Why we LOVE this product!
Three different machines from one set of parts is good value, and each one behaves differently, so kids learn more than following steps. The endless marble run is the kind of build children tinker with long after it's finished.
The candy dispenser adds a playful experiment: which candies survive?
Two things to weigh: it needs the Intro to Circuits Kit, and only one machine can be built at a time.
Description
SKU:
BC1504
The SparkBlocks 3-in-1 Mighty Machines Kit is an add-on project kit for building three motorized machines, one at a time, from the same parts: a marble lifter with an endless marble run, a slow-turning windmill and a candy dispenser.
What's inside
- 330+ building bricks
- 1 high-torque geared motor (N20)
- 2 wire blocks and 1 crossover connector
- Word-free instructions for all three builds
How it works
Build one machine, power it with the battery block from the Intro to Circuits Kit, then take it apart and build the next. The marble lifter carries marbles to the top of a run in a loop; the candy dispenser invites kids to test which candies work and which get crushed.
What kids learn
- Simple machines: lifts, gears and mechanical advantage
- Cause and effect: changing a design and seeing what happens
- Energy transfer: from a motor to moving parts
- Iterating: tinkering to make the marble loop run smoothly
Good to know before you buy
- Needs the Intro to Circuits Kit: this is an add-on build. The battery block and core circuit pieces come in the Intro to Circuits Kit, sold separately.
- Age: SparkBlocks lists its kits for ages 8 and up.
- Marbles and candy: SparkBlocks says to bring your own candy for the dispenser; check the listing for marbles.
- Price: $84.00 at SparkBlocks at the time of writing (US dollars for US visitors).
Who it's for
Intro Kit owners who like machines more than models, and kids who enjoy marble runs and figuring out why something jams.

About
SparkBlocks
SparkBlocks was created by two parents who wanted to make STEM learning more hands-on, accessible, and fun. The idea began in 2021, when founder Mark started exploring how electronic components could be built directly into familiar construction bricks. After years of experimenting with circuits, connections, and designs, he developed a system that lets children bring their building creations to life with real electronics. Co-founder Holden joined in 2024 to help refine the system and bring it to more families.
SparkBlocks combines the creativity of construction play with the excitement of discovering how technology works. Its electronic building blocks connect with LEGO®-compatible bricks and can be used to create projects featuring lights, motors, switches, sensors, and sound. Children can follow visual instructions to build working models, then experiment with their own ideas, learning about circuits, engineering, and problem-solving along the way.
Designed for screen-free play, SparkBlocks encourages children to build, test, troubleshoot, and try again. The reusable components can be rearranged into new creations, allowing the possibilities to grow as a child's confidence and skills develop. By making real electronics tangible and playful, SparkBlocks helps young builders move beyond following instructions to understanding how things work and inventing something of their own.
