“Noooo Sister, NO touching the spinning thing, it's dangerous!”

They're so innocent, cute and funny.
“Kittens that discover the world of humans are so funny...”
“The standing kitty is so KAWAiiiiii!”
Sis: “Bro, what is that weird spinning thing, a mushroom? I sense danger.”
Bro: “Don't be afraid, spinning things have inertia, which means they keep spinning unless something slows them down.”
Sis: “WHAAAAAT? You're a genius!” 👀

Playful and fearless!
