a new adventnier that’s so cool I can’t wait to see what she has to say aboute it so excited
It was cool learning about infrared light.
I love film! Perked up when it was mentioned in the beginning!
I loved this one i learned so much!
I love science live!!
I want to experiment with mirrors now.
I also really like how water spiders live mostly under water
I loved this science live cause i got to learn about the water spider which i didn’t know there was a water spider ~Abi
I loved this science live I like how water spiders glide across the water
Loved learning about the water spider! How cool that a spider can swim under water and blow bubbles to breathe.
loved this makes me wonder if i can make a clock
I have seen water spiders before.
Water spiders.. learned something new. Always a great show
The spider looked so cool.
love to learn about rainbows!
I loved this science live video so much!
Hi from Illinois! Another great Science Live!! The water spiders are so interesting I would like to see how they eat.
I never really liked spiders but learning about water spiders was intriguing to me.
the potoges are soo funny
It was interesting learning about how each color of light has its own temperature
science + live = awesome
In binary code, the number 9 is written as 1001, what happens to the counters display immediately after it his this number?
The web is really cool with the spider I did not know that spiders could so that
The water spiders were really cool and what they did with the aluminum I thought was very interesting.
It’s cool that the water spider can suction water to its body.

Here from Texas, these videos are so interesting to watch!
very cool episode, i loved the spider!
R51 is cool!
Water spider are so neat!!!

The jokes at the beginning of the science lives always crack me up! lol!
science live time again yay.
Hii from Maryland
I ❤️Science Live!!!!
Wow!! Thats kind of scary knowing theres dry spiders hanging out in the water, but the hydrophobic properties are really cool!!
I loved the water spiders! They looked so cool, I really enjoyed learning about them! Thank yall for teaching us about so many interesting things!
A hydrophobic boat or drone sounds so cool.
Great live, the spider was pretty interesting.
Hello everyone, from jordynn
I really like how mirrors can reflect the colors of the rainbow.
This was so interesting and fun to watch i loved this.
Water spiders are so much cooler than i thought.
Wow I didn’t know different colors had different temperatures
I liked all the topics on this science live especially the water spider!
I learn so much from these science lives!
Water Spiders and Binary Decade counters! This was so interesting.
Why do different lights have different temperatures
This science live was very cool and interesting! Can’t wait for the next video live.
I loved this live thank you!!
loved “the protégés” as always! the water spider was very cool to learn about, thank you for science love!
That dance robot is so cute!!!!!
How do things become hyrofobic
This was a great Science Live. I really enjoyed it.
Thank you so much for the video. I like the spiders!
I never thought that electronics could do this, it’s very cool to watch!
Thanks for teaching us more about technology.
Wow! These new hydrophobic materials could do almost anything. The thought of unsinkable ships and buildings that can be protected from rain and storms sounds almost too good to be true! I really hope even more technological advances happen this year!
I enjoy these videos so much 💗
I loved this science live! It was so cool to learn about the water spider.
I loved this episode it was so cool.
I loved this video with spiders, circuits, and light splitting. I learned so much and I love R51 he’s such a goofball🤣😂
I love all the information about the circuits! Science is so cool!
I really like how mirrors can reflect the colors of the rainbow.
It is really cool how circuits need so much energy but it’s really easy to make.
I found myself intrigued with the binary decade counter and how they work, as well as the water spiders! I look forward to next week, keep up the good work!
I never knew that electronics could do this! Than you so much for the new Science Live video!
I loved the potoges presentation today
the water spiters were super cool it was my faverite thing in todays live
that spider looks so cool!!!!!!!!!!!
the super aquaphobic material can be used for phones and electronics so that they don’t get wet and malfunction. From South Carolina.
Hello, This is Erika from Texas. I enjoy this hour. This is great information, especially the students’ personal experiences sections. Maybe one day I can be there.
Me too 🥺
This episode was interesting and easy to follow. The science demonstrations made learning about circuits more fun.
R51 is so imaginative
the first joke lolol
Are we going to be able to buy that little robot online?
How many flip-flops are needed
i did not know differant colors of light had differant temps
How many years does it take to become a scientist?
Hi from ohio!
Hello from VA.
Water spiders remind me of water gliders
What does the water spider eat?
It is really cool how light can be split into multiple colors and each color has a different temperature.
It is cool to think about how you can use light in different colors.
Is there any inventions that already use it like this?
i have seen a lot of science teachers and videos of different people its cool.
This was really cool!
This is so cool!
This is awesome
seeing metal float is cool
Circuits and how they work/operate are very interesting!
I really enjoyed todays video it was vary educational and I learned a lot

Great live this week! Iv’e never seen metal float before 🙂
Loved the robot!
A Binary Decade Counter is a digital circuit that counts from 0 to 9 in binary form before resetting back to 0. It is also called a mod-10 counter because it has ten states (0000 to 1001). After reaching 1001 (which represents 9 in decimal), the counter resets to 0000 and starts counting again.
Hi I am from Brazil and I liked the part of the spider and when the robot dancing
I enjoyed Science Live tonight. Watched from Parksley, Virginia.

I really love to learn about circuit and how they work. Aera 51 is so funny that i laugh so hard. I really love to learn about robots. Thank you so much Acellus for teaching me new stuff.
I think the social emotional class is very important and definitely should be taught in schools, public and homeschool.
Another great live! my grandfather uses a thermal imaging camera for his business so that was nice to recognize that portion of the show. Also that spider is now my new favorite other than the jumping spider im trying to purchase!
that information about the spiders is cool!
My personal favorite from today was R-51!
I never knew metal could float to be honest that was fascinating to learn
I love science live
