SpillNot
An inexpensive demonstration to
intrigue students and challenge their
analytical powers! The design of this
cup holder uses the principles of
Newtonian physics to keep the liquid
in the container. The flexible handle
and the location of the suspension
point above the center of the tray,
ensure the forces on the liquid are
always directed towards the supporting
tray, even when the tray is in
motion. The sideways forces that are
usually responsible for spills are not
transmitted to the tray by the flexible
handle, and the radial forces generated
during swinging motion only
pin the liquid into the container more
firmly. Includes activity guide. 4-3⁄8"
dia. x 8" H (excluding handle). Grades
7-12. Sh. wt. 0.38 lbs.
SB48234M — $20.00
Rattleback
The Rattleback is a thin, half-elliptical plastic piece
with a slightly offset center of gravity. This offset
gravity causes the Rattleback to spin in the directional
rotation of choice, usually counterclockwise.
If you attempt to spin the Rattleback in
the clockwise direction, strong preference will
cause the Rattleback to rattle back and forth
after a few rotations, stopping and the reversing
the rotation back to the preferred counterclockwise
direction. Includes 10 Rattlebacks and a
teacher’s guide. Grades 7-12.

Happy/Sad Ball Kit
Two rubber balls that look, feel, and
squeeze the same — but try bouncing
them! These intriguing inelastic and elastic
collision balls are popularly called “happy
and sad.” One ball rebounds normally
while the other is as bounceless as a
piece of clay! Instructions included.

Energy and Its Sources
Ideal for getting students
to think about how we use
energy, explore its sources,
and analyze the costs and
benefits of each energy
source. Provides factual
information and
promotes general discussion
about energy and its
impact on the environment.
Players will respond to questions
relating to the specific
energy sources. Both renewable
and nonrenewable
energy sources are discussed,
including hydropower, solar,
wind, biomass, geothermal,
coal, oil, natural gas, and
nuclear power. Each card
includes additional information.
Includes 60 question
cards, reproducible study
guide, and instructions for four different activities/games. Meets National Science
Education Content Standard D. Grades 6-12.
