    Favorite episode by far! Thank you for doing this special on our wonderful nation’s birthday to celebrate 250 years of freedom! The music was awesome, especially God Bless the USA. Tobias and Joseph, your voices are great! Love the “dancers”. Good job on guitar. You should start recording songs Tobias. Same with Joshua and Joseph. Who’s that dancing with grandson??? Lookin’ good, you two! Pajet, if you still want to be a dancer, reach for your dream! Clearly you are passionate. There is a wonderful new movie called Young Washington in theatres and soon to be on Angel Studios. If you love history, I encourage you to go watch it. Very sedimental little act. Thank you for your service. Everything you soldiers have done is deeply appreciated in the hearts of every American over the past 250 years. I love you, America. God Bless.

    I really like this episode of Science Live. It is great to see the tribute to America on her 250th Birthday. My favorite skit so far is Pajet Monet’s robot dance! Seeing the tribute to all of the Americans who lost their lives serving our country was very inspiring too. I loved hearing Roger Billings speech about President Trump and his praise for him. He is truly a great President and he should be an inspiration to all Americans!
