What if my dog ate my science fair idea? 🙂 A joke, clearly, but boy is thinking of new ideas harder than it seems! I hope everyone who is participating is coming along with their projects!
Some of that was over my head, but still a great episode of Science Live!
I love watching Science Live
I look forward to science live every week
Wow Kelsey! That’s amazing!🤩
congrats kelsey!
I LOVE SCIENCES
This lesson made me want a robot even more!
I never knew that some colors in the rainbow were hotter than others!!! That’s so cool!
When is Acellus world this year?

I Love watching Science Live
Science live was so interesting today I can’t wait for the next episode!!
i like how it explains binary
do the transistors always struggle to switch a page?
I never knew spiders could live under water, that’s so cool!!
Loved the rainbow part!
its cool that you can make things water resistant
Wow! The water spider is amazing!
Wow, Kelsi (Kelsey?) sure is super busy! Congrats on all you’ve accomplished! I bet learning animation was hard.
I want to program a robot!
I enjoy learning about all the cool things they teach in science live.
I liked the part about the water spider. Very interesting
Colors having temperature I have never thought of, that’s neat!
I love the robot dancing.
I didn’t know that each color has a different temperature science teaches me a lot
My favorite thing was learning about the water spiders. They make little air bubbles to breath under water, and they reflect water off their body to float. I always like R-51.
I liked the hydrophobic metal that can float by small cuts and holes in it. It seems to go against logic because metal is heavier than water, but by making cuts, air is trapped against the metal. The air adds buoyancy allowing the metal to float.
Never knew there was a spider like that!
Acellus is really great.
To think such great advancements were made in a time without technology like we have today.
I love Acellus live
I love the part of science live where we hear about other students accomplishments!!
how long until the prototype for wave energy is built?
its so crazy that different colors have different temperatures
Hydrophobic things are so cool!! I used to have Hydrophobic sand and I loved doing stuff with it.
This was really cool. Science is so interesting!!
I loved learning about the term hydraphobic and that spiders are hydraphobic and can breath underwater. I never knew that. The super hydraphobic theory is fascinating and that could be really big one day.
Great episode, I love science!
I would like to learn more about hydrophobic metal
What is the main function of the circuit, and what does it count?
I had no idea what a binary decade counter was before this Science Live and now, I have an appreciation for something new! This is just ONE of the reasons everyone should tune in to Science Live. It really encourages the mind to think about what it can invent!
Hi I’m Jordan
And I took the social class last school year and it was great! This year I am taking coding and some of it is really easy to understand but some of it is really hard but I won’t give up.
I think it’s really cool how they made it so the aluminium doesn’t sink!
Acellus is awesome!
What other interesting animals can we research?
I enjoyed learning about William Hershel’s discovery of Infarred light. I see it all the time on the ghost shows with their special technologies to see heat that is close.
School of fish, 😀 that’s a good one. I love the Acellus program so much.
I love the acda2!
what does a water spider eat?
Roger Billings is amazing.
This story was amazing. Thank you for sharing. I love science
This was a good Science live.
Great job today as usual! The first thing I thought that the hydrophobic metal should be used for is as an anti rusting metal.
I am not a fan of spiders although the water spiders are really cool.
I loved the water spider part!
Wow the water spider is really cool!
Great episode of Science Live!! I enjoyed it very much!
This was so cool to watch!!!
Great episode! I love science!
science live is so much fun!
this lesson was one of my favorites!
Science live is such a nice and easy way to learn. I love it!
The girl,Kelsey was amazing. She inspired me to follow my dreams.
Science is truly amazing!
Found it very interesting that each color of the rainbow is not the same temperature
I love fishing. The ocean can be really strong. That’s a great idea
i enjoy watching this with my sister
Love the live! How does the moon affect the waves?
I love science especially when y’all tell me all about it . it is so cool 🙂
Science is awesome! Binary is really hard though.
As an ocarina of time player, i love water spiders
I love science live soooo much!!!!!!!!!!!!
Hey from Thaxton, VA
Have you ever thought about doing this but different subjects?
This video was so fun to watch and I have always been interested in spiders and how they make webs !
Its cool every color is a different temperature.
It was fun learning about color and heat!
Learned something new about infrared light
The spider part was really interesting.
CONGRATULATIONS Kelsey!! Your such an inspiration!
The science is so cool in this video!
Who designed the dancing/singing robot?
I love the ending where David says “Check this out”.
I found the part about the spider interesting.
I never knew colors could have different temperatures.
I just started the coding class, I really enjoy it and hope I can get my robot to sing one day
Science is so cool
wow the water spiders are so cool!
Science is amazing!
Spiders are incredible!!
In what real life electronic devices are binary decade counters commonly used?
It is so cool on how Different colors have different temperatures.And how infrared is invisible and is ultravilotlso invisible. It is so cool how even with holes the metal was able to keep floating.
I didn’t know that much about binary decade counters but this was a very interesting thing to learn about.
I never thought about using the ocean waves for power! How cool!
I remember learning about the thing that repels the water, but I didn’t know it came from a water spider!
A giant AC-D2 sounds really cool.
congratulations Kesley! Keep up the great work!
Another amazing science live with so many cool facts!!
Welcome Claudia!
I loved learning about the Binary Decade Calender!
I’ve always been fascinated by the way a clock works. All the technology that goes into it is truly incredible!
hi from maryland
Would the properties of the water spider have helped the titantic from sinking?
How many total circuits are there?
I loved this weeks science live!!
I made up my own word too – “thinkability”. If you’re doing something like coloring, you can think a lot about something else while you’re doing it. That activity has high thinkability. But if you’re doing something like chess, you can’t think about other things while doing it. That has very low thinkability. Thinkability is the measure of how much thinking room your brain has while you do an activity.
I liked learning about warm colors and cool colors, why they are called that. Never knew about the temperatures.
Binary is cool
I love his story.
Very interesting science live, loved the robot.
Its awesome how each color of the rainbow has a different temperature
only at eleven wow!
Science is awesome
i loved this episode, it was so interesting!
I had no idea each color of the rainbow was a different temperature!
What got her into being an author besides inspiring people?
thx for the cool video <3
Binary is so cool!
I’m so excited to see more of the new member of the inventioneers!
Water spiders are cool!!!!
Heyyyy from Iowa!!! I love Science Live!!
I love his stories and his science
I enjoyed learning about the heat in colors and infrared light.
Science live is awesome!!!
I love this science live
Always love science
What is the maximum integer a Binary Decade Counter can count to
Thanks for the Science Live.
Love watching Science Live!!
The Japanese inventors were using waves to make energy. It’s very interesting.
Do we need tickets to go to science live in person?
I always love these science lives!
Now I know not to play football in area 51!
Great job Kelsey!! You’re so cool
Are you planning on adding any more graduation dates for this year?
AMAZING accomplishments Kelsey. I had no clue that each color of the rainbow are different temperature. Water spiders are Amazing things.
Can we buy the medium sized dancing robot with are gold credits?
Thank you for another amazing lesson!
I did not know that each color had its own different temperature that is truly amazing I also have a book of spiders my favorite is the wolf spider and tarantula
Today’s video was awesome!
Spiders are so cool!
could a hydrophobic spacecraft make a water shield on like mars to protect from dust?
Learning about a water spider was really cool.
I can’t believe that you guys are about to hit your 300th episode! To get to 50 or 100 or 200 is hard but 300!!! That takes a lot of time and work effort that has been put into this. Just truly amazing, keep going Dr. Billings!
Loved science live
This episode was awesome!
Science live is awesome! 👏
I liked the joke about fish being in school all the time.
I always love Science Live!!
Man, I love science live! 😄
I love being able to watch sience lives.
That 3D printed robot is amazing!!
Keep up the good work!
OMG so cool
Favorite week so far!
congratulations Kelsey
This lesson helped me understand how flip flops are used in digital counters
i didn’t know that each color of the rainbow has a different temperature!
The spider was so interesting to listen about!
learning how different colors had the different temps was so unique and amazing!
I like to think about there being colors we can’t see!
Learning that colors have certain temperatures is very interesting. Congratulations Kelsey, you have inspired me to working on my writing skills so maybe I could write a book one day.
Awesome what science can do
My favorite color is blue. I think it is need that is a cooler color than the red.
Really cool! I learned a lot of things I didn’t know about.
Thank you!
Watching the water spiders was pretty cool, it reminded me of that one animal called the sea butterfly….not sure how though 😅.
Aren’t most discoveries based on other discoveries?
I love science live so cool
science is amazing
Learning about the hydrophobic surfaces was really cool. Thank you for explaining it so well.
loved his story!
I don’t like spiders, but the water spider is amazing. Living in the water in a bubble to get oxygen is so neat.
What happens if you wear the aluminum and would it be better than life jackets?
hello from Texas
This video was extremely interesting!
I love science live!!!
