I liked learning about infrared light.
The water spider was cool!
That was another really cool video. David and Caleb always have a really interesting topic.
You can learn so much from Science Live 🥰💡🔬
That was an interesting video. I enjoy learning new things every week.
These weekly video’s of science live always make my week, this school is awesome.
I did not know Sir Isaac Newton discovered infrared .
coding is pretty fun
You always gotta love the start of the video.
Water spiders got me intrigued .
“I was here, then i was here again.”
– Me, and a guy named Scott
This lesson was so cool!!
I liked the part that included the rainbow-scale wavelength that correlated with heat. Very interesting.
i like spiders
I love science it’s very fun .
What made him think that the different colors would have different temperatures.
I lovedx learning about the water spiders.
The floating metal is pretty cool.
That was hilarious.
I loved the video I learned so much cant wait for next week.
I love science its amazing!!
The part about rainbows was so cool.
This video was cool, I loved learning about circuits.
I never knew that the colors of the rainbow have a different temperature! That is so cool and crazy!
Water spiders are so cool!!!
Congrats Kelsey!
Thank you for this science live!
Binary coding always looked scary until the Tech class and this presentation. Thank you
Congrats Kelsey your accomplishments are so cool.
My favorite part was the integrated circuts. I also liked that it shows how they put it together.
I loved David and Caleb’s part!😂
I LOVE SCIENCE LIVE
I love his little song
The starting joke was a nice ice breaker to start diving into the videos topics
I like the water spider!
Science is so interesting!!
Science is my favorite subject.
As much as I hate spiders, the water spider part was pretty interesting!
Best friend- “hey! What’s your favorite color?”
Me- “infa-red” 😏😏
Best friend- “huh?”🤔
Science live is great
The Water Spiders are very cool.
I really love science.
The spider was so awesome and fascinating!
The water spider is so cool
I love Science!!!
Do water spiders provide benefits for the aquatic environment?
I love AC-D2!
I am so excited to see Acellus World! I don’t think I will be able to make it, but I might be able to online. Thank you for everything y’all do to make Acellus and Science Live possible!
I loved this one.
I thought it was cool to learn about the counting from 0-9 in binary before resetting digital circuits. Going off previous lessons I thought it was also cool to learn about the components of these circuits and what their role is in modern technology.
Very Interesting stuff!
I think it’s cool the spider lives in the water and makes bubbles to bring down to its web.
The color in the shady part of the rainbow has the most heat
who invented the first robot?
This robot is so cute!!
My brother got chased by a water spider while we were fishing! It ran across the dock at him! They are cool, but creepy.
Infered light is so interesting to learn about.
light is so cool
Spiders are so cool!
Will they put the hydro phobic materiel on ships?
These lives are always so entertaining and engaging, thank you for making them!
Congrats to Kelsey and I’m proud of her. This was an amazing story!
I loved how the rainbow’s colors had different temperatures, it was very intriguing.

Are some of the best science fair projects gonna be displayed on science live?
Hi it was so cool seeing the colors and how each one is different with each tempature!
What is a binary decde counter.
Kelsey’s accomplishments are not only inspiring, but also proof of the boundaries alleviated by Acellus’ flexibility! Congratulations Kelsey!!
I liked learning abut the water spider the most.
Being lightweight and unsinkable, would be great for ships!
Science is the best
A dancing robot has to be the cutest thing i’ve seen all week!
Learning about the binary counter was so interesting!
I love learning new things about creaters!
555 is so cool
Can’t wait for science fair!
I liked the whole light thing! Also congrats Kelsey for accomplishing everythinng with acellus!
Waters spiders are really cool
What happens if a flip- flop in the counter chain gets stuck in a high or low state?
this science live was amazing cant wait for the next one!
how bright did the red side get on the light?
I really like the show today. The metal that keeps floating is very cool.
Really fascinating video, loved the water spiders.
I wish I could come to oscellas I wish I could come to oscellas world it sounds so cool
Transistors are so cool!
I would love to watch the students animated film! Where can I do that
Football is for outside, not inside.
I thought the hydrophobic metal being built is very cool, and if used for things like planes or cars, could save lives.
can you either lower the prices on Acellus or make a way to earn coins calling from Kentucky
It’s wild how laser-etching a tube lets it float, even with holes in it!
I rely enjoyed his story it was very exsiting
I want that blue robot!!!
Thank you for another great Science Live!
I like learning about waves
science love is the best! >:D
This was really good episode.
Wow, I didn’t know that each color of the rainbow was a different temperature. That’s so cool! I also loved his fish jokes.
what was the vacuum tube made out of.
science is definitely my favorite.
I have never heard of a water spider before. Can the spider hold its breath any, or does it depend on the air bubble all the time?
wow the way that brain works, love acellus
Really good science live!
Always enjoyable to learn something new and interesting
Thank you for this fun and educational video!
Harnessing energy from waves sounds like a brilliant idea!
I really enjoyed learning about the 555 circuit and the flip flop circuit!!
This live was VERY interesting
I liked the part about spiders!
Counting using binary has always made more sense to me. It blows my mom’s mind. Cool video
I have that robot my mom got me it!
The water spiders were very cool!!!!
I loved learning about the spider!
how long can water spider stay on water for.
i love science lives so much
It would be great for life boats! Light weight to carry but can’t sink.
Are their any new interesting discoveries involving people trying to explore more of the deep ocean?
Water spiders are so fascinating! I can’t wait to learn more on the next ep!
water spiders are so cool!!!
this science life helped me understand how a binary that’s binary decade decade counter counts from 0 to 9 and then resets seeing how the flip-flops work together made it much clearer than just reading about it. Thank you for explaining it step-by-step.
I love technology Spotlight. It’s so cool and our 51 is so funny. He always makes me laugh.
I love the new word theory I thinks that’s just awesome!!
Congrats Kelsey, it’s truly amazing how one simple mind can do so much, it’s also awesome about rainbows!
I love these videos!
Interesting spiders can repel water
science is the best!
These videos are always interesting to watch.
harnassing waves is a great way to get energy, its a renewable resource
I love learning about the colors of the rainbows.
I wish I still had my robot!
The robot, dancing and singing was funny
This video was cool even though I don’t like spiders!
I loved learning about the “flip flop” circuit; it’s just so cool how they make it fun to learn even for the more little kids like my brother.
What is Kelsey animation called?
Love learning about integrated circuits
i loved how they turned science into a cool video edit.
I love this science live! Good morning everyone!
It was very interesting to learn about the water spider and you should make a plushy of one of the robots for the store.
omggg spiders scare me so bad haha
its amazing how a prism and a therometer created infrared vision
The Binary Decade Counter is cool I really enjoy watching science live.
Such a neat episode!
II hope we can make it to Acellus world one year!
omggg i HATE spiders hahaha
I loved the episode, very insightful
The robot and spider was so cool! I want a robot!
That robot dance was so cool!!!
God Bless Acellus!
So thats why my mom does not let us play football inside! Also this is so cool!
A specific spider can live under water and bring bubbles up to the surface because they can breathe in water like fish and they can make metal that can’t sink
Good job Kelsey!!! Just because you are young does not mean you can’t do big things.
i liked this episode and r51 is goofy
I don’t like spiders but the water spiders were fascinating!
ai is so smart
how do they make the laser micro.
This was very cool!
loved the 555 intergraded circuit!!!
this is awesome!!!!
Water spiders are such unique creatures!
I thought that ac.D2 was small
Congratulations to Kelsey!!
This weeks science live was very interesting!
Science is so much fun.
such an interesting episode this week!
I love scienceeeee, Thank youu!!
I love these science videos!
I love science 😃
How interesting that laser cutting on aluminium can cause a “bubble” that makes a metal float. What great things could we accomplish with this technology!
One of my favorite spiders is the water spider, so glad to see it getting the recognition it deserves!
I LOVE BINARY CODE!!!! BECAUSE i LOVE CODING!!! 101010101
I can’t dance! Not even as good as the robot.
Congratulations Kelsey you have a good life ahead of you
The spiders though!! SOOO fascinating
We love science
All of this is soooo cool!
Science is such a cool subject!
