  Put the bottom and top 

halves of the 

globe onto 

the globe base. Press them 
in securely.

6

   Attach  the 

globe funnel to 

the top of the globe.

7

  Examine the tower assembly. The 

gumballs 

are dispensed from the globe at the top and 
gravity pulls them down the tracks, which 
spiral around the tower.

 

 The globe can be 

rotated around on the top 

of the tower so that the knob and dispenser 
can be positioned above any of the four 
sides. 

 

 There are circular 

pegs on each of the 

four sides of the tower. In the assembly 
instructions, the pegs are referred to from 
the top down. For example, this symbol 

means the second peg from the top: 

2

. To 

attach tracks and other parts to the tower, 
first put the peg through the round part of 
the hole in the track piece, then slide the 
track piece down to lock it in place in the 
narrower part of the hole. 

 

 The 

globe funnel allows you to return 

gumballs to the globe after an experiment.

 

 The next four pages teach you about how 
each track and stunt work, and the physics 
behind each one. Or proceed to the assembly 
steps for the first setup on page 8.
