This sounds like a great project!

Did you want non-electrical ideas? If so, you can make straw rockets:

If you turn the launcher into a straw oboe, you have a "Racket Rocket" where you make a sound as you launch :)

If electrical ideas are required try salt dough/sugar dough circuits with LED and battery.

Hi all,

I'm looking to build/assemble a set of tiny STEM kits, small enough to fit in to a toilet roll core (or a Christmas Cracker if you prefer), and I'm trying to cover an many areas as possible...

hence STEM Craicers (or Crackers)

I look after the MakerDojo workshops in Cork, Ireland where instead of doing a lecture about a topic, we try to start off with a build (where the audience get their fingers on the materials to make something practical, or impractical but interesting) so you can see the science in action as its being explained.

The sessions are intended for parents, rather than their kids so small parts are suitable for adults.

I'm looking to make a set covering lots of different areas for the December workshops, but lead times and all that.

So a Christmas Cracker with a kinder-egg ish kit and instructions with the science behind the "toy". Maybe even a paper hat...

Ideas so far....

Coin-cell battery, tape, LED = torch (yawn), add a drinking straw and its a mini light sword (no TM)

button battery, DC motor, toothbrush head, tape = mini brushbot

button battery, DC motor, 3 markers, tape, roll itself = scribble bot

9V battery, stiff wire on one end, piezoelectric speaker, hook and sort wire at the other = concentration puzzle

AA battery, magnets, wire = homopolar motor / tiny dancer

So...

Any is anyone willing to share ideas for these kit types

Take care,

Will

For the record, we're probably too late for Tom Smith to get them on the shelves this year
