
Always a great live!!
Social Emotion is one of my favorite classes!! And infrared is definitely my new favorite color. Great live!

I love people who also love learning and it’s so much fun tuning into this
I AM A 555 FAN NOW. LOL
will their be any advancd art classes?
Hello from Iowa
How can you make a robot?
Loved learning about the circuits and as always the crew and whole episode was amazing, from start to finish. I’ve never seen a dull episode, all of the energy from everyone on set and on camera is always so fun. I cannot wait till next week, all of yall have a fantastic weekend!
This was a really enjoyable episode. It was great how interactive the whole thing felt!
love seeing the proteges always !!
also Dr. Tobias saying “The year of February 🤪” lol 🙂
that was cool its why i like watching
So Awesome! I love it!!!
R51is funny 😆
So entertaining!!!
That AC-D2 is bigger than mine and I cant wait to see the bigger AC-D2. And that r-51 was so funny with the teacher serum.
I’m a flip flop 🙂
I’m traveling and I’m so grateful that I can do my work and still travel.
Nice live! I am learning many different things with Acellus.
How do the gold credits work and how do you get them?
Well that was cool you guys just made me more science loving.
I cant wait for the next live! I love science.
the flip flop was so cool and the 7 thing and that blow my mind.
Can I get some of that water?
Very interesting video and see you next week.
So cool this live was super interesting! See ya’ll next week.
Hi from Jersey!
I really enjoyed learning about circuits today.
Comment hi from tn
Hi from NC
I enjoyed seeing the new AC-D2 robot and i am excited to see the one at Acellus world!
I love science live.
I love the robot!
Infared is definitely the best color.
Good scince live loved it!!!!!!
I enjoyed the video
very fun and cool live!
Cool episode.
I loved today’s episode!
I really liked the Breakthroughs in Science section about how infrared was discovered. I thought the Roger Billings part about ACD2 was cool.
I’m so glad to be in this school! That was a cool experience
I really enjoyed the sing and dancing robot that was funny!
My older brother is an Electrical Engineer, I think he might’ve skipped the Social and emotional classes. Can Pajet Monet help him?
Hi from Montana, i liked science live very much today, thank you Dr Rodger Billings!
I love science , hi from New York!!
So many circuits.
I love Science Live!
I thought learning about how binary code works was cool.

I found Dr. Tobias’ talk very interesting.
Sience live is cool especially the protoges they are really cool.
Love seeing how circuits work!! Very interesting!
Bro, I LOVE DAVID AND CALEB!!!!!!!!!!!!!!11
Wow, r51! You are so smart!
The young girl at the beginning was inspiring!
I really liked the part where the robot was dancing. Also the science behind the chips was interesting but a little confusing.
hi this is ethan from flordia
How are computer chips made?
Hi I’m Keegan, I’m from Montana and I was curious if the are different types of electric circuits for everything?
Great video! Can’t wait for next week.
It was cool about the infrared.
really enjoyed this episode! really thought it was cool watching metal float
how many type of integrated curcuit chips are there
The David and Caleb show is so fun to watch.
My question is are also aloud to make a project off a project that’s close to ours.
Great show this week, im 555
The decade counter counts 1-9, and a capacitor discharges all its energy once fully charged.
so cool learning about integrated circuits and transistors to make a type if cirtuit that the protégés made today.
The robot part was my favorite! It was very funny.
Wow I enjoyed today’s science live p!
Love the new robot. We have the small guy and love him.
I learned that an intagrated small circuit is a circuit that has really tiny transistors in it
The robot dancing was soooo cool!
I loved listening to the protégés !
I really enjoyed seeing how the robot danced. Very interesting how it was programmed to do that.
I love science live. It’s so fun to watch.
Really cool, I like the robot!
It was very cool to learn about binary and coding.
I learned about water spiders.
i loved everything about this
I loved the floating metal it’s so interesting
We liked learning about IR Light and how it was discovered.
Hello from nc
Such a good Science Live!
Hi from Texas!!
Another great episode of Science Live. I hope the protégés continue to be a part of Science Live even after this journey concludes and we learn all about computers.
I think that it really cool that an object that small can have such a big purpose.
Hello from Mississippi
The hydrophobic aluminum pipe Dr. John talked about will have amazing applications in aquatic industries!
I loved the giant ACD2, it was so adorable! Greetings from Florida 🙂
Hi from Nebraska
Hi from Chicago
I agree with Isabella yall guys rock

I loved learning how Pajet became our Social Emotional Teacher!
I enjoyed today’s program.
Hi from Tennessee
This was so fun
Flip Flop.
Great live tonight, I love seeing the amazing things our classmates are doing.
So cool, what an awesome science live
is it possible for the hydrophobic to get wet at all?
I love science lives!!!
Can this hydrophobic technology be strong enough to hold up a houseboat or something like it?
Very interesting on how they make objects float on water and repel it.
Dr. Billings is so impressive. I wonder what his IQ is.
This science live tech’s me new stuff every time I’m so grateful for science live.
I absolutely love it when people talk about prisms, because they are just so cool! Fun fact, I’ve actually gotten to hold a prism before and attempt to reflect light through it for one of my science classes back in public middle school. Which was fun, however it would’ve been better if we had windows in the classroom so we could use actual sunlight for the experiment, but I mean who can complain, that’s just how public schools are. Congratulations to Claudia on becoming an inventeneer! Good Science Live, see you next week!
this was a good episode, can’t wait until the next one!
Great show!!
hiii from tx!!!
Hello from Las Vegas. I thought the water spider that Dr.John talked about was actually pretty inspiring especially because this spider spends its whole life underwater without any gills. It breathes underwater by making a floor like structure out of its web and trapping a water bubble under it. This water spider is also able to hold water on its body by using its hydrophobic hairs that also help him breathe underwater. I think it’s cool how researchers realized that they can make metal that would not sink with this hydrophobic idea but they took theirs to another level and make it an extra hydrophobic material that actually floats.
I never thought I’d learn binary, but now that I’ve seen 1-9, it doesn’t look that bad! Though that may be because all the 1’s and 0’s aren’t in a row… .^.”
Loved the robot’s cute little dance!
Hello from Edisto Island, SC
Great show this evening!!
Thanks for the episodes of science Live! I really enjoy watching science Live!!!! 😀 GoodNight Everyone!! 😀 😀
The robot is so funny! I will save coins to buy it now.
FLIIIP FLOOOP LOL.
It’s really neat how glass can block out certain types of light even though glass is clear.
my dad likes the 555 and i like this episode
Loved that transition, super cool XDDD
This live was so interesting
