## What it does

The patent describes a method for creating a frozen confection by placing a handle into a container of liquid, such as soda or fruit juice, and freezing the mixture until it becomes a solid block. The handle remains embedded in the frozen mass, allowing the user to hold the treat without touching the ice directly. This simple mechanical design allows for a portable, handheld frozen snack that melts slowly while being consumed.

## What it does NOT cover

- Does not cover liquid-based treats that do not utilize a handle or stick for consumption.

## Real-world examples

1. Popsicles
2. Fudgsicles
3. Homemade fruit juice ice pops
