A Rube Goldberg machine is any complex contraption that uses a chain reaction to perform a simple task.
HOW TO GET STARTED
Step 1: Start at the End
Identify the simple task you want to achieve. You could turn off a light, open a door, pour a bowl of cereal, turn off an alarm clock, hammer a nail or pop a balloon. Be creative — and unique.
Step 2: Make a Plan
Brainstorm a series of actions that will complete your task. Make a pin pop a balloon. Send a toy car down a ramp. Make dominoes fall. Draw a blueprint plan for what you expect to happen. The most important action will be the first step — that’s what starts the entire machine. Make sure your machine starts with a bang!
Step 3: Gather Your Materials
You can use almost anything to create your Rube Goldberg machine. Here are some ideas: dominoes, fans, PVC pipe, magnets, duct tape, marbles, cups or bowls, miniature toy cars, paper towel tubes, string.
Step 4: Build and Test
As you create your machine, follow your blueprint and place your materials where you think they need to be. Practice makes perfect, so don’t expect your Rube Goldberg machine to work perfectly the first time you try it. There will be plenty of trial and error — and that’s OK. Adjust your materials and keep at it.
