Another exciting adventure in the life of the twins, Ruth and Rudi.

Accompanied by their grandfather, Professor Nyembezi, they fly to

America to resolve problems with the robots he designed for the new

Station on Mars.

To resolve the problem of controlling the robotic team, the Professor

visits Silicon Valley to obtain special silicon chips to improve the

brain box of each robot. Then the Professor takes the twins to visit the

incredible Walt Disney World and the adjacent Kennedy Space Centre

with the massive space rockets on display. The twins don space suits and

are allowed to sit at the controls of the Space Shuttle.

Ruth and Rudi want to establish a miniature railway track inside the

iMfolozi Game Reserve but this led to their Game Ranger father, Mike,

getting an angry rebuff from the Head Office of the KwaZulu-Natal

Parks Board.

The twins then decide on an alternative site for the miniature steam

railway on land adjacent to their Drakondale School of the Arts and the

Parks Board officials are amazed when the Professor announces that the

railway line is being set up inside what is going to be the world’s largest

aviary. The bird-wire structure will be raised by the Professor’s antimagnetic

units.

The Professor causes gasps of amazement after he equips a redundant

Boeing 707 to fly supported by two of his anti-magnetic units bolted

beneath its wings. This act causes a sensation because it signals an

eventual end to Jet aircraft engines that spew spent fossil fuels across the

sky causing serious global warning.
