What is a Snow Globe Tumbler?

A snow globe tumbler is essentially a double-walled tumbler that has a sealed compartment filled with liquid (usually water or glycerin) and glitter or other small decorative items. When shaken, these items swirl around, mimicking the effect of a snow globe. They are incredibly popular due to their visually appealing aesthetic and customizable nature.

Materials You’ll Need

Before you embark on your snow globe tumbler journey, gather all the necessary materials. This will make the process smoother and more efficient.

* **Double-Walled Tumbler:** This is the foundation of your project. Choose a high-quality tumbler, preferably stainless steel, as it’s durable and safe for containing liquids. Make sure it has a clear outer wall to showcase the snow globe effect. Consider the size and shape that you want. Some tumblers have a completely cylindrical outer wall, while others taper slightly.
* **Epoxy Resin (Two-Part):** Epoxy resin is crucial for sealing the tumbler and creating a watertight barrier. Ensure you purchase a food-safe epoxy resin if the tumbler will be used for beverages. There are many types of epoxy resin, some specifically designed for tumblers with shorter cure times. Consider looking into those if you want to speed up the process.
* **Resin Pigments or Dyes (Optional):** If you want to tint the epoxy resin, use resin pigments or dyes. Mica powders also work well for adding shimmer and iridescence.
* **Glitter:** The heart of your snow globe! Choose a variety of glitter sizes, colors, and shapes. Fine glitter creates a subtle shimmer, while chunky glitter adds more dramatic sparkle. Consider using holographic glitter for a rainbow effect. Avoid using craft glitter which can leach color into the fluid.
* **Distilled Water:** Use distilled water to prevent cloudiness and mineral buildup inside the snow globe chamber. Tap water can contain impurities that will affect the clarity of your tumbler.
* **Glycerin (Vegetable Glycerin):** Glycerin is added to the water to slow the descent of the glitter, creating a more captivating snow globe effect. Start with a small amount and adjust to your liking.
* **Small Figurines, Embellishments, or Charms:** These add personality and uniqueness to your tumbler. Choose items that are waterproof and won’t degrade in liquid. Popular choices include miniature Christmas trees, snowflakes, animals, or custom-made resin charms.
* **Mixing Cups and Stir Sticks:** For accurately measuring and mixing the epoxy resin. Use disposable cups and stir sticks for easy cleanup.
* **Gloves:** Protect your hands from the epoxy resin and other materials. Nitrile gloves are a good option.
* **Mask or Respirator:** When working with epoxy resin, proper ventilation and respiratory protection are essential. Wear a mask or respirator to avoid inhaling fumes.

Step-by-Step Instructions

Now that you have all your materials, let’s get started on creating your snow globe tumbler. Follow these detailed instructions carefully for best results.

Step 1: Prepare the Tumbler

1. **Clean the Tumbler:** Thoroughly clean the outer wall of the tumbler with soap and water. Remove any dirt, grease, or residue. Dry it completely with a clean cloth.
2. **Sand the Surface (Optional):** Lightly sand the area where you will be applying the epoxy resin. This will create a better bond and prevent the epoxy from peeling. Use fine-grit sandpaper (220-grit or higher) and sand in a circular motion. Wipe away any sanding dust with a clean cloth.
3. **Mask Off Areas:** Use painter’s tape to mask off any areas you don’t want to get epoxy on, such as the rim of the tumbler or the bottom. This will ensure a clean and professional finish.

Step 2: Create the Glitter Mixture

1. **Prepare the Liquid:** In a clean container, mix distilled water and glycerin. Start with a ratio of about 80% distilled water and 20% glycerin. You can adjust the ratio later to achieve the desired glitter suspension effect. The more glycerin you add, the slower the glitter will fall.
2. **Add Glitter and Embellishments:** Add your chosen glitter and embellishments to the water and glycerin mixture. Experiment with different combinations to create your desired look. Remember that less is often more. Too much glitter can make the mixture cloudy and obscure the view.
3. **Stir Well:** Gently stir the mixture to ensure the glitter is evenly dispersed. Avoid creating too many air bubbles.

Step 3: Create the Entry Point

There are a few ways to create the opening to add your glitter mixture to the inner chamber. Some tumblers have a plug already installed, others require a small hole to be drilled.

* **If your Tumbler has a Plug:** Remove the plug carefully. You might need a small screwdriver or pick to gently pry it open. Keep the plug in a safe place, as you’ll need it later.
* **If your Tumbler requires a Hole:** Carefully drill a small hole (approximately 1/8 inch in diameter) in the outer wall of the tumbler. Choose a location that is discreet and easy to seal later. Avoid drilling too close to the edge or seam of the tumbler, as this can weaken the structure. Use a drill bit designed for metal or plastic, depending on the tumbler material. Start with a small pilot hole and gradually increase the size to prevent cracking. Wear safety glasses to protect your eyes from debris.

Step 4: Fill the Tumbler

1. **Draw Mixture into Syringe:** Use a syringe or pipette to draw the glitter and water mixture into the syringe.
2. **Inject the Mixture:** Carefully insert the syringe needle into the hole you created and slowly inject the mixture into the space between the inner and outer walls of the tumbler. Avoid overfilling, as this can create pressure and cause leaks. Leave a small air gap at the top to allow for expansion and contraction due to temperature changes.
3. **Remove Air Bubbles (Optional):** If you notice air bubbles trapped in the mixture, you can try gently tapping the tumbler or using a heat gun on low setting to encourage them to rise to the surface. Be careful not to overheat the tumbler, as this can damage it.

Step 5: Seal the Hole

1. **Plug (If Applicable):** If your tumbler has a plug, carefully reinsert it into the hole. Ensure it is securely in place to prevent leaks.
2. **Epoxy Resin (If Drilled Hole):** Prepare a small batch of epoxy resin according to the manufacturer’s instructions. Mix the resin and hardener thoroughly, ensuring there are no streaks or clumps. Use a stir stick to mix, scraping the sides and bottom of the cup to ensure complete mixing.
3. **Apply Epoxy Resin:** Using a stir stick or small brush, carefully apply a small amount of epoxy resin over the hole. Ensure the entire hole is covered and sealed. Avoid getting epoxy on other parts of the tumbler.
4. **UV Resin (Optional):** As an alternative to epoxy resin, you can use UV resin and a UV light to quickly seal the hole. Apply a small amount of UV resin over the hole and cure it under the UV light for the recommended time (usually 1-2 minutes). This creates a very hard and durable seal.

Step 6: Apply the Epoxy Resin Coating (Optional but Recommended)

Applying a coat of epoxy resin to the entire *outside* of the tumbler is highly recommended for several reasons: it seals the glitter area completely making it waterproof, it gives a glossy smooth finish and it allows you to add decorative elements like vinyl decals. This step requires care and patience to ensure a beautiful and even finish.

1. **Prepare the Epoxy Resin:** Measure and mix the two-part epoxy resin according to the manufacturer’s instructions. It’s crucial to follow the instructions precisely, as incorrect ratios can result in a sticky or uncured finish. Typically, this involves mixing equal parts of resin and hardener. Stir slowly and thoroughly for several minutes to avoid introducing air bubbles. Scrape the sides and bottom of the mixing cup to ensure complete mixing.
2. **Tint the Epoxy (Optional):** If you want to add color to the epoxy, add a small amount of resin pigment, dye, or mica powder to the mixed epoxy. Stir well to ensure the color is evenly distributed.
3. **Apply the First Coat:** Pour a small amount of the mixed epoxy onto the tumbler. Using a gloved hand or a foam brush, spread the epoxy evenly over the entire surface, working from top to bottom. Make sure to coat all areas, including the sides and bottom. Apply a thin, even coat to avoid drips and runs. A brush allows for more precision, but a gloved hand can give a smoother finish once you get the hang of it.
4. **Remove Air Bubbles:** Use a heat gun or hair dryer on low setting to gently warm the epoxy. This will help release any trapped air bubbles and create a smoother finish. Hold the heat gun a few inches away from the tumbler and move it slowly and evenly over the surface. Don’t overheat the epoxy, as this can cause it to yellow or bubble. A toothpick or pin can also be used to manually pop any visible air bubbles.
5. **Cure the Epoxy:** Place the tumbler on a level surface or a tumbler turner. Ensure it is perfectly level to prevent the epoxy from pooling on one side. Allow the epoxy to cure for the recommended time (usually 24-72 hours), according to the manufacturer’s instructions. Keep the tumbler in a dust-free environment during the curing process. A clean cardboard box placed over the tumbler can help protect it from dust.
6. **Apply Additional Coats (Optional):** For a thicker, more durable finish, you can apply additional coats of epoxy resin. Repeat steps 3-5, allowing each coat to cure completely before applying the next. Lightly sand the surface between coats with fine-grit sandpaper (400-grit or higher) to create a better bond.

Step 7: Add Decorations (Optional)

1. **Create Your Design:** Use a cutting machine (like Cricut or Silhouette) to create custom decals or monograms from vinyl. You can also use pre-made vinyl stickers or embellishments.
2. **Weed the Vinyl:** If you’re using a cutting machine, carefully weed away the excess vinyl from your design, leaving only the desired image on the backing sheet.
3. **Apply Transfer Tape:** Apply transfer tape over the weeded vinyl design. Use a scraper or squeegee to firmly adhere the vinyl to the transfer tape.
4. **Transfer the Design:** Carefully peel the transfer tape (with the vinyl attached) away from the backing sheet. Position the design on the tumbler where you want it, and then firmly press the transfer tape onto the tumbler. Use a scraper or squeegee to ensure the vinyl adheres to the tumbler surface. Gently peel away the transfer tape, leaving the vinyl design in place.

Step 8: Final Touches

1. **Inspect the Tumbler:** Carefully inspect the entire tumbler for any imperfections, such as drips, runs, or air bubbles. If you find any, you can try sanding them down with fine-grit sandpaper and applying a thin layer of epoxy resin to smooth them out.
2. **Clean the Tumbler:** Once the epoxy is fully cured, clean the tumbler with a soft cloth and mild soap and water. Avoid using harsh chemicals or abrasive cleaners, as these can damage the epoxy finish.

Tips and Tricks for Success
