I like the robot!
I really like the proteges. Their lessons are very informative.
i love science live its so cool!
I love science live!!
this video was really. cool. binary started it all i like it
i wonder what the next science live is gonna be about
I love circuits!!!
Hello! Loved this episode especially the 3d printed robot! Awesome!
I really enjoyed the episode! I liked the infrared and the dancing robot!
Are those spiders ever found anywhere else besides in the water or do they naturally select water as their habitat?
Learning about the water spiders was cool and freaky at the same time!
I loved this live!! It was so interesting and gave great information!!
Science live is awesome!
I hope to get a 3D printer someday. With the skills I’m learning in coding I can make my own robot.
It is amazing what you can do with a 3D printer. I wonder what it can do 10 years from now!
How many tries did it took to make the metal super hydroprobic withe the lazers?
How can inferred red light determine how much heat an object is?
this video was so interesting ! science is so cool
I like water spiders.
I love Dr.Billings and his lessons.
I have a feeling that Tobias is a comedian as his side job 😂 He’s so funny! I love how he explains everything! 🩷
This was so cool >:D
I want my mom to get me that robot for the class and I like the leson on water spiders
I loved this episode! Such an inspiration!
Looking forward to today’s episode.
I really enjoy the new segment with the proteges. Their lessons are very funny and informative.
I remember talking about cinnamon with my mom and it’s a hydrophobic property and now I better understand what that means.
Great video i loved it
Great video Dr. Billings
love science live ❤️
3D printed robot is cool.
I didn’t know you can 3d print a robot that’s epic.
Good job kelsey!
Amazing!! loved learning about the water spiders!!
i like the water spiders

I think it was a amazing video I learned about stuff being hydrophobic and so much more thank you science live
This was most likely my favorite Science Lives Ive watched in forever!
i always love science live
yay Kelsey . I would love to attend the science Fair
Wow I didn’t know socional was a word or even how to spell that. When I first hear it I thought it meant she was very social.
Love watching the science live
This is the best episode! Thank you for the information
I loved this episode! Great info.
Amazing how many scientific inventions are inspired by nature and different animals. Very cool.
Wonderful episode! Good afternoon everyone!
It was interesting learning about the water spiders
Comment Wow i’m very afraid of spiders but that water spider is super cool. It’s amazing how the world works right.
very interesting, love your jokes!
Another great episode! The robot was cute, great dance moves.
It was so fun thank you guysss!!!
The underwater spiders are called diving bell spiders, I think. Super crazy how long they can stay underwater!
I like the robot.
I think is very interesting how a girl with 11 yeras old can write a book, i think is awesome. Other think is a fact is crazy a water spider can’t breath in the water but she need to state in there.
The 3d robot is so cool.
Congrats Kelsey! Very inspiring, seeing as I myself am an aspiring story writer
This science live was so interesting again
Its really interesting seeing a water spider I didn’t even know that it exists is awesome seeing one.
I love these videos the have so much information
The binary decade counter was cool!
Aww the water spider is so cute!!
the 3d robot was cool
It is incredible how quickly technology has evolved in such a short period of time. I can not imagine what is was like for previous generations. My generation is lucky to have the access it does.
Loved all the info today!
It’s so cool how something can have organized electrical pulses with something so small and that much accuracy.
I love learning on Acellus!!
Science live is so fun!
Me having that big ACD2 is my new dream lol
I love doing Acellus. Its so much better!
love the term socional
The water spiders were so interesting!
wow! thank you i love science live!!

I liked this one. It was entertaining. thank you
i loved the dancing robot
what’s up every one, another awesome science live am I right?
I’m not afraid of spiders and the water spider looks cool!
Wow! I always learn more in this school.
Great Episode, loved it!
Capturing the energy from waves as a source of renewable energy sounds very interesting but I have also heard that some scientist are also looking into capturing it from humans walking.
Mixing nature and science is cool like how they made the laser like that spider to resist water.
3d printing is fun.
Thank you for presenting this incredible information for us. Loved the dancing robot. Super excited to be able to code this one day.
this is so fascinating

I’m Harvey and I’m from Illinois.
How long does it take to make a whole circuit board?
What other species are hydrophobic?
Water spiders are so cool!
I never knew what ultraviolet was until now! That’s amazing! 😮
Why is the decade chip so important to a circuit board?
I think that the new metal process to make metal float will be helpful in building ships, boats and so much more! Does R-51’s Acellus Teacher Serum actually work? 🙂 🙂 🙂
I think spiders are cool
