Will it still work if you put water in the cup
science live is amazing, I really loved the part about the tree frogs. we have tree frogs down in Louisiana and last year we found some with oak tree patterns they were amazing!!
I always thought that going to Mars would be super cool, and the fact that we have discovered a possible way to protect astronauts from the radiation of Mars makes me super happy and excited for what could be instore for us! Thanks Dr. John!
I was wondering, when did Acellus start? Hi from Texas!🤠⭐️🇨🇱🌵
Hello From New York
Science is so fun!
How many different LED lights are there? Are they used more than flashlights or vehicle lights?
I 🩷 science live!!!
i thought the radio wave part was cool
I love Acellus.
This lesson was so cool!!
The talk about mold blocking radiation because it absorbs it was really interesting.
Wow! 😎😎
I love to learn science from Dr. Bilings! I always fee smarter after these lives.
Hi from Arizona!!
Can’t wait for something new in the Acellus store!
Great Science Live! I was wondering, why doesn’t the electricity travel through the little foil balls to the other side of the clamps? Why does it need radio waves to travel?
This episode was super interesting the tin foil cup experiment blew my mind. 😱😱
I enjoy your videos and learn so much from them
I love how you make science so much fun!
You always surprise us with something new. I love seeing how inventions work.
science live is so awesome DR B
Cool to see how these things work!!
My brother and me love Acellus so much we get to spend more time together
That’s pretty cool doctor B.
I didn’t know that there was radiation in space mostly because I thought that there was nothing in space. And how a certain kind of mold can someday literally protect astronauts in space.
you should patent the word inventioneering
R-51 is soooooo funny!!!
Science Live is so cool!
It is always fun to watch each new episode and learn some new things I would love to invent something amazing one day!
Thank you so much acellus i love theses videos
I love this! R-15 is hilarious!!
I can’t believe you are making us wait an entire week to see how they break the radio wave!!!
That was an amazing episode. I have a request for Dr. Tobias to cover, the invention of duke tape. People don’t realize how important duke tape is the people who protect us and use in everyday life.📦✂️
Merry Christmas!🎄
I like being able to see the other kids on here too. That’s so awesome!
Great science live! I find radio signals really interesting.
This is so exhilarating R-51 is amazing I love learning new wonderful topics each episode is something new !
Absolute Cinema🙌
I like the frogs
Maxwell was my favorite inventor for inventing LED light bulbs.
The coherer is so cool! Thanks for the lesson.
I love science live it was so interesting to watch you turn on the light without a switch and see that mold grows faster in some areas.
Science Live is awesome!
I’m so excited that you are going to put a kit in the shop
I love Acellus!!
R-51 was really funny!
That’s really interesting that NASA might experiment with mold since there is so much radiation in space.
R-51 is funny!
I love science live!!! ❤️
Fun fact: Overview
Black mold can grow faster in high radiation areas because it uses a pigment called melanin to convert ionizing radiation into energy through a process called radiosynthesis. This process, which is similar to photosynthesis in plants, allows the fungus to use radiation as a food source, causing it to thrive where other organisms would be harmed or die.
Researchers at the University of Sydney, Australia believe the key to healthcare may be hidden in your sweat. They are currently testing wearable micro-fluid devices that analyze your sweat, and can track things such as your cortisol levels, along with removing the need for blood in some medical tests.
Who invented infer-red?
Thank you all for continuing the invention series I really enjoyed it.
Considering how they used the mold to protect against radiation in space, I wonder if they could use it to make jobs at nuclear power plants even safer.
That kids meal joke is hilarious
That was so funny Mr. b and awesome thanks a lot.
How can they tell different things about our body through analyzing our sweat?
It’s so amazing to see how this works! I ‘m so excited that you’re going to be putting a kit in the store! Thanks Dr. B!
Is aluminum the only metal that can detect sound waves?
That’s cool you are going to put a kit in the store!
I never knew Dr.billings had the idea for the first hydrogen car!
Molds reactions to radiation and the rapid growth it experiences is interesting. I enjoyed this discussion during the tech talk. The discussion of the radio was also excellent. Great science live, keep up the good work!
Knowledge and learning new things is the best tool for your brain!
your my favourite teacher pajet
Thats so crazy Dr. Billings had the idea to invent the first hydrogen car when he was only in high school!
I learned so much today!! Love tuning in to these lives. Even if I’m a little late..
it’s cool that mold can protect from radiation
Would people be able to adapt to radiation like the frogs?
I love R-51!!!!!
I wanna be a scientist when I’m older
I love r-51
I LOVE THIS!!!!
I love learning new things about science with Tobias
How has the coherer helped shape technology today? In what ways do we use the ideas of these inventions in everyday life?
Super, super cool!!!! Will definitely be saving up to get the kit from the acellus store!!
I liked watching the light come on with the lighter. It was cool.S
That so awesome you’re going to put a kit in the Acellus store! That so awesome Dr.B!
I found it interesting that James Clark Maxwell was the first person to theorize that radio waves were a real thing.
R-51 is sooooooooooooooooooooooo funny!
Love it. 😇😍🤪😂
Cool to see how these things work!!
New episode every Wednesday, 7:00 (PM).
This was so cool
I love to learn about new things
Hi from Georgia!!
Live ❤️science live 😀😀
FROM GEORGIA 🫡
r-51 is not receiving the signal! Lol!
YES HE IS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
he is FUNNY
ohOH, R-51 did a smart thing-a-ma-bob
The radio wave making the lightbulb light up is very cool.
Very nice.
learning about radio waves being invented was interesting today.
I thought so too!
Hi from Dallas
R51 is so funny!!
i love this
loved this live very much
Funny
Hi, Keegan from Montana. I was curious if you were to expand the amount of cups filled with tin foil ,would you need a bigger spark?
Ahhh yes, my favorite parts, the R-51 scenes haha
I love science live!
Hi from Baltimore
I only ever see Led lights. I haven’t seen a different bulb.
How powerful does the spark need to be to make a light?
Comment so interesting thank you guys
In the video learned about radio waves, and how cool we can communicate through radio waves.
Thanks for the advice
I find it interesting that an everyday object can produce radio waves
How everyone is doing well!!
Can mold emit light?
Very fun experiment for this week! Excited to see the one for next week.
hi 51!!
Love the videos! cant wait for next week!
He is soooooooo funny
Area 51, whats wrong with you!
Hello 51
Love what you do, and your science lives.
Area 51 rocks!!!
I was very fascinated by the segment about LED’s.
that’s awesome!
oh R-51
Could anyone be a keystone inventor if the wanted?
Hi Mia! I just wanted to say I think anyone could be a keystone inventor. Have a good day!
I can’t wait for the kit
Fun to learn new things!
Thats cool!
I don’t have any questions today but thank you for another great science live
Radio waves are so interesting!
I really like learning about morse code!! it seems really hard though
This is cool to watch radio waves are so cool to learn about .
I think it would be cool to make all the lamps in the future with LED light.
How many credits will the kit cost?
How can I make a light with a switch?
Comment Wow. Dr. B in Area 51
yes I have plenty of points
Hello from Tennessee!
We love R15!!
Julissa from Georgia here! It’s so fascinating to me that there are people out there creating devices that help us learn the factors of the importance in our sweat.
This is very interesting!!
I love this
Hi from GA. Great science live episode!
Can you use other things other than a liter for the spark?
Can you use a plastic cup or it has to be a glass cup?
I love you Miss Pajet and Mr Roger Billings
Im always looking forward to science live
Hello! from South Dakota
Hi from Mississippi!
Is Elon Musk a keystone inventor?
How powerful does the spark need to be to make a light?
Can other mold protect from radiation?
nice video, as always
I love science live
Acellus is the best school ever!!
Im enjoying so far
Nice job this week! See you guy’s next week.
Hi from Florida! Love science live!
R-51 is Pajet Monet’s favorite student.
Love science live
Hello! It’s Logan from NC, enjoying this science live.
Hii i’m very excited for this science live.
Would it matter if you had foil on four sides of the glass as long as they are not touching?
I wonder what would happen if you increase the number of foil balls or the size of the foil balls?
The sparks were really cool because the spark sent a radio wave.
Is it possible to make a powerful spark that would be considered “the master spark”
Another valuable lesson on why inventors are so important!
I find it really cool how someone found out you can communicate through radio waves.
The Keystone Inventors are really the backbone of engineering
A keystone inventor is an intriguing concept.
Hi from Tennessee! Wish I had the stuff to recreate that experiment , but i wonder what happens if you add more or less metal powder
Can you use any type of aluminum foil ?
interesting to learn cool how it works
I love the experiments omg
HI, it’s Mahek! This is a really cool thing to learn about. I didn’t know a lot about radio waves before, but now I have a better idea about how they work.
Hi from NJ! I love watching Science Live every week.
Saying hi from Catonsville Maryland! From Amina and Asiya! Another fun week of Science Live!
radio waves are very cool
It is so fun learning about radio waves.
This is awesome so much interesting information
I do not know where you get metal power from
About how long would it take to make it
You are so fun to watch.
r-51 is so cool I love watching him.
you always make my day
I liked the experiment!
That’s so awesome!!
“Keystone” haha the way she said it
Hello! This science live was so amazing!
