Water spiders are so cool
LOVE Science Live! It really activates your brain to truly think.
Water spider is cool.
I love R-51!
That was a really funny episode, thanks!
This was a great episode. I always enjoy the Science Protoges. They do a great job with their videos and explain things well.
That Ac D2 song is so catchy! Also can the hydrophobic material be used on boats to help them not sink
Great episode can’t wait for the next one!!
Hi! Carson says he is amazed that the spider has the ability to have pockets of air on its body hairs to allow it to breath under water.
how does hydophobic work? thats a question ive had a long time
the spider can bring bubbles to breath under water thats cool fr
So fascinating!
Can we do coding at any grade level?
Loved the water spider
i never knew water spiders exist, that’s really cool.
i love r-51 is so funny!! also i want some of the accelus teacher surem lol
I love this episode!
I LOVE THE ROBOT
What do electrical engineers do?
I love science live!
Thank you Acellus
Science lab is the best. R51 is funny
Finding out that white is just a combination of multiple colors was fascinating!
This was super awesome!!!
Is social emotional really a part of electrical engineering?
I didn’t know that about spiders. Cool!
I loved the jokes in the begining!
I love the 3d printer robot
It’s always amazing to me how people come up with ideas (like hydrophobic metal) by watching and studying things in nature first.
Thank you for this opportunity to delve into such niche yet interesting topics! I definitely am excited to see what each weeks lesson will be
Science live is cool.
This makes me want to build a computer
I love Acellus!
science live is so epic

I love this episode! thank you for the info!
I had no idea that colors were different temperatures or that white light is actually all colors combined.
Where does water spiders live?
I love Science Live!
It was great to see a real circuit being built! The protoges are doing great!
This episode was fantastic!
Spiders are amazing and they adapt very good to water
how do water spiders not float if it is hydrophobic?
It will always blow my mind how complex computers are.
The water spider was wild to learn about! Spiders are not my thing at all but those were pretty cool.
Best hour you can spend in a day 100%!!! Love from WV
I like how the 555 works and I like how the spider looks
