When it comes to freezing Zooper Doopers, the best orientation is typically vertical. This allows the liquid inside to freeze evenly without any chance of spillage, as the pops are designed to be consumed upright. Freezing them vertically also helps the ice pops to hold their shape better, which can make for a more enjoyable eating experience.

However, if you’re limited on space or if there’s a necessity to stack them due to the freezer’s configuration, you can freeze them horizontally. Just ensure they are placed on a stable surface to prevent leakage. Some people may also use trays or containers to keep them organized if freezing horizontally.

Alternatively, you could freeze them in a different orientation if you have a specific creative method in mind, such as suspending them mid-air or freezing them at an angle, but these methods are less common and may lead to uneven freezing or difficulty removing the pops once they are solidified. In general, for best results, stick to freezing your Zooper Doopers vertically.
