    After this episode, it’s going to be interesting to see how they turn Science Live into a course. Is it going to be like a permanent course that stays on the homescreen permanently and like a new “lesson” so to speak gets added for every new episode, or something? Like please tell me cuz this is so confusing to me but it also sounds cool.

    This legitimately might be the BEST Science Live that I have watched to date!! More of these special episodes and events, please! In a time that is very dangerous and oppressive to come out and support our current President, it is to have courage in the face of satanic evil like any American before us. We must keep fighting the good fight, stay faithful, and god-fearing in anything we do for this Christian nation. If we keep crumbling down like this, then the nation we once came to be will only fade into a memory. We CANNOT let that happen! Happy Independence Day everyone! 🦅🇺🇸
