Question: How can the ball on the right be moved into the container on the left without directly touching the ball, adding any liquids or powders, using any external tools, or blowing air at the ball?
A. Transfer by laying the glass cup flat
B. Transfer by shaking the cup
C. Add water to the container to make it float and then transfer it
D. Generate static electricity through friction and use electrostatic attraction to move it
Clues:
1. The left image shows an initial state with a white ball on a surface, covered by an inverted stemmed glass held by a hand.
2. A second glass, a stemless one, is on the left and contains an orange ball.
3. The right image shows the final state where the white ball is now inside the stemless glass, along with the orange ball.
4. The balls are small, spherical, and appear lightweight, consistent with ping pong balls.
5. The inverted glass has a wide mouth and smooth interior, which would allow a ball to roll around its inner circumference easily.
6. The hand is holding the glass by its base, a grip that facilitates a swirling or shaking motion.
