Love watching science live videos! R51 is so funny!
How did the protoges get to acellus?
I can’t wait until it’s the 300 episode
The water spider was so cool! I love science live!
I always enjoyed binary
Hi from Tennessee! 🙂
Science is awesome!
I thought the part about the spider and the floating metal is very cool like you could use that for a boat that doesn’t sink
Its cool how different colors have different temperatures
Congratulations Kelsey!
wow ac-d2 grew up lol
When was the Acellus dancing robot contest first started?
love learning more about robotics!!!!
So excited to learn about spiders!
What is a binary decade counter
Science is so interesting!!
I didn’t even think about a rainbow having temperature
acellus is awesome, and so is science 😀
The water spiders are very interesting!
I seen a cool water spider on my cabins lake it was awesome to see one
That girl, Kelsey, was so cute. Water spiders are so cool. The science fair is going to be the bomb! A really big hit. Social emotional education is so fun. Oooo programing competition!
The robot dance was cool.
I loved it, thank you again Mr Billings!
I enjoyed Science Live
Science Live, thank you for another one.
I think the dancing robot contest sounds really fun.
Science is amazing
I think water spiders are really cool. I didn’t even know that they were a species of spider.
I had no idea colors of the rainbow had different temperatures!!
I love how entertaining science live is!
I want a cool robot spider
I have heard of infrared before but didn’t know what it was. This video helped.
I love acellus!
You guys changed my life and I’m grateful for that thank you
The water spider segment was my favorite.
Can the hydrophobic material be integrated into clothes so they can be waterproof?
Where is the Acellus home base located?
thank you science live for another science live episode can’t wait for the next episode!
The dancing robots so fun!
The water Spider is awesome!
I love science live!
How rare are water spiders?
That fish joke was a really bad pun 😀
This is my favorite video yet
If waves in the ocean can be harnessed would we also be able to control tsunamis and hurricanes?
I wonder if the new hydrophobic designs when applied to ships could increase their speed by decreasing the friction since they will be so hydrophobic.
The different color of the rainbow are already fascinating but, Dr. Billings blew my mind away.
I like the robot! I am excited to take a coding class next year!
Binary decade counters count from zero to nine, then reset back to zero.
todays science live was great learning with you is fun
it noice to see water spider and how rainbows 🌈 have different temperature
The water spider was so cool
It is so crazy that all of the colors of the rainbow have there own unique temperatures!
I never knew a water spider like that existed and could help us in the science world.
Love these videos!
The idea of the colors each having a different temperature is great
The rainbow temps are cool. I think kelsey is really cool.
I love the science live.
Water spiders are so cool! I love them.
it is so cool how each color of the rainbow has a different temperature
The water spider segment was really interesting. Great live!
Amazing video, I love science live!
It’s cool how each color has a temperature and the hottest one is the one we don’t see even back then they could make a tool to measure heat.
I can’t want to see the ships with the floating metal!
Why are they so interested in the that one spider?
Ive actually been learning about binary in my computer science course at school. It’s so interesting!
Kelsey great videos!
Learning about the spiders and hydrophobic aluminum was really cool. I wonder if the aluminum could be applied to the bottom of boats and ships for less wrecks during storms out on the seas and oceans?
I liked the hydrophobic aluminum
kelsey won awards for her animated work. I love that so much !
Thank you for adding the funny parts.
I love the science live so much !
I liked ACD2 dancing.
I enjoyed watching this video!
shoutout to Dr Pajet Monet for teaching socianal learning 😀
Thank you amazing video.
I love how unique creatures are.
I love learning science!
I had no idea every color of the rainbow are different temperatures, that’s so cool!
congrats way to work hard and finish your goals i cant wait for next weeks video have a blessed day
Its cool how all the colors are different.
Wasn’t expecting that picture of a spider
water spiders are awesome !!
The water spider was very cool
My favorite part was when R51 was showing off his Acellus teacher serum and his extremely fragile device.
This episode was really good!
The robot was my favorite.
Congratulations Kelsey your accomplishments are truly amazing.
I didn’t know that the different colors of the rainbow have different temperatures! I learn something new every time I watch these amazing Science lives😃
That aluminum will help with a lot of ship recks
Science is so neat!
I think it’s really cool how they made it so the aluminium doesn’t sink.
Spiders are so cool but yet so scary
I did not know that each color of the rainbow had a different temperature, how cool!
I love science
Hello from Mississippi
I loved this show! I can’t wait for the next science live
This one was really informational. Water spiders are actually really interesting.
Ive always been intrested on how water spiders actually float on water, and now I know.
It is so cool how each color of the rainbow have a different temperature
I didn’t know that each color of the rainbow had a different temperature
i also want that robot too i really want to know where i can get it.
I loved his story.
I loved learning about the water spider!
That’s crazy that the biggest number you can build with is ten !
WOWWWWWW
I have books on spiders! I loved seeing the water spider!
I liked how the colers where hotter then others
SOOOO COOOOOOOL
I don’t normally like spiders but the water spider was pretty cool see !
I love science live.
water spiders so coolllllll
Crazy that the colors are different temperature it’s so cool
So cool 🆒
The water Spider was very fascinating!
God’s creatures are amazing!
Yes they are.
I loved this video!
Thank you I loved the video it was so cool
Learning about the spider was cool.
yes so cool!
learning about the spider was very interesting
I love all animals the water spider was intriguing though!
The part of the water spider part was cool 😎!
Watching from TN.
What were cyphers like the Caesar cypher and the A1Z26 cypher used for in the real world?
The momma spiders bubble is awesome!
the water spider was really cool!
That spider was awesome!
cool robot
I really want it too lol.
I love the robot so much
The water spider part was very cool!

we love Science Live
Hello from California!
great episode I loved the little blue robot
Learning about aquatic spiders was so cool! I had no idea they existed, it’s amazing how the mother spider protects her babies!
I REAIIY LIKE THE SCIENCE EXPERIMENTS
Great show today!
science live is cool
Will friction reduce the hydrophobic properties of the treated aluminum? If it’s used in ship building, how will organisms like barnacles affect the metal’s hydrophobic properties? It can withstand damage, but to what extent?
How did the under water spider make me bubble and be able to breathe in it?
I want a robot spider, but I guess I can be satisfied by seeing them separately!
I loved this science live!!!!!!!
i love acellus <3
Learning about integrated circuits and how to connect different ones together to produce a more complex goal is interesting.
it’s really interesting to have discovered that every color has its own unique temperature and that we were able to discover even invisible color from old thermometers!
If the hydrophobic aluminum experiences friction, will the nano-sized strips in the metal smooth out, reducing its hydrophobic properties? It can withstand damage, as demonstrated, but to what extent? Say it’s used in ship building; How will organisms like barnacles affect the metal’s hydrophobic properties?
mother spider makes a bubble to protect her babies
thé water spider was really cool looking.
I love the proteges 🙂
This video was super cool! I loved learning about the Binary Decade Counter, but the water spider was my fav part!

i like the water spider.
I’m not a fan of spiders, but the water spider is pretty cool looking
That was funny 😂
I like the protgas
I loved this science live
Fun video! How long does it take to make an AC-D2 robot?
It was nice learning about how to make a circuit that divides by 2 and 4.
The robot is so cute! I would love to have one! I am also excited that Acellus Academy will be available worldwide.
I love to code robots! Hopefully I can make it to the con!
we can find science in everything we see. The beauty in how everything is uniquely shaped is truley amazing, I’m grateful for science!
At the end of the video i liked when they built the circuit 😀
BROOOOO Caleb and David’s part! They make it REALLLLLY fun!!!
This lesson is so well thought out!
Georgia from Texas and i think the spiders are super interesting.
Why do we need to harness energy from waves in the ocean, and not funny jokes.
Hello from Indiana!
I love math because I learn about time.
I love the big AC-D2 robot
I love Binary Decade Counters
Kelsey at 14 years old is such an inspiration. She has accomplished so much already in her life. It really shows she put her mind to it and made it possible for herself. She should be so proud of herself. She will do so much more I just know it.
I think it’s cool that Kelcey can do school with Acellus AND be an actress. I do school with Acellus, and I am a gymnast!
I just love science live, thanks for having me!
That is a cool discovery with the Unsinkable metal
Can you do more Science Live? please.
Thank you for your presentation. The spider was really cool! Robert “R.J.” Still, 9th grade
Science live is so amazing I love it
I love the robot
Amazing what Acellus is doing teaching social emotional education!
Someone’s life is amazing I love it
I wish I had a robot that was that big
interesting video this week!
It’s cool how the spider brought the bubbles under the water
To make a home
