Why to some leaves change color in the fall? This experiment, Leaf Color Chromatography with Bite Sci-zed’s Alex Dainis, is the perfect autumn weekend project to learn about chlorophyll, carotenoids, xanthophylls, and anthocyanins.

Get some rubbing alcohol, white coffee filters, a few clear glasses, scissors, and a wooden spoon. Next, head outside to find leaves that are at different stages of their color change — around 10 per color. For additional info, read more about this experiment at SciAm

Frozen by Maxim & Katia Mezentsev, with music by Nebulo, could probably continue for another minute. Not only is it fun to watch, but it’s an interesting DIY project: freeze objects in blocks of ice, film them melting, and then play the clips backwards. What will you freeze?
