If the mold works well in shielding radiation, can it be used in nuclear power plants? There are different types of mold so does all mold do this or only the black mold? Is it safe for humans with a mold allergy?
I just told my siblings I would name my mold bob haha
Mold for a pet?? lol not for me
I found it interesting on how the “Light-Emitting Diode” came to be!
Thanks for teaching some more awesome stuff on inventing! I look forward to this every week.
R-51 is so funny I would like to meet him one day in my lifetime!
The background of LED lights was very interesting to hear about
Science Live is really inspiring!
tobias’s stuff is always awesome
I thought tobias talking about the led was cool
So glad to have started and learning through Acellus. Best decision made for education.
I’m new to Acellus, I just started yesterday, and I’m already loving Science Live. This stuff is crazy!
That experiment was cool 😎!!!!!!’!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Dr. Tobias speaking about LED’s was very interesting and entertaining.
I look forward to these every week! Awesome live today 😀
R-51 is really funny! I really enjoy watching science live!
I like your tie.
R-51 is FUNNYYYYYY
I love listening to science live! It’s so fascinating to listen to all the science and inventions.
It was interesting that Maxwell predicted radio waves without testing.
Science is magic!
Dr. Billings, I like the way you question things. I need to do more of that!
I really enjoyed this.
Cool video, I really liked learning about how LEDs were made, since I have a lot of them around my house, they’re awesome!
I love Acellus
Hey, what makes the mold grow better in radiation than in normal conditions? What is the science behind that?
Science Live is so Awesome! I love it!
I love to see the new things added to the store. I’m sure it motivates many people even more.
I love Science Live!!
Love Wednesdays nights.
Can’t wait to see how they made the light turn off!
Science live is so cool and R-51 is so funny I cant with him
Love R-51
R51 is actually so funny his bits always make me laugh, he really should have his own class.
I love science live!
This was a great Science Live!
I really like when Dr. Roger has the cup with the aluminum foil balls and he has this slider and he has the lighter really close to the LED light and he hits the button on the lighter and he holds the lighter near to the LED light and when he has that light or near the cup, but not touching it, he hits the button and the LED light comes on.
I honestly thought that radiation would kill anything in its path if your close enough to it. It amazing how something like mold is able to even eat radiation without the effects by it and helping animals and even humans by pass such major obstacles. Most people would consider it a pest in their homes but managing to be a great discovery for astronomy!
HAHAHAHAHAHAAAAA R51 is sooooooooo funny!! This is me when I see him.🤣😂😅😂🤣😂😅🤣 And this is him.🥸🤓🫨🤪
Why did the nuclear power plant blow up.
I think that Dr John is very intelligent person and I love hearing him talk about innovations in science, he should make a class about all the things he talks about on science live in addition to his coding classes.
I loved this! Thank you!!
Enjoyed the live and love R-51
Another good one
I love Acellus!!!!
Monet eyes are pretty
HELLO from Illinois!!! I love Tobias’s parts every time!
One day I want to invent something!!
R 51 is crazy! he made me laugh so loud Mom was like what is it and I had to tell her what R 51 did
I love watching science live and learning on Acellus!
How big of the margin of error be on the sweat sensor test compared to a blood test?
I’m looking forward to the kit in the Acellus Store. That’d be a fun experiment to do with Christmas lights.
Science live is so awesome!
I love R-51!
Great introduction to inventioneering — clear, creative, and engaging.
It is so cool that by pointing a remote and clicking a button, things turn on…
The information on black mold was so interesting! I didn’t think mold was good for anything.
i love R-51!
this lesson was pretty awesome
Science Live is very fascinating.
This science live was really interesting
The coherer is an interesting contraption
Love the experiment.
My favorite part of my week
I loved the R-51 it was the most hilarious part of the show!
That is so cool when the frog is different colors
I would love it if you put new things in Acellus store!
I love that science live has such interesting and engaging facts!
I liked learning about the light and radio waves! If there were invention kits to do at home, like a science lab, that would be fun!
I’ve never had so much fun learning science
Gotta love R-51 hes so funny!
i love Acellus.
Would using sweat to tell you about your health be more effective than blood?
Mr. Billings in Area 51!🙀
That was a good experiment! I would love to do that experiment at home!
Interesting how mold get energy from radiation. Science live is awesome!
The theory of radio waves being purely done with calculations on paper is a really cool fact.
Do you think you could talk about nuclear power I’m studying to be a nuclear engineer and would love to see your thoughts on nuclear power as a whole.
Could Chernobyl become cleaned up and eventually be put into use again?
Science Live Rocks !
Watching from the Virgin Islands.
inventioneering is so awesome!
Interesting how moles get energy from radiation. Science live is awesome!
I never knew how LED lights were made! So cool!
The science news is always so exiting to hear! Thank you Acellus for keeping us all updated on things!!! :]
I love these videos because they teach about interesting topics in entertaining ways.
How long does it take for a frog to learn to adapt to the explosion?
I love r51! The science live was great today!
Cant wait to check that kit out!!
Id name pet mold grubby.
I really enjoyed this!
Even when it’s off, a radio keeps conducting? That is awesome!
I liked the part about magic is like science
This was a very entertaining live! Greetings from Chicago, Illinois.
I learned about Morse code and how it used radio waves i thought it was cool!
Always enjoy watching these!
Liked the radio wave experiment
I always enjoy watching these science live. I always learn something new
This was an amazing project!
Hello! Like the joke about the kids meal lol
Noah. C how does the spark light the light bulb when there is no spark, at least i don’t think, i just don’t see it.
Here from Texas..science live was great!
You guys should expand the Acellus gold store/ wallpapers!
This live was great! The idea of having mold as a pet is fascinating (and quite amusing)
I never new that lighters could be make radio waves, science really is like magic!
happy hollidays
R-51 is soo funny!!
Well-done Science Live!!! <3
Any news about the hydrogen?
How do you create infrared light?
How did all that damage happen to that radiation place
I loved when Dr. John talked about the radiation with the frogs! Also so cool how mold is better to take to mars! lol
R-51 is hilarious!
R-51 is hilarious!
I found it interesting how in the “Technology Spotlight” despite Chernobyl being a highly radioactive place even today, life could still find a way to survive the harsh conditions and how this could be useful for us humans as well.
I don’t think my mom would like it if I had mold for a pet!
Science Live is so Awesome!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Never knew that mold is able to protect against radiation!
I am excited to see Dr Billings next invention.
Tuning in from Billings Montana
Did you know at the same nuclear power plant where the moss grows there is something called the Elephant’s Foot.
Science Live is cool!!
Happy holidays everyone! I wish you all good luck in your various fields of study.
Hello from IL! I think we should add more activities.
Time to learn something new!!!
R-51 is cool!
*I liked Dr Joshuas part about acellus.
GOT TO LOVE R51
Hello, from Long Beach, this video was actually pretty cool. 👍
Mold as a pet, my mom would not be happy about that.
how can he turn on a light with just a lighter
thanks for the great lesson today
i love when these come on! its so fun to listen to.
love R-51!
I love Science Live!!
I love learning about NASA
How is mold considered a living thing?
I love these so much!
Happy fall drB.
Dr. Billings is a modern hero that fuels my dream of becoming an inventor.
I loved the joke about the mold. That was funny.
Hi Addison from Guam 🇬🇺,I am so happy that I’m i Acellus.
I love science live and I know it would be cool if there was a science live backpack or fidget spinner!
When will Todd Edmond’s new class be available??
I love r51 he is so goofy Its my favorite part of science live
I think science live is a lot of fun and I cant wait to see all of my teachers when I graduate and science live is so awesome and interesting
Great episode! The Keystone Inventor topic was explained so clearly.
R-51 is cool!
I inspire that one day I may follow in the footsteps of Dr. Billings and achieve becoming a Key stone Inventor.
This edition of Science Live was fascinating! Learning about Maxwells genius invention inspired me to try something new, and I can’t wait to see a new exciting addition to the shop. Keep up the amazing work.
Learning about the radio waves was REALLY interesting! And I am also excited to see how the new kit will look!!!
How can sweat from the body do that?
Tuning in from Sioux Falls!
This was awesome!! I love R-51!!
Ezekiel it would be nice to be able to wear a device to check levels inside our bodies without having to draw blood. I am not a fan of getting my blood drawn.
R51 is one of the best parts of Science Live!
If you could just invent something with your mind and have it pop up , what would it be?
Science Live was awesome! I learned new things and it was really fun!
I agree with sophia in the comments…..A kit in the acellus store would be amazing. Thank you for offering us science live to help offset our tuition. My parents wouldn’t have the budget without the science live. Thank you for being so amazing for us.
I look forward to Dr. Billings each week. He is so amazing to me.
What does that mean for people with allergies to mold? Do you think they will ever be able to go to Mars with their allergies?
Putting mould on a spacecraft for protection is a really interesting idea!
Hi from Arizona, this video was really cool
Roger billings is interesting, along with his invention of the hydrogen car.
Can’t wait to live in our hydrogen mold spaceships on Mars
Science live would never be the same without r-51.
Crazy how an inventions can start off be for one thing then changed to be used for something else.
This has been one of my favorite lives so far, I’m excited for next week! And I hope we’ll be able to get an acellus course on morse code.
i love learning about science , and im so thankful for Acellus
Is hydrogen cheaper than regular gas
Science live is the best!!
R51 always makes these so fun to watch.
i would really like to try that light experiment
I think this science live was awesome!
What is another way to create a spark if you did not have a lighter? Is their something else similar or more basic that would be just as effective?
I hope the Acellus team had a Happy Thanksgiving, and I hope you all have a great Christmas as well!
It is very interesting that sweat can be used to detect so many things.
im looking forward to getting my kit in the Acellus store.
