it is very interesting that sweat can be used to detect so many things.
Science is so cool, I love science live !!
I love science live and inventioneering so much, thank you Acellus!
R-51 is my favorite!
Science is the best!
*I don’t have a question. I would just like to say lady Pajet Monet looks very beautiful in her sparkling top.
I love learning from acellus
Its getting pretty cold outside here in georgia! Hopefully we’ll get snow and I love these lives!
Science live is one of my favorite things to watch because I get to learn about new things that never came across my mind and how thay work and I find it really interesting and fascinating .
It was entertaining listening to you talk about science. Thank you!
so very interesting, one of my favorite things to do every week!!!!!
I love Science Live! It’s the part of my week I look forward to most! 🙂
I think its cool that it only took Maxwell a pencil, mathematics, and some science training to discover radio waves and that they are the same thing as light because they travel at the same speed.
Loved this live! Learning about graduating from the academy was nice to hear!
I love R51
This is very motivating and empowering to anyone who loves to learn. These videos are like building blocks for people with the creativity and drive to create things! The world needs people with diverse skills! I love this series very much!
Thanks for the great episode Acellus!
it was interesting how they made a diode that gives off infered light
Frogs are really cool
Thank you to everyone on the Science Live Team for making this livestream come together, and teach us something new! I agree that the story about L.E.D. lights was very interesting . Learning about Radio Waves is also very interesting. I hope to learn more about Radio Waves soon! Also I agree with what another student said which is Ms. Pajet looks very pretty and I also think Mr. Billings looks very nice aswell! Have a blessed day/night!
I learned from Dr. John that mold can shield astronauts from radiation. Tobias talked about the inventor of the LED light. I’m hoping that we get to see the Ventioneer’s Club in this episode. Dr. Billings is showing us an experiment in Area 51. Dr. Billings also said that Marconi was a Keystone Inventor. I am excited to hear that the kit for Dr. Billings’ experiment will be for sale in the Acellus store.
Learning about coherer was interesting, I had never heard about it before!
Learning more each week! Keep up the great work. It’s a pleasure to gain advice from a student of Thomas Edison!
My favorite part of this weeks video was when Dr. Tobia’s mentioned LED.
Science live lately has been asking a lot a questions around the use of hydrogen. The rest if the country has falling gas prices, but Washington is still really high. I wonder if hydrogen cars would help.
enjoying Acellus
Wait, so we can make a Coherer at home? Cool.
LED and infrared lights are so cool 😀
I LOVE SCIENCE LIVE!.❤️.
I really enjoy watching the Science Live videos every week because there are so many interesting things I get to learn about.
I love science! R51 is hilarious!
I want to be a Keystone Inventor someday!
Absolutely love these videos!
I really enjoy the way Dr. Tobias explains the backstory’s and ideas leading up to these amazing inventions. Makes them seem a lot more interesting and engaging.
Science is 😎.
LED lighting certainly has come a long way!
Science is so amazing! Learn something new every time! Love Acellus!
We can all aspire to be keystone inventors, I saw a lot of creativity during the t-shirt inventions
Congratulations to Jamie for graduating!
Dr Rodger Billings is a very busy man. Always inventing something.
From Ohio, this science live was very interesting and I found it fascinating.
I wonder, regarding the coherr-er, if it would be possible to spread the two tin foil taped things(or what is in its place) farther apart and still get a transmission is you had a bigger radio wave emission from the radio station/lighter/whatever you wanna use?
Doctor B is very smart!🧠
I love science live it brightens my day.
R51 is awesome!!
How does the the radio waves from the space station make its way through space? Furthermore, what does the signals bounce off of to travel to earth?
We love R-51! And Science Live!
The Coherer is so cool! It was really interesting to learn about it
I had heard about the radiation clearing mold before and it’s crazy how nature adapts for life!
Love watching science live!! I was thinking about the diet you were on a few weeks ago. How is that going? Any new updates or advice for anyone looking for a good diet?
I CAN’T wait for R-51!!!!!!!!!!!
Science is the building blocks of life
Thank you for showing the experiment with the tin foil and light bulbs.
my favorite part of science live was the breakthrough moments in science! i never knew that LEDs were created during the 50s! now i wonder how the LED evolved from the past
I love Science Live. Teaches me so much!
I love science live; it is so fastinating! I love learning about current inventions. Right now, I’m currently saving up my coins to get one of the science live shirts!
I didn’t know L-E-D standed for something.. COOL!!!
Science Live is so cool!! This week is super interesting!
I always love Tobias. The facts….. AMAZING
I think the whole process between inventing a product and marketing it is pretty cool, love learning about it through you!
How does the mold insulation effect people allergic to penicillin?
The radio wave receiver is very interesting. Since a thing was created to send radio waves and cut them already exists I think I know how it works. There is a button and as long as it’s pressed down, the light stays on because the connection has not been severed. Once it goes up, there’s probably some kind of mechanism that disturbs the balls, making the light go off. Tell me if I’m wrong!
Learning about radio waves is cool.
The LED lights were cool to learn about!
I love this lives. I love that y’all are always teaching us new things.
How was Hertz able to transmit radio waves without transistors or modern equipment?
Thank you for another amazing science live!! I love these!
I think Luke may be onto something when he asked if dark matter could be solved with math similarly to how radio waves were discovered. It’s a good question and I think it should be given attention
This is the original comment for reference:
“When you said, “Sharpen your pencils and start figuring things out”, and you spoke about the radio wave stuff, my first thought was dark matter. Now, could math be used to “solve” dark matter?”
R-51 is so funny
Science is actually really interesting!
Happy December! Can’t wait for Christmas!
Radio waves are SO fascinating!!
Thank you for your commitment to furthering our education!! As a student, I enjoy Science LIVE because I can learn new things in a way that is fun and entertaining.
MAKE A MAGIC CLASS PLEASE
I’d want to take my dog, Maverick. He is a Siberian Husky.
I really love how detailed the science teachers can be in this livestream. It’s so specific and complex, yet it’s easy to understand. This is why science, for me, is #1 all day, every day.
Really enjoyed learning about keystone inventors. Love R-51.
PAGET helped me so much with her classes can’t thank her enough. Loved learning about Morse code
R-51 is awesome!
Another amazing livestream! So grateful for this program and all the things I’m able to learn. 🥰 (Yes, I am rewatching haha!)
I am working ahead in Acellus so I can finish school early and start next year early! I love how I can work at my own pace!
Science is like MAGIC!
Science is the best, hope to be an inventor someday!!
“Sharpen your pencils and start figuring things out,” my dad says something like this all the time.
Going to Mars is out of this world! Get it! lol ok. I love science!
Dr. Billings makes science so much fun!
The many ways, we can use science is amazing.
OMG I learned so much from this. it is truly amazing keep it up.
Its interesting how mold can actually protect the astronauts in space but here it can make us sick.
Thanks you so much Dr. Roger Billings for Science Live. I like it so much , It is very cool to learn new things every episode.
Science live always brightens my week!
Thanks for the live this week! I love acellus!!
I loved how you made the invention light up with the lighter! One day I hope to invent something like Roger Billings!
I really enjoyed learning about the experiment Dr. Billings presented.
I was so excited to see Dr. B in Area 51! I also appreciate the link/encouragement to be nosey and ask questions, while giving us tools and ability to think more freely, to become a Keystone Inventioneer
With our modern rockets, how much faster could we make it to the moon than the Saturn V rocket?
Amazing live as always! Such a joy to watch!
I enjoyed learning about how all those inventors preserved with their inventions even though others said it was scientifically impossible or unlikely.
another science live of peak learning with roger billings
We all love Science Live in our house.
I enjoyed this episode and I am looking forward to the next science live. Thanks Dr. Billings
My mom is from Ukraine and she was 6 when Chernobyl happened. She told me stories and she visited the area in 2021 – its wild!
Science Live is so amazing!! I love it so much, It’s one of my favorite things every week.
It was interesting hearing about the cohere kit, sounds fun!
science is so neat!
Thank you for the tips leading up to graduation!
I love science live
is there a infrared vilot
Science Live is always teaching me new things!!!
R51 is hilarious. I love watching him.
Science Live has taught me lots of things about, hydrogen, Inventioneering, raido waves, and etc. thanks Roger billings for Science Live 🙂
Another Science Live!!! Yay!
Science is really fascinating to learn about
I never really liked science until these.
My favorite part was the about the radio waves to light the bulbs, like magic. People used to communicate through radio waves.
This was such an interesting Science Live! It is so neat to see how the frogs adapted to survive in the radioactive environment and how black mold thrived there.
The radio wave experiment was really interesting.
Science live is definitely one of the best parts of the week!
I am going to look for some of these circuit experiment kits to do with my dad. They look fun to make!
I look forward to Science Lives every week! There’s so much interesting things to learn
I love the experiment with radiowaves using the tin foil and powering the light bulbs.
How would they protect the astronauts from the negative affects of the black mold?
Science Live was so great this week! I learned so much.
I had not heard about Maxwell and Hertz before and found their stories fascinating. It’s hard to believe that Maxwell could be so accurate with his theory on radio waves just by using math.
The astronauts should bring a lot of blue cheese to absorb the radiation!

I have researched the animals of Chernobyl with my mom before. She finds it all so interesting!
I like Tobias’ section so much .
Im from Texas! So excited for science live!
I love how inventors see a problem and then set out to fix it!
I love science live, it is AMAZING!!!!
R 51 is so funny! Never fails to make me laugh!
I especially liked hearing about the history of infrared lights. I am very interested in its healing properties related to mitochondrial dysfunction.
who would have thought Mold is that useful in space and used as a barrier. LED is now the wave what is next? Amazing knowing that a spark creates a radio wave. Science is just amazing just like the guys in history
I love to watch Science Live because it is amazing.
Inventing is cool
That is really cool about radio waves and how many people built their ideas off each other.
LED lights are really cool to learn about
I love R-51 !
I look forward to Science Live every week!
Every week Science Live is amazaing.
We all love science ! Thank you!*
I was fascinated by the information about mold being used to protect astronauts in Mars. Science is awesome. Radiation is dangerous, but mold thrives in it and can hopefully be taken to outer space to be placed in the walls. My question is, though, how would that mold affect the health of the astronauts if they are surrounded by it? It’s fascinating, but I know how bad mold is for our health. I would be interested to know. It’s funny, though, that it can be your warm and fuzzy pet in Mars.
R-51 is amazing
I would love to learn more about how the key to good health can be linked to your sweat. It could be able to detect cortisol levels and eliminate blood tests in certain cases. I think I need to do some more research on this. Super cool! And we thought sweat was just gross!
Sensors to analyse our sweat and the green frogs turning black to adapt to radiation are so amazing.
I loved the lab in Area 51. It was like magic. Almost like a remote control.
We are eating healthier at my house too!
I love science live so much!
LED lights are so cool. We have LED lights on our house that change color and patterns for the holidays.
Science is so interesting to learn I love it!! Science live makes it fun to learn
Science Live is so amazing and help me lean new things.
I’m glad to know I can finish high school with Acellus
Hi from japan
It is amazing to see how radiation changed the color of frogs!
Hi from Japan!
R-51 is the best!
What invention or project that Dr. Billings has been involved in is he most proud of?
It was exciting to learn how to make your own coher, and all the people that helped make radio waves possible.
The kit is an amazing idea. Oh, and by the way your better than R. 51.
Science live is so cool and amazing! I love it so much!
Hi. I think R-51 is very hilarious!
Why did when we tap on the glass, the light turn off
I love science, i don’t know what the world will be without science .
This science live was amazing! Love R-51!!
The Science Live was interesting as always!
What is the first step a Keystone Inventor usually takes when starting a new idea?
What mindset helps someone grow into a Keystone Inventor?
I love seeing Dr B create all of his cool inventions its fun to see how they are made and work!
Yes, science is a lot like magic!
I love science expermint episodes!! these lives remind me of bill nye the science guy!!
Dr.Billings is very talented! Love science live a LOT!
Marconi beach is in Wellfleet, MA, which is on Cape Cod, where I am from. I have been to Marconi beach many times. So cool to hear Dr. Billings talking about Guglielmo Marconi.
I love Science Live!!
Dr. billings is the best!
