Suitcase Gyro
# 1Q50.40

Description: This demo includes a wheel with an internal motorized gyroscope and a suitcase. The wheel may be used alone or placed in the suitcase. When used alone, the wheel tends to stand upright. Hit it on its sides to demonstrate this. When used in the suitcase, ask a student to walk in a CW circle and then in a CCW circle. This suitcase will extend away from the student in one case and toward the student in the other case.

Instructions: There are 3 speeds. To turn on the wheel, press the green button. Each time the button is pressed IN QUICK SUCCESSION, the speed will increase. When the button is pressed again, the wheel turns off. Typically, you will want to run the wheel at the highest speed, so press the green button 3 times in quick succession and then press the button one more time to turn it off.
