Zig & Go Action Reaction Set

Djeco

A wooden chain-reaction construction set from Djeco. Children arrange dominoes, ramps, a see-saw, hammers, spool and rolling marbles into a contraption, then set it off and watch the sequence tumble until a flag flips up at the end. Builds fine motor skills, logical thinking and persistence through trial and error. Includes 27 pieces and a step-by-step guide. Best from around 7 years.
