Found your link watching you on "its okay to be smart", as an ER nurse and now nurse practitioner I can finally explain why veins appear blue to my patients "optical illusion" love it, can't wait to see more of your content :)
Your show captures what I felt as a child watching kratts creatures or the magic school bus. Warm and inviting education. Great stuff
Unrelated question:
How big can a creature get without collapsing itself with its own mass ? Can Godzilla be real for example ? or King Kong ?

Thank you. I love your shows.
I’m surprised that this show has so few subscribers. I guess it’s just the downside to starting another RUclips channel.
Yes, BUT WHAT COLOR IS THE DRESS???? (jaykay, thanks xkcd! (xkcd.com/1492/ then www.explainxkcd.com/wiki/images/a/ae/dress.png ))
More critically: As near as I can tell from the clock on the wall, Anna stopped time to bring us this knowledge, so pay attention people! (Her powers continue to grow...)
the fire is so soothing.
Ok... here's a question... how come there are no visible satellites in the sky??? Can't even locate one with a telescope... yet, there are supposed to be thousands of them in orbit...
Science Rules!🤓 way better than Bill Nye the Science Guy ever was... & he's kind of become a pompous blowhard...
