Commercial Ferrofluid
Your students will be fascinated as you
demonstrate the unique properties of this
nanoscience material and produce interesting
3-dimensional magnetic sculptures.
Concepts: Nanotechnology, magnetic
properties, colloids vs. solutions.
Note: A magnet is required and available separately.

Ferrofluid Nanotechnology
By: The Flinn Staff
A magnetic liquid, also known as a ferrofluid,
may seem like a space-age concept. That’s
because it is! Now you can prepare a ferrofluid
and demonstrate the concept that was
invented by NASA in the 1960s to control
liquids in space.
Concepts: Ferrimagnetic substances and
magnetic properties, colloids vs. solutions, nanotechnology.
Note: Perform this demonstration in a fume hood or well-ventilated lab.

Ferrofluid Lava Lamp
This scientific twist to the traditional lava lamp involves a tangible
manipulation of the nano-sized magnetic particles suspended in
a liquid—the ferrofluid. Includes three sets of magnets in varying
strengths of low to high. 5" W x 151/2" H.

The Pink Catalyst
By: Jim and Julie Ealy, Retired,
The Peddie School, Hightstown, NJ
Learn how a catalyst works by observing the color
changes of pink cobalt ions. You’ll see the catalyst as it
gets swept up in the oxidation of tartrate by hydrogen
peroxide, changes into a green intermediate, and then
reappears again at the end.
Concepts: Kinetics, catalysts.

AP2084 The Pink Catalyst—Chemical Demonstration Kit $30.53
The ROY G BIV
Clock Reaction
By: Steve Spangler, Regis
University, Denver, CO
Take seven different dry chemical
mixtures and add each to
a separate beaker. Pour a clear
liquid into each beaker. In less than a minute, the large pH change at the end of this
clock reaction causes the seven rainbow colors.
Concepts: Clock reactions, pH indicators, buffers.

AP6280 The ROY G BIV Clock Reaction—Chemical Demonstration Kit $48.97
“Visualizing the Transition State”
Demonstration Model
By: Jeff Fieberg, Centre College, Danville, KY
Demonstrate the properties of the transition state or activated
complex with this unique, colorful demonstration device—a
plastic ball that suddenly switches inside and out when tossed
into the air with just the right amount of spin.
Concepts: Chemical kinetics, transition state theory, activated
complex.

Thionin—The Two-Faced Solution
By: The Flinn Staff
“Elegant” best describes this wonderful demonstration.
A large beaker containing a purple solution is
placed on an overhead projector. Aluminum foil is
placed under the beaker so only half the beaker will
be exposed to direct light.
Concepts: Light-activated reactions, indicators.
