The Acellus 4th of July performance was a masterful tribute to our nation. The choir’s harmonies were rich and precise, filling with sense of unity and pride. Dr Billings’ words were deeply moving and a powerful reminder of the values that bind us . It was an honor to be part of such an inspiring and meaningful celebration.

It is really cool that members of our military got to be on stage! It’s a good way to honor our soliders.
the flag trick was good
My dad served in the air force
It was great to see all of the people that I see each week on Science Live singing and dancing.
Seeing Tobias sing and Lady Pajet dance with the robots was really entertaining. The best part was hearing Dr. Billings talk so wonderfully about our country and President Trump. That was really inspiring!
250 Years!! Bless every single person who served for our country! Great live this week!
I love this episode of science live. My mom teaches government and history and she often talks about respect for our military. I loved to see this episode – and the dancing
I loved all of the performances! They were amazing! And thank you to everyone serving our country!
America rules. Just think 250 years later where we will be. May Democracy and freedom ring.
God Bless America!!
That was so awesome and so fun to watch! So moving with all the singing, and powerful scenes showing the courage of our troops and the history of our Nation. I’m so proud to be an American. DrB is right… I can see what he is meaning. Scary times we’re in to see how the future unfolds like. But in the end, I know for a fact, that us American’s won’t give up our freedom that so many have given their lives for, it’s sad but we will prevail!
Thank you DrB and everyone! Was incredible to watch and it’s one that I will share with my mom and dad and watch many more times honestly.
Thank you! Happy post 4th of July!
The song about America and it’s freedom was pretty good!
Happy 4th of July everyone! God Bless America!❤️💙

I liked the trailer for the new class
I really enjoyed this video. There was a bunch of songs. My favorite one was the last one with everyone. I wait to the Hoover Dam for Fourth of July. And I did a whole tour and got to see the 250 feet flag I really enjoyed this episode. And it was one of my favorites. I wish you all a good happy Fourth of July.
Salute to those who fought for us we won’t forget you
I wish you didn’t have to go
Tobias has an incredible voice! I’m very proud to be an American! GO USA!!!
Thanks for a great year of Science live.
The musical was amazing! I didn’t know Mr. Tobias had such a nice voice! Happy 250th birthday America!!!
I really liked the dancing of the 5 ladies to the 1940’s music. It was made me want to dance too! My mom and dad served in the military. Happy 4th.
Great video! Along with the Acellus world video this is one of the best specials of Science Live.🇺🇸
This is why I love America!
Music has always spoken to be personally, but when they sang Lee Greenwood’s “God Bless The USA”, it was probably one of the most powerful things here for me personally because to me it’s more than just a patriotic song. My grandmother used to love that song before she unfortunately passed away in 2017, so it’s one of those songs that’s very near and dear to my heart.
Also, just a sidenote, but Tobias has an amazing singing voice that genuinely caught me off guard in the best way.
Happy 250th birthday America. Someday I hope to serve for our country ‘’America’’ just like my dad did. I loved the singing and dancing you guys are so talented and inspiring. Happy Fourth of July beautiful amarica.
I’m happy for 250
years anniversary
For July 4, I marched with Scouts in a parade. The front line of scouts carried a big flyer that displayed the Constitution and the rest of us carried U.S. flags. Each flag was slightly different because each one represented a different time era. It was so cool.
All of it was so amazing that i am happy that you guys did this because those who served for use they did an amazing job in keeping us safe so thank you America for being our home for what it has become today.
Happy 4th of July God bless all the men and woman who served this country and thank you beautiful dancing thank you acellus great show
I’m so grateful to be able to celebrate our country’s 250th anniversary.
Thank You ALL who gave me hope for my nation!
I felt like our nation WAS falling apart and as a Civil Air Patrol I hate to think that we are divided and were falling apart but I could see it happening.
But now I see that there are people all over this nation keeping us together no matter what happens, including our President!
I see the Acellus team cares for our nation ! BLESSS U GUYS
I am a Tech Sargent in Civil Air Patrol and learning that everyone can lead- My prayer is that all of my fellow cadets, friends, and those I do not know, work to make this country the best place ever for generations to come!
GOD BLESS AMERICA!
