this episode was awesome
This was fun to watch!
I love using magnets
Its interesting how we can utilize earths magnetic field as well.
I love magnets
Why don’t two magnets go together
Magnets are so useful and you can use them for so many different things which is really cool!
I liked the example of a big crane hook picking up a car with a big electromagnetic ball. Thank you!
So cool 😍😃🙀
love love loveee this video!
Magnetism is very interesting.
This episode was so neat, magnets can be so useful!
what inspired the hydrogen things?
This episode is definitely one of my favorite ones so far!!
this is so cool!!!!!!!!!!!!!!! thank you
Magnets are nice since you can use them for many things.
Magnets are cool!❤️
The octopus arm is very cool. I loved how the magnets. What is the strongest magnet ever?
Magnets are neat.
Magnets are so cool!
wooooowwwwwwwww
What are two types of magnetic poles?
Magnetism is so epic!
Magnets are amazing. This gave me some cool ideas.
Second time watching. ❤️
I love magnetization!
This is so cool!! I learned a ton about magnets from the last video, but this one taught me even more!
It’s so fascinating all the things magnets can do besides be great fridge decoration.
Magnets are so cool!
Interesting episode.
Wow i love magnetization
I think the tentacle based robot arm is super interesting! It seems a lot more coordinated than the more mainstream ones!
This video just made me realise how powerful the magnets are on those Maglev trains ! magnetically powered trains)
I love this
Magnetism is really useful.
I liked seeing the robot octopus arm. 🙂
I have learned about magnets before but never about how it is connected to hydrogine engine
I LOVE THIS VIDIO
Loved the video! Thanks for sharing about magnetism
I liked Dr. Johns part
Magnets are really interesting! I find them *ahem* attractive. 😉
Magnets are important, we use them in so many places and for so many things.
The dancing robot was soooooo cute. Octopuses are awesome creatures. Amazing story about the SR71. Area 51 was funny today.
I like how N and S represent the North and South like the Earth, which is very fascinating
The octopus part was very interesting and fun to watch. 😉
I thought the dancing robot was so cute
Engines are cool! Thank you for showing us how they work.
Enjoyed this episode!
Magnets are amazing!
I love these
That’s so cool how the electromagnets helped Dr. Billings in his hydrogen car.
The doorbell in my house is an electromagnet.
I love how magnets can pick up cars.
can magnets be used at home too?
I am curious to know how the octopus robotic arms could be modified to work fitted to human hands.
Magnetism is such a cool force!
Science live has taught me so much about magnets and many other things from past videos I really enjoy watching these videos. Thank you!
Magnets are so cool and fun to play with!
sknakey 51 is definitely my favorite part of this video!
Thanks for all the cool info on magnets!
I love dancing
What is the strongest man-made magnet?
How amazing is this!
Its amazing to me how many different things we can use magnets for!
I used to play with magnets all the time as a kid!
Dr Roger Billing, magnetism is so fun to learn about
this episode was funny
So funny and fun.
The first the video explains or gives information about connecting electricity from magnets. The dancing robot was exciting and interesting.
what would the world be like w/out magnastism?
the studying with Acellus Gold we saw that there was a dance contest with robot acd2. for the technology spotlight we saw robot ocktopus arms and how useful they can be and that gave me a idea to make a robot arm and no fingers but ock arms. at the breackthough moments in science we saw the guy talk about a super diffrent but better plane then any at the time. in rodgers science we saw the factory for toys and about magnitism.
What is the strongest magnet in the world?
This episode definitley aspired me to learn more about magnets.
Who first found the major uses for magnetism?
Loved the octopus arm
WAKE UP MR WEST
The octopus arm was so cool!
I loved this science live!!! I can’t wait to earn gold. I especially enjoyed snakey 51!
Magnetism is so cool
Without Magnetism, the world would be destroyed by the suns solar rays
what’s the difference between a regular magnet and electromagnet?
Tobias’ jokes are super funny, they brighten up my day!
Learned a lot about magnets from this video.
Coding is lots of fun.
Magnetism is interesting
Snakey 51!!!!
Free r-51!!!!!
Learning about Magnets is amazing
My mom is a doctor and is always talking about how dangerous magnets are if swallowed.
I really like the engine model very detailed
I loved seeing the octopus arm! Such a cool lesson.
Snakey 51 was so cute!
i really enjoyed the robot arms thought that was extremely cool😆
Learning about Magnetism is super fun!!
I love how Dr roger billing and venionnering and do magic thats cool one day I will be the best magician
I liked the octopus arm
Magnets are interesting.
Magnets are very fun and interesting.
i’ve always been really interested in magnets, this episode especially gave me good insight on them.
that octopus arm sure is cool!
I enjoy watching your past videos from before I started Acellus
So interesting! Thanks for another awesome video!
There is so much to magnets that I didn’t know about. Super cool
Was this plane related to the U-2 Stealth plane?✈
I think it’s more of an octopus arm not an elephants trunk because it does not have a nose to grab things at the end
As an aviation nerd when he started taking about aircraft I got very excited because from the first description he said I knew he was talking about the SR-71 Blackbird. Also the image shown with Kelly the aircraft he had his hand on is called the F-104 Starfighter. I can go on for hours about aircraft so if you want to know more just ask.
what are the strongest magnet
That snaky 51 video was funny.
I didn’t know Roger Billings made a book
Magnets are awesome I didn’t know they could do so much
Magnets are amazing
Magnetism is fun thank you for the knowledge, I am saving my gold coins to buy a backpack.
Seriously so cool
what’s the difference between a regular magnet and electromagnet?
Magnetism rocks!
Magnets are cool!
I LOVE magnets
Interesting to learn more about electromagnets and the hydrogen engine
The octopus arm that that scientist made is very cool to watch and the fact that it can run on only three strings is amazing.
I actually had no idea (probably forgot) that you could use Acellus Gold to buy merchandise, thanks for letting us know!
Thank you! this was very interesting
I learned that if you wrap wire many times around a piece of metal you can make a electromagnetic.🧲
Love this video!
I love love LOVE learning about magnetism!
Magnets rock!
magnets are amazing
How did the creation of magnets help our modern society advance overtime?
i love playing with magnets!
i love magnets so much!
R51 is very helpful!
When he started teaching us about the RS 71, it really captured my attention im going to do some more reasearch on it, thank you for adding that into the live.
Magnets are so cool!
Love it!
magnets are really something else! thanks for all the info Mr. billings!
Love this! It’s sooo cool!
We have evolved a lot with airplanes, and jets they’re just getting more and more faster by the year! I would say my favorite jet is the F-35b lightning II, the one that can fly vertically!
Magnets are so cool!!
i love coding!
why did they choose to use an octopus to base their machine on
wow
will the be able to make a jet that goes light speed? Another question is, is the tentacle a machine that uses code or do u have to control it yourself?
It was very shocking that when they were building a plane that could go Mach 3.2 and just
so they can know where they are they would use the ANS, and all it just did was look up at the stars, and it would know where it is.
I really liked it, thank you!
i love magnets they’re sooo cool!
wow so cool
COOLLLL!!!!
i liked the end with the snake that was very funny i died laughing
magnets are awesome
btw the black bird at high altitudes its fuel tank froze on purpose to stop leaks
When where magnets made?
We can do so much with the electromagnet. Making it upside down was so smart!!! I need to keep saving to get the book. Can’t wait
Cool plane
magnetism is very interesting
That was very cool:)
I throughly enjoyed this talk! So informative and interesting!
I learned that engines pull in air. Great video.
Area 51 guy is hilarious
It is so cool how electromagnets work science live has taught me so much about magnetic fields and magnets, I am also learning so much history about a lot of stuff. And it is also amazing how magnets were crucial for the hydrogen engine.
magnets make cool fidget toys too.
Thank you! for sharing the story of the SR-71. I loved watching this amazing video!
Comment if you want to see Dr.B
I really enjoyed learning about the SR-71. AC-D2 is such a cool robot! I loved taking the robot class! Magnetism is so cool and interesting. I know a lot more about magnets now!
Magnets have always interested me since I was younger
Very cool information about magnetism.
Magnets are some of the most interesting things. We have giant magnetic fields all the way to small fridge magnets. Magnets have brought us so much already but I wonder what more they can tell us about the world around us.
I think magnetism is SO cool!!
Does a voltage device determine how much electricity runs through the wires?
This live was truly fascinating
Using magnets in everyday life is super cool
love science live!
I didn’t realize the logarithmic shape was the one that had the most control, how cool!
Where do you think those robotic arms will be used in the future?
Magnets are cool
It’s cool how octopuses can pick a bunch of stuff with there legs it’s so satisfying to watch lol octopuses are incredibly smart
Magnets are amazing!
