It is very interesting that the mimosa pudica plant take water out of its leaves!
Plants that can open their leaves now that is cool.
I learn so much for watching these!
Science live is the best!
It’s super cool that Dr. Billings created things that have lasted all these years. I’m excited to see how and if this will change in the upcoming years.
These science lives rock!!!!
Science Live is the best!
I am happy to be doing acellus
This was awesome to watch!
Always fun to tune in!!!!
hello from Minnesota
Fascinating Science Live this week! It’s nice how these can keep me focused on the learning because I have such a bad attention span.
Dr. Tobias’ part was really interesting this week
Saying hello from peru
I love Dr John. He is my favorite teacher. I miss taking the coding class with him and the little robot. The plant that Dr John talked about, we have it in our house, we call it the sensitive plant. It is awesome to learn how smart this plant is.
Hello! Checking in from Texas.
it would be great to build a robotic claw through accellus.
What do you think about global warming?
Can you have a waterproof microcontroller?
hi from Montana USA so happy to be here!!!
Science Live is great!
Does the tickle me plant grow flowers? And if so do they retract to?
Thank you again Dr. Roger Billings
What other plants fold up like the touch me not plant
Hi from NC! I wonder if I could make a hydrogen ran vehicle that would sure impress my family!
Please don’t leave Dr John, I love all the things you talk about every week. The story about the plant that closes up when you touch it is so cool! I want to find one of those plants and have it in my yard. R51 actually taught me something this week. Now, I want my lights to turn on and off when we walk in the room.
Acellus is the best!!
Being able to have an alive computer is amazing!!! We could combine AI servers with greenhouses to create more oxygen, use less electricity and water!!!
thats cool r-51
I am glad that the researchers at Washington State University did a study with Chat GPT because I have experienced this before, meaning that I will ask the same question twice and it will give me a different answer the second time. It is good to know that Chat GPT is correct 80% of the time.
back for another one!!!!!
Another amazing science live Dr. B! I cant wait for the next!
Thank you for making science live possible! see you next week
I really like math, so I am looking forward to the new math course with Patrick Mara
I love acellus my sister graduates in may!
Hi from New York!!
Hello; watching from Texas!!
hi this one was amazing i loved it so much i always look forword to these
I loved Thor’s Fortress. Very cool episode!
We enjoy these weekly videos. I find all of our family members excited to watch.
Plants are very, very interesting to me, like, what if they have a nero system that works and looks differently than animals?
The plant that reacts when you touch it is really cool.
This episode reminded me of the smart bees.
Acellus is the best!!
This science live was so funny! I loved the pig part; it has to be my favorite.
How much different is a Fish’s nervous system compared to a human’s?
Hydrogen cars are so cool!
That robot arm looks so cool.
This was an amazing science live episode! Can’t wait for the next one!
Good luck Dr. John! That’s a really cool plant! The accents are so funny 😂
Hi from Georgia! What’s your favorite plant and why?
Science lives are really interesting and I look forward to watching them every week.
the Lego part was really cool.
MEEEE, that’s so Amazing!!!!
I loved watching this live. Thank you for making these for us!!
Lego Wars haha
Science Live is so interesting!
This was a fun live.
Yay! Claudia
I was wondering if you can make a drone with the arduino.
Love this one so interesting!
What else can micro controllers be used for?
thats sooooo cool!
this has to be one of my favorite episodes yet is was cool!!!!!
Hi from Oregon!
I love the sensitive plant(Mimosa pudica)! I’ve had a few in the past and they are fascinating!
Here from NJ. Always looking forward to Wednesday.
Hello from South Carolina
Another great Science Live with a interesting lesson on the uses of hydrogen cars. And the proteges did a awesome job today, keep up the good work.
I enjoy these lives!
Happy aniversary! Loved the humor this episode!
I love science live so much it inspires me!
Love the live!
The Arduino controller was exciting. Science World sounds like fun!!
Yes! We should put an microcontroller in the Gold Store! I think it would be a fan favorite! I also enjoyed the protege’s silliness about the education level!
Hello from a small town called Anderson creek in North Carolina I would like dr. Rodger to film his own class on how to make a hydrogen car
Acellus rocks!
Microcontrollers are interesting and useful.
My mom has plants and talks to them. She tells me how they listen and can respond.
I loved the fortress building and the electronic Arm!!
Science’s live is my favorite part of my week!
I love how just one person can do so much, quite inspiring
this one was great!!! I’m looking forward for more science lives!!!
acellus is the best!
Cool how the plant close up to protect themself.
I like listening to Dr. JON
Its so cool that a plant can close up when something or someone touches it!
Seeing the 555 device was so interesting. So many ways to use it.
Another excellent science live! I adore Acellus so much!!
I would love to get an arduino board.
The hydrogen car is awesome.
I look forward to watching these Science Lives every week!
i love when caleb destroyed the houses
I would like to learn more about hydrogen.
Thank you so much for doing Science Live every week! This weeks live was awesome!
I agree with you about Chat GPT giving two different answers to the same question. We must be careful.
I can’t believe he won’t be there next week he’s one of my favorites too!!
I like all of Tobias’s accents for different countries.
Science live is so fun!
R51 making a appearance at the end was funny😂😂
hi from sunny alabama
Plants can be smart!
What an amazing Science Live!!
I love Acellus!
Yeah i would love to see a microcontroller in the Acellus store.
Hydrogen cars are really interesting.
Howdy from Texas! You should name the Arduino the Acellus board!
Those plants were so cool. I would like one as a house plant.
The Arduino is so cool to just program it and you can use.
We can’t wait to visit Acellus headquarters one day!
When can Acellus World come to Southern Nevada?
These are the best!!!!
I think the Billings Board
How long did it take to purrfect the circut board?
I didn’t know that microcontrollers can be so cool
Hi from Kentucky! It’s great to see all the inventions and episodes each week! Love science live!

I would love to check out pre-calculus on Acellus soon.
Wow, I enjoyed the science live today! Super interesting!
I think that the plant were cool😎🤔☘️🌿🌱
Great science live! Cool to hear about the new math course.
it would be awesome if we could have a microcontroller for all of acelluses students
Hello From Texas.. Love science live
that’s so cool that plants can learn
the 555 looks cool and has a big use but i thought that was funny was that the 555 looks like a giant bug shape
hydrogen house that seems cool
Hello from Texas.
WOW I can’t wait to see the first hydrogen car at Acellus World !
I love plants because some of them have colors on them.
Congratulations on 60 year anniversary of the hydrogen car😀
had a blast watching this!
Love science lives. Cant wait till next weeks.
plants do math?!
Science is super cool
I LOVE SCIENCE LIVE!!!!
I love Acellus!!
When Dr. John said ‘touch-me-nots’ I thought he was talking about a different plant. There are plants around here that when you touch their pods, they will pop and release their seeds.
I thought it was cool that they made the Arduino!
Amazing. Hello from Alabama!!! Good lesson. 👍
The building for the robotic clock was super cool!
Hi from Indiana.
hello from Virginia
Hooray for another amazing Science Live!!!! 😀

Why does chatgpt sometimes give wrong answers will it be fixed and was it just a small bug in the coding.
Yay Acellus!
This video was really fun to watch i learned so much about the circuit looking things as well as other cool things! My fav part was the building blocks with the pigs! It was so super cute! But over all this was a super funny and great video to learn from!
thanks for all the work put into these videos.
Learning about investingntioneering and microcontrollers is so interesting!
It’s so cool how he just know how to make a cool invention.
