I would love if you put a kit in the Acellus store
Science Live is so Awesome
I really enjoyed this!
R-51 is the funniest thing that ever happened to my acellus life.
I don’t know about having mold for a pet, but if i did it’s name is gonna be Jerry!!
I am excited to see Dr Billings next invention.
GOT TO LOVE R51
I never thought about it before but our tv just turns on when we point the romote at it and click the on button
I love R-51! so funny!
Love watching Science Live.
this is an interesting video. I hope we get to do a science fair this year.
Another great Science Live! And science is like magic!
You mentioned how small engineering changes can massively improve energy efficiency.. could you explain how that applies to the new design you showed?
I think this science live was very cool!
I love science and magic!!
That’s a really cool fact about mold and how the astronaut can use it in space.
R51 is hilarious!
R51 is the coolest 😎 I love ScienceLive!!
Hi from North Carolina. This video was very fun to watch.
R;51 = The GOAT
I love r-51 he is so funny. Its my favorite part of the show!
Science live is amazing!
I always love seeing R-51! I hope I have enough credits for the new kit!
I never thought mold would be interesting to learn about but it was pretty interesting.
Very cool science live!
want a kit forsure
I love the little jokes you guys pop off here and there!! xD
I learn something new everyday
I ❤ Science Live and have a Happy Holiday🎄 !!! from Colorado.
R51 IS MY FAVORITE 😍
This episode of Science Live was so cool!
I liked learning that mold actually grows faster in space because of radiation, and how animals like frogs are adapting to areas even with radiation in certain areas.
I can’t wait to try to get the kit!
The radio wave was so cool! Thank you so much Dr. B!
I knew saving my gold up was a good idea! Looking forward to buying that kit!!!
I love these lives!
R-51 is hilarious!
I love being able to learn new things with Acellus!!
this episode really “sparked” my interest
its crazy that they told docter Billings that the hydrogen car was impossible!
it was really cool how when you put the lighter next to the wire it lit up
I love Acellus!!
Would plastic cups work as well? I was really fascinated by the LEDs! Thank you to all the Acellus staff and Dr Billings!
Science Live is great
This episode was fantastic
It’s amazing how that black mold grows faster in high radiation areas!
I love to see the new things added to the store. I’m sure it motivates many people even more.
WOW that is like magic i have got to try that soon.
Radio waves are such a fascinating thing to learn about!
I thought that the Coherer was an interesting invention.
Adalynn here just to say I found the mold section very interesting!
R – 51 is soo funny!!
Science is definitely like magic.
Watching from Illinois
R51 needs to teach a class lol
It’s so much fun learning about new things.
I always appreciate learning something new from science live
My goodness, R51 is so hilarious!
R51 is not a better inventer than DrB
its cool how the frog changed its color
My dad works nuclear and has told us the stories of what the radiation can do and several plants that have leaked the radiation.
Thank you so much for teaching us so much about inventors. It’s always so inspirational. Will there ever be a Science Live focusing on Accellus student inventors?
I love how you can never get tired of science live!!!
Hi from Pipestone, MN
Now I know the best pet to go to mars mold so warm and furry
How fast do radio waves travel?
I would love to have a kit. So interesting
The glass cup thing was cool!!!!
I really want to try this experiment at home!
Acellus is spectacular!
I love science live!!!!!!!
This was such a fun and exciting live! I loved seeing everyone’s reactions and curiosity—R-51 really made it entertaining, and learning about radio waves and LEDs was super cool. Can’t wait for the next one!
How does an electric spark make a radio wave??
I can’t wait to buy the, “I want you to invent something” t-shirt!
Thank you for today’s science live, I really liked when Dr Billings showed us how he turned on a light with a simple lighter.
This week was awesome. Love you guys.
this is amazing thank you Acellus!
I love R-51
first science live. very interesting!!
I love watching the science live!
ate a kids meal but his mom was furious is really funny i was laughing for a while
Always interested in the weekly science live shows!
Science live is fun!
My family recently watched a documentary on Chernobyl. The fact that mold feds off of the radiation is very interesting. I liked this science live!
🤩Science live is so cool
Will adding more balls or making a bigger spark make the light stay on longer?
R51 is so funny haha!
R-51 Was hilarious! 😂
I love learning new and awesome things!
very cool magic science
i DDNT KNOW SPARKS WERE RADIO WAVES. tHIS IS CRAZY COOL.
I learned that some animals adapt using biofilms to protect them from radiation. I also learned you can make invisible lights using diodes, and diodes are in TV remotes. I did not know that Maxwell was the first to come up with the concept of radio waves.
Inventing is awesome!
I love science live! R-51 is so funny!!!!
Thank you Dr. B for this episode. I think it’s so amazing how the light turned on with a spark. Awesome. (R-51 is soooo funny)
Tobias I love how u explain things in the past and present I am learning so many things
I like the red tie Dr Tobias is wearing this week, and his talk about the L.E.D. Is interesting.
Im excited for the kit in the store.
How did radiation change the color of a frog?
