The Topsy Turvey Bottles is a classic magic trick that involves a set of bottles that appear to defy gravity. Here’s an explanation of how the trick is typically performed:

1. Setup: The magician starts with a set of two bottles, typically transparent plastic or glass. One bottle is taller than the other. Each bottle has a cap or lid.
2. Visible demonstration: The magician begins by showing the audience that one bottle is empty, and the other is filled with liquid. They demonstrate this by pouring liquid from one bottle to the other, allowing the audience to see the liquid transfer.
3. Misdirection: The magician then performs a series of movements and gestures, diverting the audience’s attention. This can involve waving their hand or a magic wand over the bottles, using theatrical gestures or patter, or introducing a cloth or scarf to cover the bottles momentarily.
4. Bottle switch: During the misdirection, the magician secretly switches the positions of the bottles. The empty bottle is placed on top of the filled bottle, creating the illusion that the liquid is defying gravity.
5. Reveal: After the misdirection, the magician removes the cloth or scarf to show that the bottles have seemingly switched positions. The bottle that was previously empty is now seen to be full of liquid, while the bottle that was filled is now empty.
6. Repeat: The magician may repeat the sequence, switching the bottles back to their original positions and demonstrating that the liquid can once again be poured from one bottle to the other.

The Topsy Turvey Bottles trick relies on the use of specially constructed bottles that allow for the secret switch. The magician’s performance skills, misdirection, and timing play a crucial role in creating the illusion of the bottles defying gravity.
