The gallium spoon was amazing!
Science Live is the BEST! I love watching it! It gives me cool facts that I didn’t know about! Who agrees with me?
I loved when Tobias talked about the movie theater sounds!!!😄
Hello from Minnesota!! watching the wild west math segment was cool!
I really enjoyed the science live today. Tuning in from France!
Us Texans loved that protege showdown!
I love learning with Acellus. It’s helped for over a year, thank you, Acellus.
I love watching r-51 he is always so cool 😎. Love r51.
These videos are pure gold!
This Scienece Live was amazing,watching from alaska
cool!!!! now I’m wondering if there will be a kit or something similar to build those kind of circuits????
The potentiometer skit is genius 😂
The fact that the brain can correct messed-uped view is amazing!
I like to divide by 2, because that is a way you can share with a friend. I think r-51’s potential is 100% for sure.
Science Live is the best!
I love learning from Dr. Billings
Science Live was amazing!!! Watching here from Missouri
I thought it was cool that your ears can turn things down.
The story of the severed optic nerve is mind blowing.
When and where is the Acellus graduation ceremony?
In this case, can flip-flops divide by three or other numbers properly? I think it would be possible to force a reset with a certain combination, which would require a few of the flip-flops.
I ❤️ Science Live!!!
howdy from texas ! yeehaw !
I always love watching R51, he is hilarious!
hello from Alabama. loved the wild west math battle so funny
That’s so cool how you can divide with a circuit board!
The rockets are incredible – and I love that you mention actual students!
I like R 51, he is so funny!
2 is my favorite number R51 howdy from Oklahoma.
Our horses ears move to, when ever we are riding in the mountains or anywhere we watch if they hear anything cause they can alert us if there is someone coming from the trail or animal near us.
you some how make each episode better each time!
See I think its really interesting that the new rockets are smaller but more powerful and I’m wondering if a hydrogen powdered rocket can be real thing?
Omg it was hilarious. It was so funny and I actually learned a lot.
I liked when they did the cowboy scene, it was so cool! I love science live so much that I would love to learn more about IC – Divide by 3. I love you Dr. Roger Billings! I can’t wait to learn more about technology. Caleb and David are the one that can know how to be the ones that can make us laugh all the time when we watch science live.
Jackson from Louisiana and I love Acellus learning. Its so much fun.
Gallium is such a fun property! Its amazing how it looks like Mercury but It’s not.
I enjoyed how Dr. Joshua talked about the three steps of how to plan your graduation and goals after high school. I will definitely keep this in mind.
Science Live teaches me so many new things!
Thank you Acellus team! Learning about the ICs was so interesting, is that how calculators work?
As someone who has lost people to cancer I think its absolutely amazing that they are working to find a cure!
The Protégés were amazing 🤩!
Why is everyone so nice in Acellus.
The projection and movement of sound is really cool.
Hearing how intricately stereos are made makes me appreciate them so much more than I already do.
That’s awesome how they are treating cancer cells with special bacteria. I do remember hearing that Covid-19 is a human made virus so it is possible to make special bacteria like that. About gallium, you also can’t spill it on computers and phones because it can damage your device. The same thing applies to soda cans. I remember watching the good morning part from singing in the rain. Maybe I might watch Fantasia since I have Disney+. Did they find the hacker who did that? Wow!! they used a big rocket ship to get to the moon. I feel bad for R51 because he missed the scanner calling him a socional super star.
I wonder how long the Honors path is compared to the Standard path.
I had no idea that modern rocket ships can be reused!
Wow the human brain truly is one of the most complex organs in the body.
My great grandparents have a record player and some records. I just recently saw a cassette tape for the first time. Things have come a long way!
I LOVE Science Live!!!!!
Never fails to make me laugh!!! The math battle skit was too funny!!!
Love science live!! keep up the Great work you guys! This will never get old. I can’t wait for the next one, literally the highlight of my day!! (insert little dance)
Gotta love the Protégés and the Inventioneers, but I also enjoyed Tobias’ talk about stereo.
Thank you Dr. Billings for teaching us again.
How do you guys always learn so many things to teach us in just one week?!
New to Acellus Academy and my first time to watch Science Live. I love it!
The gallium spoon was very interesting
I like the new girl.
I have trouble saying potentiometer, just like R51
Science lives are a great way to learn interesting facts. Thank you for the hard work you guys put into them!
cowboy scene hilarious!!🤣
I love these episodes!! Thank you so much Acellus team for making it happen! Here from Connecticut!
Howdy, Acellus! I think this is my favorite episode of Science Live yet! Welcome, Claudia!!!
An IC Divide by 3 is an integrated circuit that reduces an input frequency to one-third of its original value. It is commonly used in digital electronics and timing applications where specific frequency control is needed, and of course the secret weapon was a girl. (in the cowboy scene on of the cowboys did the 67 hand gesture when the numbers six and seven were on the screen which was really funny)
Alan Blumlein’s story was so cool! learning about how he incorporated psychology to make his stereo sound was really interesting. We got introduced to the new inventioneer Claudia! She already seems pretty cool and I loved the whole cowboy segment in general it was so funny.
i love acellus lives!
I thought the binary decade counters were so cool to learn about because im super into computers
This science live was so captivating!

Hi from Texas!
Hi from CA!
I and my family really enjoyed the show today! The bacteria eating cancer is really interesting! My grandfather passed away from cancer and my grandmother has had cancer twice so it really hits home. Dr. Billings – Area 51 makes me laugh. I love that you’re so fun.
