When life gives you lemons, make lemonade. This optimistic phrase, encouragement for turning the sour moments of life into something sweet, sets the theme for an epic Rube Goldberg chain reaction collaboration: The Lemonade Machine.

This complex chain reaction travels through the kitchen, kid’s room, bathroom, office, parent’s room, living room, patio & backyard using everyday objects to automatically pour lemonade for the entire team of builders.

K’NEX pieces, Hot Wheels tracks, wooden ball tracks, blocks, and planks, fidget spinners, a skateboard, all kinds of dominoes, and other toys mix with household items in really surprising ways. It even includes a mini pitch drop-style green slime moment that’s sped up in the middle of the video.

The video collaboration includes seven prolific YouTubers: Sprice Machines, who you’ll remember from Red Ball Adventure and Green Ball Adventure, Hevesh5, a TKSST fave who makes awesome domino chain reaction videos, DoodleChaos, who syncs up classical music to chain reactions, popular online games, and more, 5 Mad Movie Makers, who made this awesome Thomas the Tank stunt track, as well as DrComplicated, SmileyPeaceFun, and TheInvention11.

Update: Go behind-the-scenes! Hevesh5 documented the whopping 86 takes it took to get the entire sequence to work on Falldown Day.
