Always fascinating to see Dr. Billings in the lab testing experiments related to the topic.
It’s really neat to see how a coherer works. I wonder why radio waves make it conduct electricity…
how does the light light up when you have a spark that is not touching anything?
I liked when Dr. Billings was talking about radio waves because it was interesting. P.S. Merry Christmas!
I love this app it teaches me so much love Breanna. and hi r-51 I hope you can see this and you guys put so much work into this so thank you four putting so much work in it. I love Acellus so much.
I love learning about new things. Always fascinating.
I love Science live so so much!!!!!!!!!!!!!!!!!!
Loved this episode! Hello from Florida! 🙂
People are making wearable monitors that analyze your sweat. They could use it instead of blood samples.
this weeks video was great and fun. Dr johns was the best of them all
Hi from Oregon! R-51 is very silly!
Inventing something would be cool
what is a star made of?
Hello, from Arizona! It was really interesting to learn that mold would be useful for a trip to Mars!! Thank you for another inspiring episode! R-51 got a few laughs out of me;) “No, I just don’t see it!” ” I forgot to turn on my glasses!”
the radio wave to make the light bulb turn on was so cool. i didn’t know that could even work
R-51 is so funny it made me crack up
I love Science Lives!
Keep going keep the good work I love these science lives!!
I love R-51! Thanks for a great episode!!
thank you for creating Acellus
how would analiysis of somebody’s sweat help their health?
It’s so interesting how mold thrives! I never would have thought it was a possibility for an organism to extract energy from radiation, nonetheless be even more efficient that way.
R-51 is funny😃
Learning about the radio waves was very interesting it’s cool that it can travel across the ocean.
I watched a documentary about cherynobyl with my parents. It talked about the frogs changing color to black to be able to stay there. It was super cool
Science is amazing!
I ❤️science
R-51 is my favorite part of science live : )
Nothing better than watching Science Live after a day of school. I love how R-51 always talks like he’s better than Dr. Billings!
I really liked this science live! I was especially interested by the tips on how to finish this school year. I will keep them in mind to finish efficiently
Love to learn new things every week!! R-51 gets me every time lol 🙂
I love the Acellus store!
I love science live 💖
I love the part on mold and how it stops radiation. Really interesting
Learning on science live makes me feel like I could do anything. It’s so educational and I feel like I learned something new every time I watch it.
Hydrogen is magical!!!
That is so awesome!
Science live is so fun!
It’s crazy that when Dr.Roger billing did the experiment with the cup and foil that when he pulled the trigger the light came on without even touching the foil or cup.
Happy Holidays from NC ❤️!
Happy Holidays from NC!❤️
I like the kit thats going to be added. I love seeing things added into the Acellus store.
I enjoyed learning about the radio wave making the lightbulb light up!
Thanks for another inspiring episode!!!
just like magic
It was neat to learn about how the frogs were different colors due to the high levels of radiation and how their melanin impacted their skin for adaptation!
Science live is awesome!
I find the gizmo you made pretty cool.
I love to learn about these new thing!
The experiment was awesome!
I loved the experiment in this episode!
I liked the story with Dr. John
Great video! I always learn a ton of new and interesting things, and it really inspires me, thank you.
Hi from costa rica.
I really like the part about the radio wave making the lightbulb light up was amazing.
I absolutely loved learning about the keystone inventor. I too hope to be an inventor someday.
R-51 is super funny hi from TX
Wow! This really proves that anything is possible!!
I am interested in building one of those coherers:)
I love R 51! Lol!!
Have you done or are you doing a study to show how well the catalytic diet works with certain types of people?
I love Dr.B he’s the best
I agree on the agreeing respectfully even if you don’t agree with their statement. You should always be respectful to someone else opinion! These lives inspire me so much! I also think it would be the perfect idea to add kits and have a good selection of kits!
Can you do collage in Acellus?
What an absolutely incredible display of the magic of radio waves. Truly magical.
R-51 always being extra lol.
I always enjoy the experiment parts of science live. This was cool.
I liked watching Dr.Billings experiment.
I really enjoyed hearing about Clerk Maxwell and the LED lights!
r51 is the best keystone inventor!
I loved the section about engineering. I’d like to be an engineer when I grow up
its cool that if it works, they could track health and or health conditions through sweat
i like science! my second live and i think its cool!
I’m so excited for the kit!!!!
Who inspired you to become a scientist?
Comment
R-51 is the highlight of my day!!
Thank you for teaching us about different inventions. It was cool to see the coherer and how it works. How electricity passes through the radio wave. Very nice.
I would love to be able to get tested with the sensors by my sweat because I hate having my blood drawn. They always have a hard time finding my veins.
Always liked learning new ways to invent something.
Science live was cool especially R-51 he was super funny.
How long does the process take for you to turn in a patent,
and then how long does it take for it to get accepted?
How do you think wearable biosensors that analyse sweat—like those microfluidic cortisol-tracking devices—could change everyday healthcare?
besttttttttttt dayyyyyyy of the weeeeeek
Are there any other ways we can use mold in space?
Great video, r-51 is always so fun to watch! Incredibly interesting hearing about the radio waves.
Thank you for the advice about how to finish my courses to complete my goal for this year.
My name is Landen. I’m from Texas. I loved the graduation story because I’m going to graduate soon!
What was your inspiration you had for the first invention you made? And how old were you when you patented your first invention?
could you do this if you had a bigger cup and a smaller tin foil and less tin foil balls.
I love how Science Live is interesting for all audiences, also love you Pajet!
The way you talk about inventing is so cool!
I think the coherer is interesting.
Science live is the best!
What has been your most challenging invention so far, and how did you overcome it?
the radio wave making the lightbulb light up is awesome!
Great video today, loved learning about keystone inventors and their inventions.
Hi, thanks for another episode of Science Live. I learned the history of LEDs and radio waves, and I like the amazing experiment. Much appreciated!
What new creation will R-51 “invent” next?
its really mind blowing how theses things work
It’s interesting how a spark produces radio waves!
I love the technology spotlight with doctor John
Thank you for this Science episode! It was very interesting to find out how can mold protect astronauts from radiation and how the coherer works. Excellent experiment Dr.B! Can’t wait to see more previous episodes!
I love Roger billings! And all the cool stuff we get to learn every week
Never knew sweat could be used to monitor your vital signs. Very interesting!
I thought that the coherer was interesting
I love R-51! He is so fun to watch!
Dr John’s technology lessons are fun
Thats amazing how the frogs adapted to the nuclear area.
I liked the beginning where it was mentioned that maybe someday labs can be done with sweat instead of getting your blood drawn.
I love inventions! Thank you inventors.
r51 is a copycat!
As a high schooler I appreciate the graduation tips so much! Please do more clips like that if you could!!!
is there going to be a seince live for christmas that would be soo fun
Hello from wisconsin!!! Love to tune in every week!
Me and my family learn so much from the science videos
Thanks for the motivation!!
this science live was fun!!!!!!!!!!! looking forward to more of them
That story about the mold was very interesting and how the frogs survived the radiation and adaptived and turned black that was so cool I didn’t know frogs could be so interesting lol
I didn’t know a spark made a radio wave.
I think that r51 is a genius
That was so cool!!!!😎
Learning about the coherer is so interesting!
Great studying tips, thank you!
R-51 was so hilarious!!
That’s crazy how frogs do BETTER in radiation! At my old school I did a paper about the Chernobyl accident and I never knew about the frogs!
I love learning about the new topics each week.
It always puts a smile on my face when R51 comes on the screen.
Morse code is neat I need to learn more!
Why did they make those aluminum balls?
That experiment was really cool! I can’t wait for it to be in the stores!
I loved this so much and I can’t wait for the kit!
Interesting how the radio waves make the light bulb light up. Love science live from TN!
Me and my family have always thought negative about mold, think again. And it is so cool because it is the holidays, so Light Emitting Diodes (aka Christmas lights) are all over the place! And I have always looked at and been curious about the Light Emitting Diodes inside of TV remotes. This episode is helpful about our life, thanks!
How long does it take for radiation to go away?
Hi from Georgia…amazing how sweat can indicate health issues. Very cool.
I enjoyed learning about radio waves. These science lives really teach me something new every time!
My first science live! It was very entertaining and informational, looking forward to more and the kit!
Eating healthy is good for you! Way to go!
It was very nice to see Dr. B in R51 Lab
I 💕science live because it is so important science is the best
I just looked at some of your new shirts in the shop and they are so funny!
Very interested in this good job Dr.B!
A lot of inventors are seen as crazy until they invent something really cool.
I am sooo exited to invent something! Thank you Dr. Roger Billings I have learned so much!
That is amazing how with that lighter you can create a spark and it causes a a radio wave that then causes that little light to turn on. This reminds me of a magic wand from Harry Potter. How do you make a radio wave travel long distance?
R51 was so funny haha
Absolutely loved this lesson so much, felt like I learned so many new things.
The radio waves are so fascinating! Also love R-51!
My little sister has Cystic Fibrosis and they found it in her new born screening and they tested my little brother for it by testing his sweat. I thought that was pretty neat.
How does a light work? How can you just start a fire without an ignitor? How does the light happen?
The science live was great and r-51 always thinks he invented everything, but I’m wondering, is it possible to make a hydrogen powered helicopter?
I always love learning about science all the time. I love learning about the technology spotlight with robots and more modern things!
Science is just like magic! That is a great way to describe it!
I loved learning about radio waves
I like how the frogs radiation change from green to black. AVAROSE
I can’t wait for the new kit to come!
i Always love to see R-51 at the end of each of these videos
First time here. Watching from Belgium. Loved this episode, so interesting. *
Hey, Acellus, can we have more science lives talking about space?
I didn’t know mold likes radiation.
I really like how every science live roger billings always has a cool science gadget to show us
i loveeeeee acellus sooo much 🙂
I didn’t know they thought LED would be impossible
Science LIVE IS THE BEST!!!!!!
I am excited for the kit to release in the Acellus store! I have to earn a ton of gold coins!
This is very cool cant wait to see what’s next!!
R-51 is funny, he’s my fav part!
Radio waves are such an interesting concept. It really shows you how such a, seemingly, insignificant discovery can really change the way that inventors can respond to differing communication scenarios.
Very interesting, though I don’t think I would keep mold as a pet
I loved this science live! Watching from Alabama!
if there is radeation in space then what hapens to astronots
Can’t wait to see the kit on Acellus shop!!
The aluminium ball thing is pretty neat.
This was the first lesson I’ve watched on Acellus. I thought it was very informative. I liked learning about how radio waves worked.
Hello from Kentucky 😀
