- wine glass
- marble or spherical object
- second glass or cup
The challenge is to place a marble into a container while only touching the wine glass. The player cannot touch anything else with their hands!
When setting up this experiment or challenge, the marble can be anything spherical that can easily fit inside of the wine glass. The glass does have to be a wine glass or something similar in shape. The glass has to have an outward curve, meaning the rim of the glass needs to be smaller then the glass itself.
