The basic effect is that a glass full of milk visibly diminishes, leaving just a couple of sips at the bottom.
The use of this glass is limited to your imagination. To name a few:
- You can use this glass to vanish milk from a paper cone
- After vanishing in the paper cone, you can also produce a white silk from it
- Holding the glass in your hand, ask a child to hold a straw in his mouth & suck -- the milk diminishes from the glass
- You can make a doll drink the milk, and more!
