A tower of beams on a low table with a child crouched at eye level, deciding where the next one goes.

Balance Beam Set
Four geometries in eighteen pieces, weighted so that a tower balances or does not, visibly, in front of the child who built it.
Eighteen pieces. 
The moment before it falls.

Every number here is off the drawing rather than off a finished toy. The one rule that is not a target is the 40 mm floor on any part, which clears the small-parts cylinder and does not move.
It is the set that teaches a hand to be slow.
Why it is shaped like that
The pieces are deliberately not forgiving. A set that stands up whatever you do teaches nothing about balance.
Living with it
- The long beam is 240 mm and stores flat, which is worth knowing before you choose a box for it.
- Warm soapy water, and a shelf out of the summer sun.
