Sparks for Cub Scouts

Adventure requirements your den can finish in one meeting, from one kit, with every scout taking their build home.

Sparks for every rank in the pack

Most packs do not have six full dens. In our own dataset of 13,063 packs nationwide, 41 percent average fewer than three scouts per grade, so a Lion and an Arrow of Light often end up at the same table. Every Spark comes as a Small Group Pack of ten, individually bagged, so you can hand out two different builds in one room and nobody waits. Every scout builds their own, and takes it home.


Lions can build and rebuild towers with Straw Structures, or bring an air-powered creature to life with Monster Mouths.

Tigers can build pathways that guide a ball to its goal with Mazes, or make a kinetic lever creature with Art Machines.‍

Wolves can launch high-flying machines with Flying Machines, or invent a grabbing, extending arm with Linkages.

Bears can hand-crank an illustrated story to life with Screen Machines, or design a spring-driven racer with Wind-Up Vehicles.

Webelos can build a motorized wiggling machine with Strawbots, or engineer a pneumatic grabber with Monster Claws.

Arrow of Light scouts can wire a battery-powered car with Electric Vehicles, build a cam-driven story with Scene Machines, or lead a Drawbots build for a younger den.


Many of these line up with adventure requirements. Where we have done the work to prove the mapping, we publish a free leader guide with a printable sign-off sheet. Straw Structures is the first.

The leader guide for Build It Up, Knock It Down is free and needs no signup.

Made to keep

Sparks are made to create, deconstruct, and re-build. When done, they go home with the scout who made it.
