Watching from Montana! *
I would love to enter the dance contest.
Hi from Texas!!!
th robot is so cute and cool!!!
Spot a fly, that’s funny.
Hi from NC
Hi from Georgia!
The part about the visible and the invisible was amazing!!! I hope we can learn more about it!!!
That is exciting news!
Comment This was really a cool video to watch
can I get the AC-D2 print file?
Did they try the super hydrophobic on other materials
I love AC-D2! I enjoy the robotics class.
i made a song too but i used ai to make the lyrics though so i didn’t plan to use ai for everything
Hi from Jack and Coleβs Mom, I hope you see this comment! I need to tell you your social emotional class is such a huge blessing to our family. We just added it this week as we are going through a very difficult time. What you tackle is so complex and important. You teach it beautifully and in such a heartfelt way. You are directly impacting the hardest things in my childs mind right now, his emotions and feelings. Itβs helping explain such big concepts in a healthy productive and encouraging way. Thank you so much for this class which will not only help him through this time but be with him for life. Thank you!
I hope that whatever you are going through gets easier and I am glad your family has found a way to help you through! π
Hey I hope you get through this tough time I know I did .
hello here for science live
Hi from Texas
Hello from Mississippi. I can’t come to Kansas City…
good live
sooooooooooooooooooooooooooooooooooooooooooooooooo cool π
Hello from Texas! Joined a little late but glad I made it in time for dr Rodger billingβs lesson π
Me too
Love your videos
Is it practical to utilize hydrophobic technology for building bridges over water? The reason why I suggest such an idea is; in the case that a bridge falls, in theory, it should not drown itself as well as the vehicles and humans atop it.
The new ACD2 robot looks cool π€©
Hi, I am always super excited for the science live.
i love the robot it looks really cool and Hey im from New Jersey.
hi from TX
sceience live this week is good
Hi from GA
ai is very impressive
How long did the robot take to make
Its so exciting when you notice so much in the real world that reminds you of what you learned in science and I’m so excited to see who wins that contest!!!
Hi from BRAZIL!!
hello from Texas I love science!
I’m saving my gold coins for the robot!!!
We can make songs with A.I now?
Hello from Millington Tennessee

Hello from NC!!!
I am from Louisiana. I like Science Live. I can not wait until Wednesday’s.
Hello from Tennessee!
Hello from Texas!
HI from TX
Does the big AcD2 work like a little Acd2? Can you make it move?
can you have a Acellus event in Georgia?
hello from Tennessee
how many people attended last year?
I love science, and I always wait for science live of Acellus.
“I learned that this year will be the highest amount of people at acellus world this year.”
Thank you Dr. Pajet for teaching SEL, I really enjoyed that class and thank you Acellus for offering it
When are you bringing the coherer kit into the store?
what if you are gradutaing but wont be able to make it kansa city will I still get a diploma
Infrared light is pretty awesome.
The history of science is very interesting
Buenas noches.

Hey from Kansas cannot wait to see what you’ll show us!
thank you for this video
I loveeeeeeeeeeeeeeeeeeeeeeeeeeeeee r 51
I was wondering why the robot looked familiar until I realized itβs a bigger version of the dance robot.
I wish I could be there!!
Do we have to enter the science fair?
how big will the big ac-d2
Do you ever have Acellus events in Ohio?
I liked learning about the water spider.
Good morning from FL!!!!!!!!!
I’m graduating this year, so I plan to attend Acellus World!
Social and emotional education gives kids the courage to stand out and be happy about who they are and accepting themselves.
Hi! From SD!!
The dancing robot is cool
hi from illinois
Can you film the unveiling please?
Can code carry over no matter the size increases
Hi from NY
The little robot looks really cool!
I wonder what R-51 will do today?
Thank you Ms. Monet for sharing what life lessons have taught you.
hi from cali
Hello from SD! I love Science lives!
So cool I would love to visit Area 51!
love these videos!! Hope everyone had an awesome Valentineβs Day!!
Great work roger
How did you make it in 3D but so cool I love science I like making stuff for 3D but I don’t really have 3D pins at all send
Can I get it for gold coins?
Thatβs pretty cool.
Hello from Mississippi!
love this! listening in from texas!
HII FROM WISCONSIN
Very cool project!
I have taken basic coding and now java.
A few weeks ago, I graduated middleschool social emotional and had the choice to do something else, but I chose to go up to high-school social emotional π thank you Dr. Pajet
Thatβs big π
Hi from Mississippi
Same omg π
Can we buy a giant ac-d2 in the Acellus shop?
hi from cali
Hello from ky!
Hello from Florida!
Would you say that the Acellus robot is the mascot of Acellus?
Hello from SC
I like the word “socialnol”.
that is the smallest robot i’ve seen
Can you use the super hydrophobic on rockets to travel better and land in the ocean?
I LOVE THIS
I really enjoyed this episode especially the part with the 3D printed robot!
hey from tx
Hi from VA!
Hi from ohio!!
So cool I would love visit Area 51!!
Wow!!!
Area 51ππ
With the social emotional class, you guys said that it was hard to get her to actually do the class. She makes this class look so easy and to be honest with me getting ready to go to college and trying to bounce back from bad choices this class really has been helping me. I have had a lot problems i have came accross in my life and so i was wondering if their is going to be a second part to the social emotional class to keep helping others that are out there that are in a similar situation as mine?
Wow that’s super interesting
I love science live it is so much fun and cool
is the coding different for the big Ac-D2 and the small Ac-D2?
Do you need to re-write code for it?
The fact that different types of light have different heat levels is crazy, yet unsurprising? It kinda made sense, yet still had a little bit of a shock behind it. Also, thanks Pajet! (Hope I spelt that correctly). You really have helped lotsβo people.
Thank you Mrs. Pajet for helping us become more socional
I think social and emotional education was a very good idea to teach, it Ives kids the courage to not be shy and to stand out.
Hi from Tennessee
How can you teach a robot to sing?
Hello from Michigan! I love the Social Emotional class!
wow that’s a cool robot
Hello from AL
I never realized ultraviolet and infrared were part of the light spectrum!
α΄‘Κα΄α΄ Ιͺs α΄ α΄ α΄Κ α΄α΄α΄α΄Ι΄α΄..π€£βπ€£ α΄‘Κα΄Ι΄ Ιͺs α΄ α΄ α΄Κ α΄α΄α΄α΄Ι΄α΄. But now I gotta say DuH! π€£βοΈπ€£
I had no idea underwater spiders existed, that is so cool!
R-51 what did you do π
i love watching these every wensday
Love this science live!
Hi from Indiana
Hi from Nevada!
Thanks for another Great Science live!
Thats cool how can he dance?
Woah I love the giant robot you guys brought today, from Area 51! I’ve seen this bot before in my coding lessons before, but never THIS big!
From Chicago hey!
Interesting how the infared camera works and was invented and was based off of one of Tomas Edisons inventions. I wonder if the black light was also based off of Tomas Edisons lightbulbπ€ Cant wait for next sience live
I amexcited about the robot
Hi everyone. I like the robot.
Hello from NC!!
Not gonna lie, im gonna be kinda sad when I graduate and these Wednesday night videos are over
Hello from Michigan
what is the purpose of the robots?

Hello from CO!
hello from nebraska
I love learning about robots.
That’s quite a large RC-D2 you have there!
Wow, after so much time a scientist made new ways to make things and that’s just awesome that I think they use that in the military. π π π π π π π π π π
That ACD2 robot was huge!
When is the high school graduation ceremony?
ACD2 Is the best part
We need a giant version of the ACD2 bot in the Acellus store!
Can you do the robot dance battle?
The Acellus Robot is so Cool.!
Good evening ! Great topics so far
Social Emotional is such an amazing course, it should definitely be taught in all schools.
I think it’s interesting that the square. The square the black square that thing when you put lasers on it. It will repell water because it’s now super hydrophobic. I just didn’t know. But it’s soo cool!
so I am starting to like science i think it is rilly cool
Thank you again for the lesson!
Can we buy these robots?
I love social emotional learning it has ben so helpful to me
Hi from Tennessee!!
I really want the big AC-D2.
hi from va
Hello from new mexico
love the robot
Big AC-D2.
