This homemade chain reaction machine by YouTuber Creezy is made from cardboard, tape, paper, popsicle sticks, toys, books, playing cards, dominoes, Hotwheels tracks, and lots of not so simple simple machines. Watch Follow the Blue Ball (Chain Reaction Machine) to see how it all comes together in a long take that lasts just under two minutes and ends in a coffee cup. Creezy wraps up the video with a promo for the video’s sponsor.
