Quick Answer

To build a bubble machine with Circuit Blox, connect the motor block, fan block, and bubble wand module in a simple series circuit, then dip the wand into the included bubble solution and power it on.

What You Need to Know Before Starting

The Build Your Own Bubble Machine Classroom Set includes all parts and bubble solution needed for a continuous stream of bubbles. The circuit is designed for grades 1-3 and aligns with NGSS requirements, making it ideal for classroom or e-learning use.

A common mistake is connecting the fan block backwards—check the arrow on the block points away from the motor. Also, ensure the bubble wand is fully submerged in solution before starting the motor.

Step-by-Step Build Guide

  1. Step 1: Gather Your Components: Unbox the Build Your Own Bubble Machine Classroom Set and lay out all parts: base board, motor block, fan block, bubble wand module, battery pack, and bubble solution. Check that the battery pack has fresh batteries. Missing any part? Contact Startseite support before proceeding.
  2. Step 2: Build the Base Circuit: Connect the battery pack to the base board. Attach the motor block and fan block in series—the fan block must be placed after the motor block. Press each block firmly until it clicks into place. Common mistake: reversing the fan block direction. The arrow on the fan block must point away from the motor for proper airflow.
  3. Step 3: Attach the Bubble Wand Module: Snap the bubble wand module onto the motor block’s output shaft. Ensure the wand arm is free to rotate and does not touch the base board. If the wand rubs against the base, the motor may stall. Adjust the wand height by adding a spacer block if needed.
  4. Step 4: Add Bubble Solution: Pour the included bubble solution into the shallow tray until it is about 1/2 inch deep. Place the tray under the wand so the wand dips into the solution when it rotates. Too little solution means no bubbles; too much can flood the circuit. Stick to the fill line on the tray.
  5. Step 5: Power On and Test: Turn on the battery pack switch. The motor should spin the wand through the solution, and the fan should blow a stream of bubbles. If no bubbles appear, check that the wand is fully submerged and the fan is blowing toward the wand. If the motor doesn't spin, check all connections and battery polarity. A loose block is the most common fix.
