Quick Answer

Build the BYO Fan Launch Challenge with Circuit Blox by assembling the wavy wire maze, connecting the circuit, and powering it with 3 AA batteries. Then test your steady hand—touch the wire and the fan launches.

Why the Fan Launch Challenge Works as a STEM Activity

The BYO Fan Launch Challenge is more than a steady-hand game. It teaches basic electronics and circuit building as you connect the power source, the wire maze, and the fan motor. Kids learn cause and effect: when the hook touches the maze, the circuit closes, and the fan spins.

Because all parts are compatible with other major brick brands, you can integrate it into existing builds or modify the maze layout for extra difficulty. This makes it a flexible project for home, classroom, or playdates.

What You Need Before You Start

The set includes the wavy wire maze, hook, fan, and circuit components. You'll need 3 AA batteries (not included) and a small Phillips-head screwdriver for the battery compartment. A steady surface and good lighting help too.

If you're using bricks from other brands, check compatibility first—the set is designed to work with major brick brands, but ensure the pieces fit snugly.

Step-by-Step Build Guide

  1. Unpack and identify parts: Lay out all pieces: the wavy wire maze, hook, fan, circuit blocks, and connectors. Confirm you have the battery box and motor block. If any part is missing, contact support before starting. Check for all parts first to avoid mid-build frustration.
  2. Build the base structure: Using the brick-compatible pieces, construct a stable base that holds the wavy wire maze upright. Ensure the base is flat and won't tip over during play. Common mistake: an unstable base causes the maze to move, making the game too easy or too hard. A stable base is key to a fair challenge.
  3. Connect the circuit: Attach the battery box to the motor block and the wire maze using the provided connectors. Follow the diagram in the manual to ensure correct polarity. Common mistake: reversing the battery polarity can prevent the fan from spinning. Double-check the battery orientation before closing the compartment.
  4. Insert batteries and test: Insert 3 AA batteries into the battery box. Turn on the switch and touch the hook to the maze to test if the fan launches. If nothing happens, check the battery connections and the circuit path. Test the circuit before playing; a quick touch should trigger the fan.
  5. Play and adjust difficulty: Start with the hook at one end and move it through the maze without touching. If it's too easy, you can bend the maze slightly (if flexible) or add more bricks to create a longer path. If it's too hard, straighten the maze a bit. Adjust the maze to match the player's skill level.

Product Facts

  • BYO Fan Launch Challenge: The BYO Fan Launch Challenge includes a wavy wire maze, a hook, and a fan that launches when the hook touches the maze. This gives you a complete steady-hand game in one set, so you don't need extra parts beyond batteries.
