Who isn't fascinated by a marble run? Kids love to
watch the tiny ball travel back and forth as it moves through the
tubing. Parents can appreciate the engineering and design that go
into these simple devices. You certainly could buy a marble run
from a store, but you'll have more fun making your own (plus
everybody will learn a thing or two along the way).
This project helps kids think about basic
engineering and mechanical concepts through hands-on experience-see
gravity in action!
Start with a sturdy, large piece of cardboard as
your base, and then raid the recycling bin for discarded paper
towel and toilet paper rolls. Decide on a color scheme for your
marble run and paint each of the components separately using poster
or tempura paints and allow the paint to dry completely. (Or skip
this step and just use the raw cardboard to make your
creation.)
Lay out all the various tubes and think about how
you want to design your marble run. Keep in mind each piece needs
to slope into the next and the marble needs to be able to travel
continuously. Use scissors to cut small openings that will allow
the marble to drop into a lower tube to transition from row to
row.
Don't glue any pieces to the cardboard until you
are sure that your design works (run your marbles through it a few
times to make sure it functions as it should).
An adult can use a sturdy craft glue or a hot glue
gun to attach each component to the cardboard. Once the glue has
dried, check your marble run for any loose spots and apply
additional glue before you get started. Over time, the marble run
may need occasional glue touch-ups.
