Like all
kids, grandsons John and Andrew really enjoy playing with magnets. Even very
young children realize that a magnet has the mysterious ability to influence most metal objects (except brass, etc.) or other magnets without touching
them! That’s a superpower
enjoyed mainly by individuals that wear tights and flit from building to
building.
Kids keep
quiet about this mysterious power because they don’t yet have a vocabulary for
asking questions. Later, a science teacher will tell them about ‘contact’
forces and ‘forces that act at a distance’ but by that time, the mystery of a
magnet, met at a young age, has been long forgotten.
Even the
fact that their Androids and iPhones pluck electromagnetic
waves out of thin air and put them in touch with someone ‘at a distance’ isn’t
viewed as mystery. It just is.
Here’s a
simple magnetic device I designed for our grand kids and one that all kids will
find easy to put together and fun to use. You don’t need much stuff and
everything is sealed in a bottle so there’s no mess to clean up.
Materials:
From Radio Shack
Round Ceramic Magnets (5-Pack) $3.19 Catalog #: 64-1888
Duct tape
Clear plastic bottle
Paper clips
Have the kids
• wash
the bottle with warm, soapy water, rinse, and let dry
• empty
a box of paper clips into the bottle
• set
two or three of the magnets on the open, top of the bottle
• tape
the magnets to the top of the bottle
That's it!
By shaking the bottle, kids can create hanging paper clip structures. The problem I set the grand kids was to create a chain of paper clips from the top to the bottom of the bottle. It isn't difficult to do and sometimes the chain is thick, sometimes thin. The following picture shows such a chain.
