The colorful world of Shrinky Dinks has captivated crafters and hobbyists of all ages. These fascinating plastic sheets can shrink to bountifully small sizes when exposed to heat, turning whimsical drawings into hard plastic charms. However, a common question arises each time crafters gather around their projects: Can I put Shrinky Dinks in the microwave? In this article, we will dive into this topic, exploring the right materials, best practices, and creative ideas for utilizing these delightful crafting products.
What Are Shrinky Dinks?
Before diving into the microwave debate, it’s essential to understand what Shrinky Dinks are and how they work.
The Basics of Shrinky Dinks
Shrinky Dinks are made from a type of polystyrene plastic that is designed to shrink when exposed to heat. Typically, these plastics are available in various forms, including sheets, pre-cut shapes, and even ready-to-color kits. Here’s how they function:
- Artistic Expression: You can draw or color on them using permanent markers, colored pencils, or even inkjet printers.
- Heat Application: When heated, the plastic shrinks to about one-third of its original size—while also thickening and becoming denser.
- Cooling Stage: Once removed from the heat source and allowed to cool, the shrunk piece solidifies, showcasing your artwork in a miniature, durable form.
The Science Behind Shrinkage
The shrinking process is a neat demonstration of thermodynamics. Essentially, when you heat polystyrene, the polymer chains that make up the plastic become energetic and move around more freely, allowing the material to shrink. As the temperature rises, the polymers start to retract back to their original form (before production), leading to the dramatic reduction in size.
Can You Microwave Shrinky Dinks?
Now to the crux of the matter: Can you put Shrinky Dinks in the microwave? The short answer is yes, but with some important considerations and precautions.
Understanding Heat Sources
While the microwave can be an option, it’s crucial to understand how it compares with other heating methods:
-
Oven Method: The most traditional method of using Shrinky Dinks is baking them in an oven. This method usually is preferred because of its more even heat distribution, minimizing the risk of the plastic warping or reacting unpredictably.
-
Microwave Method: Microwaving Shrinky Dinks can work, but it’s not as straightforward. Microwaves heat unevenly, which can cause parts of the plastic to heat too quickly and warp, or potentially even ignite.
How to Safely Use Shrinky Dinks in the Microwave
If you choose to use the microwave for your Shrinky Dinks, there are recommended practices to minimize risks and maximize fun.

Can I put Shrinky Dinks in the microwave?
Yes, you can put Shrinky Dinks in the microwave! Many people are surprised to learn that this popular crafting material can be shrunk using a microwave rather than an oven. The key is to ensure your Shrinky Dinks are made from the right type of plastic, which is typically labeled as “polyolefin.” Before microwaving, make sure to cut them out into the desired shapes and decorate them as you like.
When using the microwave, place your prepared Shrinky Dinks on a microwave-safe plate. It’s recommended to microwave them for 1 to 3 minutes, keeping a close eye on them. The pieces will curl up at first, but don’t worry; they will straighten out as they shrink. Once they flatten out, you can take them out, but allow them a moment to cool before handling, as they can be quite hot!
What happens when you put Shrinky Dinks in the microwave?
When you put Shrinky Dinks in the microwave, the heat causes the plastic to shrink and harden. This reaction occurs because the plastic is made up of a polymer that contracts when heated. As the Shrinky Dinks shrink, they also become thicker and more rigid, transforming from a flexible sheet into a sturdy piece of art or jewelry.
To achieve the best results, it’s important to distribute the pieces evenly on the microwave-safe plate and not overcrowd them. This allows the hot air to circulate properly and helps each piece shrink evenly. If you notice that they are not shrinking correctly, you might need to adjust the time or check if your microwave’s wattage matches the recommendations for Shrinky Dinks.
How long do I microwave Shrinky Dinks?
The ideal microwaving time for Shrinky Dinks is typically between 1 to 3 minutes, depending on the strength of your microwave. It’s wise to start with shorter intervals, as different microwaves can vary significantly in power. Begin with 30 seconds, then check the pieces. If they are still curled or not fully shrunk, you can continue microwaving in 15-30 second increments.
During this process, keep a close watch on the Shrinky Dinks to avoid overheating, which can cause them to warp or become uneven. Once they begin to flatten out and become stable, remove them from the microwave and let them cool down. After cooling, they will be significantly thicker and more durable than before!
Do you need to preheat the microwave for Shrinky Dinks?
No, you do not need to preheat the microwave when using it to shrink Shrinky Dinks. Unlike traditional baking processes where preheating is essential for even cooking, microwaving works differently. The microwave heats the materials from the inside out, so there’s no advantage in preheating.
Simply place your decorated Shrinky Dinks on a microwave-safe plate and start microwaving them for the recommended time. Always monitor their progress, as the absence of preheating means the initial heating phase will occur at the same time as the shrinking process begins. This can lead to faster results, but requires your attention to avoid any mishaps.
Can I use a regular oven instead of a microwave for Shrinky Dinks?
Yes, you can definitely use a regular oven instead of a microwave for Shrinky Dinks, and many crafters prefer this method. To do so, preheat your oven to around 325°F (163°C) and arrange the cut-out Shrinky Dinks on a baking sheet lined with parchment paper. The oven method allows for a more evenly distributed heat, which can help to achieve a consistent shrinkage across all pieces.
Once the oven reaches the desired temperature, place your baking sheet inside and monitor the pieces closely. Typically, Shrinky Dinks will take about 3 to 6 minutes to shrink in the oven. You will see them curl initially, and then they should flatten back out as they finish shrinking. When they are done, carefully remove them from the oven using oven mitts and allow them to cool before handling.
Are there any safety precautions I should take?
Yes, when using either a microwave or an oven for Shrinky Dinks, there are several safety precautions you should take. First, always use microwave-safe or oven-safe materials when preparing your Shrinky Dinks for heating. Avoid using metal containers or utensils in the microwave, as they can cause sparks or damage the appliance. Similarly, when using an oven, ensure that the surface of your baking sheet is stable and secure.
Additionally, be cautious when removing hot Shrinky Dinks from the microwave or oven. Use oven mitts or heat-resistant gloves, as the materials can become quite hot during the shrinking process. Allow both the cooking appliance and the crafts to cool down adequately before attempting to handle or store them to prevent burns or injuries.
Can I reuse Shrinky Dinks after they have shrunk?
Once Shrinky Dinks have been shrunk and set into their final form, they cannot be re-expanded or reused in their shrunken state. The physical properties of the plastic change permanently during the heat process, meaning they retain their smaller, thicker shape once cooled. This is a common question among crafters, as many wish to experiment with their creations after noticing the exciting effects.
However, if you’re looking for versatility, one option is to experiment with multiple batches or to create new designs altogether. Since Shrinky Dinks come in various colors and types, you can continuously create unique pieces without fear of redundancy. Just remember to save your favorite designs, as once they are shrunk, it’s difficult to revert back to the original form!
What type of markers or pens can I use on Shrinky Dinks?
When decorating Shrinky Dinks, it’s essential to use the right type of markers or pens. Permanent markers, colored pencils, and some types of gel pens work well for this purpose. Permanent markers are highly recommended because they can withstand the heating process without smudging or fading. Be sure to select non-toxic varieties, especially if you’re crafting with children.
It’s best to avoid water-based markers, as they may wash away or be too diluted when heat is applied. Additionally, always test your markers on a small piece of Shrinky Dink first if you’re unsure of the outcome. Once you’ve finalized your design, remember that the colors will darken and intensify slightly after shrinking, providing a surprising final touch to your craft!
