Welcome to the Inventioneers’ Club, Claudia!
I enjoyed watching this science live!
This is really cool, I love this!
What other things can the integrated critics do. my name is David
Binary number are really intresting!
hi from CA,,
If you made a boat out of the hydrophobic metal will it be faster?
I have an amazing invention for the future!
hi from TX
Wonderful new robot!
7 segments EVERYWHERE!!1!
How is R51 this week? Congratulations Claudia
How do you convert binary to our normal counting system
WOOHOO!!!
Amazing lesson! I learned a lot.
learning about infrared light was pretty cool
Could you make some instruction videos for the activities on circuits?
hi from Maryland
Hi from NC!
The protoges taught me alot about the 555 and flip flop i enjoy watching them every week.
hi from florida !
That is such a cool robot guys! you should build more of them for your students
Circuits are so cool!
LOVE ACEIIUS☺️
I like the robot
Great job Caleb and David!
This was an entertaining live learning about the 555 Timer Chip and Flip Flop.
How long is it going to take to 3D print the giant ACD2 that will be used at Acellus World ?
I hope you all at science live are doing good and have a good week
Great lesson! Student from NH
Caleb and Dave are the best teachers!
watching from Puerto Rico
Hi from NV!
This Science live was very interesting
The most interesting thing I learned tonight was how you can change how a counter by adjusting the integrated circuits.
What is the biggest integrated circuit ever made and what was it used for? What about the smallest?
That will be an interesting challenge!
the robot is bigger than i thought, wow!
I think that the flip flop won!
Learning about integrated circuits was so fun.
Wow so cool! I’m a 555 lol.
Well I’m actually555lol

Caleb is so funny.
lol I agree
It’s amazing
Love ❤️
this is so interesting
This live was so cool I loved the way the metal floated😁
I loved the demonstration
I have really enjoyed and learned a lot from my social emotional class.
Hello from Rhode Island. I really enjoyed tonight’s science live.
Why can that aluminum float even with the lines that is bumpy?🤯
Good stream.
Good luck in the science fair!
How Did They put all those little tiny pieces together into a circuit?
The way the circuts work make so much more sense.
I enjoyed the protégé. I think they are really funny and really cool. Thank you for all you have done for us.
Hi!! from texas!!
Loved this live! -from Georgia!
same lol
Very cool live
may you allow the protege’s to teach a class about inventioneering?
Great idea! I hope they do!
Comment is R51. Sociable
cool live
Í had a fun time learning
I enjoy learning about Integrated circuits. They consist of so many parts like resisters and capacitors.
This was such a cool live!
I think I’m starting to get it
Who invented the aluminum that floats
for real I need of of the stuff!!!
