Hello there, everyone at Acellus. I have a question for you; is it or will it eventually be possible to harness a black hole and use it to conduct or produce electricity/energy?
Great live tonight! Thanks guys!
Hi for South Carolina
That was so interesting. The robot was the best.

Hi from Mexico.
The diving bell spider (Argyroneta aquatica) is the only spider that lives almost its entire life underwater, building a silk โdiving bellโ to trap air for breathing, hunting, and mating. Thank you for another wonderful science live canโt wait for next week.
Hello from Massachusetts!!!
infrared is such a cool thing! you can see heat in complete darkness and can see heat through a bag!
Omg I want the big rtd2
It was nice to see it from kentucky
Living underwater sounds fantastic, so I’m sure being that spider must be incredible.
I am a 555 , the binary divider is so cool
This was such a cool episode, I loved the proteges and r 51. See you all next week.
Thank you all! See you next Wednesday!
In what year did they release the first robot?
I find it very intriguing how the note ties together several classic IC building blocks into a single, functional counter system.
I canโt wait for episode 300.
Hello Ms. Monet and Mr. B, I would like to ask if a pen-like erase would be a suitable option for my project for the science fair. A eraser pen is an eraser shaped as a pen, and this eraser can erase ANYTHING (pen, marker, lint) that type of stuff. My question is, will this project be worth my time (ps answer on live so I know!!!!!) Ty
Love Lynzie cloud.
P.s- I am such a huge fan, and Ms,Pajet Monet is my favorite teacher!!!!!!
Ty for your very important time!!
learned a lot tonight. looking forward to next wed. goodnight everyone!!
how long did it take to find inferred?
Wow! A gigantic robot is extra cool!
Thank you all so much again this was another amazing science live see you all next week and I hope you all have a good morning, Good afternoon, and goodnight to everyone wherever you are!!!
wow! infrareds really cool! I always learn something new :-]
*in billings head* “I may regret this some day”
