Hey, @lucylin.

Is that butter? I thought it was cheddar cheese. :)

Pixabay can be funny at times. I type in a keyword, in this case, experiment, and that's an image I get. I think, Cool. I'd love to power a light with a carrot or slab of cheese. I mean, we generally have a carrot or two in the refrigerator along with cheese. So, voila, it's in my post. :)

I always wonder when I send things out into the HIVEsphere what people are going to take away from the post. :)
