    The video was about how fireflies are bioluminecent. They produce light by makeing this self made fuel that they can control by using air. They concentrate it to make the light, chemicals in their body make it irredecent. I really liked the song at the end it was very pretty.

    I love this. that song made me cry. I made a poem over fireflies.
    through the darkness,
    when life is full of sadness,
    there is a light,
    that glows with all it’s might,
    that night,
    it held on tight.
    That light,
    were fireflies.
    No matter the lies,
    or the darkness of your life,
    remember you are the fireflies light.

    Ok, I am going to admit that that was not a good poem, but when I write I write from the bottom of my heart.
    Remember you are the light of the fire fly!!

    Fireflies are really fascinating creatures, they are just so cute with those black bead like eyes and their glowing is really cool. I sometimes wish I had the ability to be Bioluminescent, especially when navigating my house at night when my eyes aren’t adjusted to the dark.

    I was pleasantly surprised by the new information I received. It’s one of the reasons why I hold Dr. B in high regard. He consistently shares honest and valuable insights that may not be readily available in traditional educational settings. This is why I hold Acellus in high esteem, as it has provided me with valuable knowledge. I also would love it if Dr. B makes a class with pajet Monet.
