It is very common to see water slides at a
water park. Some water slides are spirally-
shaped, so that the riders can feel the
rush of the water flow, as well as the excitement
of spinning! If you pay more attention to the design,
you will notice that there is a cover on every turn. This is
because, due to the movement of inertia, it is very easy to fly off
the edge when sliding into the turn at a very high speed. To have a
cover is to prevent the riders from falling off the slide.
How do you design the track so that balls don’t easily
fall off while rolling on it?

Tony randomly saw a lottery draw show on TV. He noticed that all the lottery
machines were transparent. This way, people could see through the machine
and remove any doubt of cheating.
Tony curiously noted how the numbers that the lottery machine chose all rolled
through a long spiral track. What he couldn’t figure out was what difference
was there between a spiral track and straight track.
One day, while his teacher was introducing
spirals, Tony realized that the benefits of
a spiral design were that they provided
the most efficient use of space, extended
the length of the track, and slowed the
speed at which the ball fell. Tony guessed
the purpose of making lottery machines
transparent was also to let the audiences to
see each number clearly and increase the
suspense of the numbers being revealed!
Kids, do you understand how the spiral
roller is constructed?
Try building it!
