Although spiders are quite terrifying to me, I have to admit the robot was quite cool.
The water spider really was what caught most of my attention on this weeks episode, really interesting how they can actually live like that.
I liked learning about the water spiders.
It was cool how the super hydroponic did not sink
I loved learning about the Binary Decade Counter with David and Caleb!
it was so cool how the metal floated after they made the little lines on it.
Using lasers to make it hydrophobic is really cool!
This is so cool!! hopefully next episode will be something about space????
This video was the best yet and so informative! I also just learned a bunch about ultraviolet before this video because I found out my kitten can see it!
My brother is trying to get acd2
A circuit that flips which parts are on and off when it receives a signal
I liked the dancing robot and the water spiders
Thank you Acellus! I love these Science Live. There is so much good information.
i loved this video it was so fun i love fun videos
The water spider is really clever! I was surprised the tube with holes didn’t sink.
I always found stuff thatβs hydrophobic fascinating since it canβt get get wet and when it goes into water it gets this shiny thin coating of air! And itβs even cooler that other species like the water spider are born with hydrophobic like parts on their bodies!
Loved the cool transition lol
socianal is good and can be a part of social and emotional health
The water spiders were really interesting to learn about!
I like learning about spiders! I want one, they are super interesting
I never knew about water spiders before. They are really cool and itβs so smart to make water bubbles to breathe water really cool video this week I learned a lot
the underwater spider was by far my fav thing today
Watching from Connecticut!
Science Live is so cool
Binary decade counter is cool
This was interesting AND funny!!
I didn’t even know water spiders existed so I learned a lot today!! Thank you
Science Live always teaches me so much and is entertaing at the same time!
Coming to Science Live every week, you learn something new every single day. And it sticks with you.
Thank you! I learned so much today!
The hydrophobic properites of that technique will be so useful for so many different fields.
Science live is so cool!
The spider was awesome!
science live is so coooooool!!!!!!!!!
Happy Lunar New Year guys!!!
The water spider was cool even though I have arachnophobia π
The skits were all very nice, great way to keep attention.
We’re finally here with a new espisode!
It was so cool how the super hydrophobic did not sink I learned a lot today Binary Decade Counter is cool.
I did not know that’s how spiders breath underwater, I didn’t know at all that they could either.
Really interesting canβt wait to see the next one!! π

I always wanted to know how water spiders worked.
Thanks from Vietnam for this very intriguing live!
I love water spiders compared to regular bugs
My favorite part was learning about the spiders!
Hi from Texas
I love water spiders.
Thank you for another interesting episode. I especially loved learning about the water spider.
I am just now learning why red & blue are identified as being hot and cold.
I didn’t know water spiders could breathe underwater.
Another interesting science live !
Learning about the water spider was very interesting.
The spider part was my favorite.
thank you very much science live!!
I loved watching the robot dance it was so cute!
Greetings from Kentucky
Awesome!^^
Loved this episode! The water spider was very interesting to see!
they found a specshil spider which is called water spider that lives uder water and use these bubles for air
r51 is so cool
Thank you for another science live
The spider was cool!
Super cool episode!!!
water spiders are quite interesting
the water spider seems super cool
This was a very cool lesson today!
Thank you for teaching us about the discovery of infrared light.
love watching accelus live.
It was cool to see the infrared light pass through that sheet but not his glasses. So neat.
Hi this is Laila from NY! This live was so entertaining and i learned a lot! Acd2 is such a cool robot and the super hydrophobic was cool to
the stuff with the flipflop was cool
I really loved this live, I learned lots of cool new things and am looking forward to the next live!
Loved the dancing and music
Loved learning about the spider! So cool.
What is Binary Decade Counter? π€
This was awesome!!
crazy to think that there is light I can’t see….
I would like to program a human sized robot to dance.
That is so cool, that Acellus students can be on the news.
I liked the way the robot danced.
I love Science Live!
Awesome live!!
What another great epidsode can’t wait for the next one!!
Does the binary code have a limit?
What will happen if the binary code reaches 9 will it start over? (0000) or just continues?
hooray this one was very good
The AC-D2 dancing steam robot was amazing.
How is the Acellus robot made?
ACD2 is so cool !!!
the hidrophobic spider is very intristing I wonder if we could do that to a car?
Wonderful live as always, keep up the good work!
how do a binary decade counter work and work and care for the earth?
I loved R2-D2’s awesome moves
This was super cool!
I loved this science live! It was so cool to learn about the water spider.
the proteges are always so goofy and funny
hi from texas
THANK YOU!! I love you guys so much.
Can you please say my name in your next video.
Awesome science live today!
that’s crazy that they don’t sink!
Wow! I found everything about the water spider so interesting! I will for sure me researching about it more later! I cant wait for next week!
I learned so much!! So cool!
ACD2 is cool
hi from missouri!
This podcast was really cool. I didnβt even know water spiders existed before this episodeπ
This was a nice video.
I was so fascinated by the water spider!
I loved this science live, great job everyone!!
William Herschel discovered infrared light by shining sunlight through a prism and placing a thermometer in each color of the spectrum. He observed that the temperature increased from violet to red. When he placed a thermometer just beyond the red light, where no visible light appeared, the temperature was even higher. This led him to conclude that there was an invisible form of light beyond red that produces heat, which is now called infrared radiation.
I love science live!
Binary Decade Counter is AWESOME!!!
Enjoy the lives so much!!!
The aluminum that can float can be very useful, it could be used for boats to prevent sinking.
ACD2 LOOKS COOL!
can we make a vest with spider webs
These science live videos have gotten me much more into STEM related topics, I will have to say.
I liked when Caleb went full social an emotional mode it was hilarious
its supper cool how someone can learn so much from a video
Thank you for these videos!
This was a very good episode of science live
I learned so much!
i love science live.
I love area 51 it’s one of my favorite parts in science live!!
Awesome episode! I loved it!
Hi from Germany!
The water spider was cool
AC-D2 got the dance moves!
My Favorite Science Live yet!
It was very Interesting when the aluminum was drilled with holes; it still floated.
Some of this went over my head, but I enjoyed it.
they should make a page about the proteges. like how they did it with the Inventioneering Club
Hello From South Africa!
I like this video because I love science lifve
I wonder what would happen if we made diving gear hydrophobic?
The spider is so cool!
I love acellus so much this is the best school ever!!

Watching from Utah
This is a great video, super cool!
This video is very entertaining and interesting, super cool!
The progression from learning what binary is, to how their used within circuit has been very interesting.
Sometime the best things are right in front of waiting to be discovered, and I’m really thankful of Science Live for showing me all of them.
Thank you Dr. Billings!
Prisms are very interesting. Itβs a cool idea how simply colors can detail so much about our solar system.
I love science
I dont really like spiders but the water spiders intrigued me
Could I make a digital clock with this???
This was so freaking awesome!!!!
I love science π§ͺ
Love watching science live.!!
I thought this episode was awsome!
