Test the rainbow with two sweet experiments
A PIECE OF GREEN CANDY may look like a single color, but is it? Some inks and dyes are made of one color; others contain hidden colors. You can be a science detective and find out what really gives candy its color.
Chromatography is a way to separate out the different colored molecules in a mixture. You dab a substance, such as ink or dye, onto paper. Then you dip the paper into a liquid. As the liquid creeps up the paper, it picks up the colored molecules and carries them along. Different molecules crawl along at different speeds, based on how heavy they are and how well they dissolve in the liquid. The pattern of bands reveals what is in the mixture.

Who's Your Cousin?
The great apes are among the most popular animals in most zoos. Their actions, facial expressions, and family life remind us so much of ourselves. Have you ever wondered, though, how we might look to them?
Is it possible to die of boredom?
To figure out if we can die of boredom, we first have to understand what boredom is. For help, we called James Danckert, a psychologist who studies boredom at the University of Waterloo in Canada.

THE LEFT OVERS
A lot has happened for modern humans to get to this point. We lost most of our hair, learned how to make tools, established civilizations, sent a person to the Moon, and invented artificial intelligence. Whew! With all of these changes, our bodies have changed, too. Itâs only taken us about six million years.
