INTRODUCTION
Action & Reaction is a complete kit allowing you to build plenty of fun circuits and experiment – through
trial and error. In other words, the action and reaction principle!
FUNCTIONAL ELEMENTS AND CIRCUITS
The components of this toy are modular, which means that you can t them together in various ways. Follow
the instructions of the A3 sheet supplied with the toy, you will learn how to combine the components
together and assemble the most important functional elements which you can use to obtain the chain-
reaction eects to be inserted along the various points of the circuit. After completing these “exercises”,
you can start assembling the 6 circuits proposed below, which have dierent levels of complexity. Unleash
your imagination and have fun nding new and fun ways to combine the elements and create new and
thrilling chain reactions!
CONTRAPTIONS
Some of the tracks illustrated below are special, as they
will introduce you to the concept of contraption. This
idea, invented in the early 20th century by the ingenious
imagination of cartoonist Rube Goldberg, consists of
creating “household” mechanisms in which an element’s
movement triggers seemingly impossible eects and
ordinary objects, such as boxes, plastic cups or pencils,
can become an integral part of complicated and fun chain
reactions that are only limited by your imagination! In
addition to the routes proposed below, therefore, you can
create “mixed” routes by combining the toy’s elements
with household objects.

SAFETY TIPS
WARNING: Do not aim at eyes or face.
NOTE: the models cannot be constructed
simultaneously.
Warning: when you build the routes, follow
the advice given in the instructions and do not
force the assembly of components that are not
compatible with one another. Always consult the
list of functional elements supplied with the toy.
Warning: use the balls supplied with the toy
only for the activities suggested in the instruction
manual. Do not use dierent objects. You might
risk getting injured!
