Follow these step-by-step instructions to build a working bubble machine with Circuit Blox. Learn how to assemble the circuit, add bubble solution, and troubleshoot common issues.
Quick answer
To build your own bubble machine, start with a Circuit Blox kit like the Build Your Own Bubble Machine. Assemble the base, connect the motor and fan blocks, attach the bubble wand, and add solution. Test the circuit before adding bubbles. Most builds take 15–30 minutes.
What you need before you start
Gather your kit and clear a flat, dry workspace. The Build Your Own Bubble Machine includes all necessary parts and bubble solution. For classroom use, the Student Set adds a 30-page teacher guide and aligns with NGSS requirements. If you don't have a kit, you'll need a battery pack, motor, fan, and a bubble wand—but kits simplify assembly and ensure compatibility.
Step-by-step assembly
Follow these steps in order. Each step includes a checkpoint to prevent common mistakes.
Tips for best bubble performance
Use fresh bubble solution and avoid windy areas. If bubbles are small, check that the wand is fully saturated and the fan is spinning freely. For longer runs, consider the Student Set which includes a teacher guide with curriculum connections.
Assembly steps
- Prepare the base: Snap together the base blocks to form a stable platform. Make sure all connections are tight. Checkpoint: The base should not wobble when pressed.
- Attach the motor block: Connect the motor block to the base, aligning the pegs. The motor drives the wand. Common mistake: Forcing the block; it should click easily.
- Add the fan block: Attach the fan block next to the motor. The fan creates airflow to blow bubbles. Checkpoint: Fan blades should spin freely by hand.
- Connect the power source: Snap the battery pack onto the circuit and insert batteries (not included). Common mistake: Inserting batteries backwards; match + and -.
- Attach the bubble wand: Secure the wand to the motor shaft. It should sit just above the solution tray. Checkpoint: Wand spins without hitting the tray.
- Add bubble solution: Pour solution into the tray until the wand can dip. Do not overfill. Common mistake: Spilling solution on electrical parts.
- Test the circuit: Turn on the switch. The motor should spin and the fan should blow air. If nothing happens, check battery orientation and block connections.
