Now I want to see this with super conducting wire!

[bronsonstephens]

It's great to see other people this excited about Physics and science!!!

[BMSWEB]

Your reaction to it all was awesome :D

[EugeneKhutoryansky]

Very clever idea. Thanks for making this demonstration.

One of the things that I like about physics is the benefit of tactile interaction when learning a new concept. At least for Newtonian physics, it's better to get out and "play" by doing physics demonstrations before sitting down and doing the math. Virtual environments can also work well as a playground. Want to learn orbital mechanics? Play with Kerbal Space Program first, then go learn the equations. It's a faster and better way to understand the concepts, and makes it easier to use the math properly.

This might be my favorite episode yet. Seeing you have fun like that reminded me of my high school physics teacher. He got so excited sometimes he'd forget he was supposed to be teaching us. 😁

Dianna, you are honestly a wonderful soul. Watching your videos makes my day so much better, I'm in engineering but seeing all the neat physics experiments you come up with reminds me how fascinating even the more simpler concepts can be. Keep being awesome! 💕😝

[potterma]

I love these older videos, Dianna! So much fun watching your reactions :)

[moxshyfter]

I love the unscripted, down-to-earth feel of this video. You're incredibly charismatic and funny; it would be great to see your personality shine like this more often. :)

Wait... isn't everything all possible because of physics?

[PetterBruland]

Just found your channel, and I love it. I will be watching all your stuff with my kids, as you are wonderful at explaining the science. Thank you for being awesome!

[karl]

This channel is perfect. It's EXACTLY what I want to watch. This was so fun and I am so happy right now

[karkinissan]

Loved you enthusiasm in this video.
Can you do a video on the "simplest electric motor"? I would love to hear your thoughts on that one.

[Tux.Penguin]

You were having SO much fun, Dianna! Your enthusiasm is contagious! I couldn't help but smile :-)

[shk]

Had seen a video on how to construct this on FB but found no explanation as to how this worked. And it had to be the best person on YouTube to explain this! Thanks! 😊 Was basic Physics I remember from class but never applied in real life.

[TheSwiftMagician]

Another really fun video!… REALLY fun!! Thanks, and keep up, the good work!

[hedgehoga]

This has to be one of my favorite videos just because of how much natural fun you was having and how chilled it was =] Love all your vids however. Keep it up

[garyk]

I have to make this in a loop and see how the cat reacts...

[std]

This is the most positive physics channel I ever saw on YT, and it's surprising for me that it have such lack of viewers/subscribers. Dianna, you need to promote your channel more, asking for share and so forth - this is the _best_ channel about physics, really. Keep going, and wish you more people watching.
Best regards from Russia.

this was so cool! and super cute to see you excited about it! keep up the great work
