How To Make A Can "Walk"

Place an empty aluminum can on its side on the floor. Blow up a balloon and tie a knot in the end. Rub a tissue back and forth on the balloon.
When you put the balloon near the can, the can will start rolling toward the balloon.
How Does It Work?
When you rub the balloon with a tissue, the balloon gets a negative electric charge of several thousand volts. When you put the balloon near the can, electrostatic induction affects the molecules in the metal. The outside of the can gets a positive charge, so it is drawn toward the balloon and starts rolling in that direction. Kindly follow for more awesome tips and tricks. Thanks.
