Exploratorium: Science Snacks: Cylindrical Mirror
In this investigation, see yourself as others see you by using a cylindrical mirror instead of a flat mirror.
Exploratorium
Exploratorium: Science Snacks: Depth Spinner
Observe adaptation and perception in the activity. This activity will have students watching a continuously rotation spiral to see what happens as you watch it and then look away.
Exploratorium
Exploratorium: Science Snacks: Designer Ears
Why do animals' ears all look different? In this activity, you will research all shapes and function of ears to create "better" ears.

Exploratorium
Exploratorium: Science Snacks: Downhill Race
An activity that explores how two cylinders that are identical in shape and mass may travel down a hill differently due to how their mass is distributed. Learn how the distribution of mass in an object can affect its translational...
Exploratorium
Exploratorium: Science Snacks: Drawing Board
In this activity, students will create a pendulum that creates beautiful designs with its repetitive patterns. Study the movement of pendulums with these designs.
Exploratorium
Exploratorium: Science Snacks: Duck Into Kaleidoscope
Create hundreds of images of yourself in this activity by making a mirrored kaleidoscope.
Exploratorium
Exploratorium: Science Snacks: Eddy Currents
An activity exploring eddy currents by having a magnet fall through a metallic and nonmetallic tube.
Exploratorium
Exploratorium: Science Snacks: Electroscope
In this activity, students will build electroscopes from common materials. With their electroscopes, students can then conduct experiments to find out what happens to charged objects.
Exploratorium
Exploratorium: Science Snacks: Fading Dot
An activity with an optical illusion that will have your eyes seeing it and then not seeing it! Learn the science behind what makes the dot on the page "disappear".
Exploratorium
Exploratorium: Science Snacks: Falling Feather
Recreate Galileo famous demonstration to show that a heavy and light weighted object fall at the same acceleration in a vacuum.
Exploratorium
Exploratorium: Science Snacks: Falling Rhythm
