I think Tobias was a great singer and I liked learning about Dover and the ice. I had no idea that we could have a course only about how the country came to be!
Very cool to watch!
Thank you for this show. I really liked it.
I want to be more informed and I want to protect America. You’ve inspired me. I hope you may enjoy this beautiful holiday. I’ll inspire others as you’ve given a gift to me.
Thank you all for an exceptionally phenomenal, heart-warming Science Live! Keep the patriotism fire alive in American hearts, and blessed is this nation and its people, whose Lord is the Almighty God. Thank you, love you all, and happy July 4th, 2026!
God bless America, and I thank these soldiers for being here for us today. And I thank them for their service to America, and her people.

A Salute To Those Who Serve | America 250 happ fourth of July Acellus academy🇺🇲 see yall in September 🙁🙁🙁🙁🙁🙁🙁🙁
I am so proud to be an American. My dad fought for this country in the Army and seeing this made me really happy.
I loved when Tobias was playing guitar and when he was playing with willy Nelson it sounded great.
The part with the AI smart guitar was crazy. The new course by Todd Edmunds sounds really interesting. I’ve had a lot of Acellus courses with him and he is a good teacher. Thanks for offering a special 4th of July Science LIVE show dedicated to service workers. The service sacrifice part of the show was well done.
Happy 4th
Love it! Happy Fourth of July!!
I like how we honor the people who went to war.
