i think the octopus arm was awsome
I’m starting 5th grade tec and my mom said she is looking to get me a coding robot
This lesson was extremely interesting! Dr. John’s lesson on octopuses and their arm tactics was super fascinating; Dr. Tobias’s lesson about the SR-71 was also mind blowing. I used to like BB-8 the most, but now, seeing the powers of the SR-71, R2-D2 is appearing to be way cooler and more historically connected. Kelly Johnson and his team were true inventioneers, turning the impossible possible. Despite doubts in the begenning, they had hope all the way through, and all of his and his team’s hard work truly paid off. Using titanium for resourcefulness, strength and capacity was unimaginably smart, and applying that special black paint was very clever. Magnetism is also a fun subject, and all the resources and assistance it provides is unbelievable. I am also super excited to earn enough gold and get the Dancing Robot!
I LOVE the music playing when r-51 was hatching Snakey-51!
The octopus arm is so COOL!
Magnets are AWESOME and so fun to play with!!!
Magnets have a north and south🧲
i love learning about magnetic fields
Electromagnets are cool!
I never knew there were so many different uses for magnets.
It is fun to see the different ways magnets can be used.
Magnets fields are really interesting to learn about
Magnets are so fun and interesting!
It is great to think that by 2030 large companies such as BMW and Toyota may actually bring a hydrogen engine to market. The pioneers like Dr. Billings back in the 60s were ahead of their time.
Magnetic fields are pretty cool to learn about.
I LOVE MAGNETS!!!!!
To be hand picked by the president for a task is so cool.
This episode showed me how we can use magnets in different ways.
The octopus arm being controlled with only two strings was interesting to see.
what happend to r-51 what happend to him
Loved watching this!
Wonderful, thank you !
Wonderful video! Magnets are so cool!
This is brilliant!
Magnents are one of my favorite things!
thank you for this episode!!
Magnetic fields are wonderful!
Magnetic fields are cool
Would magnets work in space?
I did not know magnets could do these things!
r-51 should be learning about magnets too! (snakey-51 is NOT a pet!!!!)
Magnetics are super cool!
thank you!!!
Would magnets be able to work in outter space with there being no gravity, wouldnt they just not attach?
I really liked the snakey51 and r51
