Quick answer

Fill each cavity of the Blue Balls Penis Ice Cube Tray with boiled-then-cooled water, freeze flat for at least six hours, and dip the tray base in warm water for a few seconds before flexing cubes out. That routine gives you clearer, better-shaped novelty ice for bachelor party drinks, bachelorette drink ice, and adult party ice ideas.

Why these trays need a different freezing routine

Standard ice cube trays are forgiving: a little cloudiness or a broken corner rarely matters. A penis shaped ice cube is judged on silhouette, so the two common failure points are trapped air and off-center freezing. The Blue Balls tray makes small 8-cube batches, which means you can test one tray before committing freezer space to a whole party's worth.

The tray's playful shape also makes it a conversation piece, so plan where it will sit. A tray that is visibly a novelty ice cube tray works best on a bar cart or drink station, not buried in a cooler where the shapes get lost.

Water, timing, and the trade-offs of clear ice

Boiling water and letting it cool before filling reduces dissolved air, which is the main reason homemade cubes turn cloudy. It is not a guarantee of crystal clarity, and it adds a step, so decide whether shape or speed matters more for your event. For a small batch, the extra few minutes are usually worth it.

Freezing time depends on your freezer and how full the tray is. The safe checkpoint is that cubes should feel solid all the way through and release without slush in the center. If you are short on time, freeze the tray flat on a level shelf rather than stacking anything on top, and start earlier than you think you need to.

When novelty ice is the wrong choice

Shaped cubes have more surface area and can melt faster than large blocks, so they suit punch bowls, cocktail pitchers, and short drinks better than a slow-sipping whiskey. They also need a clean release, which means a tray that is not overfilled. If your priority is long-lasting chilling rather than a visual gag, use the tray for garnish ice and keep a standard tray for the cooler.

Step-by-step: make and serve novelty party ice

  1. Prep the trays: Rinse both trays with cool water and dry them fully before filling. A damp tray can make cubes stick at the corners. Check that the tray sits flat in your freezer before you commit to filling it.
  2. Use cooled boiled water: Boil water, let it cool to room temperature, then pour into each cavity until just below the rim. Overfilling is the most common mistake because it creates a domed top that breaks when you unmold. Leave a small gap at the top of every cavity.
  3. Freeze flat and undisturbed: Place the tray on a level shelf and leave it for at least six hours, or overnight. Do not stack items on top, and avoid moving the tray while the water is still liquid. Test one cube for solidity before you plan the rest of the batch.
  4. Release with a warm-water dip: Dip the underside of the tray in a shallow bowl of warm water for five to ten seconds, then flex the tray gently over a bowl. Do not twist hard or use hot water directly on the cubes. If cubes resist, dip again briefly rather than forcing them.
  5. Store and serve: Transfer released cubes to a freezer bag or lidded container and return them to the freezer. Serve them in clear drinks or a punch bowl where the shape is visible, and keep a spoon nearby so guests can fish them out. Keep a separate standard tray for drinks where shape does not matter.
