Shrinky Dinks are a fun and easy craft that can be made from recycled plastic. They are a great way to reuse plastic containers that would otherwise end up in landfills. To make Shrinky Dinks, you'll need recycled #6 plastic, which can be found in clear containers from salad bars or takeout containers. It's important to ensure that the plastic is clean and dry before starting. Using permanent markers, decorate the plastic with your desired shapes and designs, then cut them out. Keep in mind that the plastic will shrink to about 1/3 of its original size, so plan accordingly. Place your plastic creations on a sheet pan with parchment paper and bake them in the oven at 325-350 degrees Fahrenheit for about 1-3 minutes. As they bake, you'll see them curl up and then flatten back out. With a bit of creativity, you can turn your Shrinky Dinks into charms, necklaces, zipper pulls, or even custom sewing pins. So, gather your recycled plastic and get ready to unleash your imagination with this retro craft!

What You'll Learn
Using recycled plastic containers
To make shrinky dinks from recycled plastic containers, you will need to use #6 plastic. This type of plastic is typically used to make clear containers that are cheap, lightweight, and easily formed into shapes. You can find them as takeout containers for salads or lids for pans made of aluminum. #6 plastic is also used to make disposable cups and containers for takeout food, but these are not suitable for this project.
Once you have your #6 plastic container, ensure that it is thoroughly cleaned and dried. Then, preheat your oven to 350 degrees Fahrenheit. Cut the plastic into the desired sizes and shapes, keeping in mind that it will shrink to about a third of its original size. If you plan to make a charm, punch a hole in your design before baking. Decorate your plastic cutouts with permanent markers, or use a pencil first if you want a faint guide.
Place your plastic pieces on a sheet pan lined with parchment paper to prevent sticking. You can also use aluminum foil and fold up the edges to prevent slipping. Put the baking sheet on the middle rack of your preheated oven and watch your DIY Shrinky Dinks closely. They will first curl up and then flatten back out. Bake for about 3 minutes, and then for an additional 30 seconds once they have flattened.
It is important to note that #6 plastic, when heated, can release styrene fumes, so ensure proper ventilation during the baking process. Additionally, #6 plastic is known to release toxins when heated, so consider using a toaster oven outdoors and avoid using the toaster for food afterward.

Choosing the right type of plastic
When making Shrinky Dinks from recycled plastic, it is important to choose the right type of plastic to ensure the best results. The most suitable type of plastic for this project is #6 plastic, which is the classification for Polystyrene, commonly known as Styrofoam.
#6 plastic is ideal for Shrinky Dinks because it shrinks down to about one-third of its original size, allowing you to create charms, trinkets, and other creative shapes. This type of plastic can be found in various sources, such as takeout containers, salad containers, deli meat trays, and lids for pans. It is important to look for the #6 stamp on the plastic to ensure you are using the right type.
While Styrofoam is often associated with disposable cups or takeout containers, these are not suitable for this project. Instead, look for clear containers that are lightweight and easily formed into shapes. These containers are typically used for salads or as lids for aluminum pans. By reusing this type of plastic, you can also contribute to environmental sustainability by keeping it out of landfills.
It is worth noting that #1 plastic, commonly found in food containers, is not ideal for Shrinky Dinks as it does not flatten or shrink as effectively as #6 plastic. #1 plastic may turn white, curl, or not shrink much, resulting in less desirable outcomes for your crafts. Therefore, it is crucial to identify the type of plastic before starting your project to ensure optimal results.

Decorating and colouring your design
When decorating and colouring your Shrinky Dinks, it's important to remember that only #6 plastic will shrink correctly. #6 plastic is the classification for Polystyrene, also known as Styrofoam. However, when heated, #6 plastic can release styrene fumes in small amounts, so it's best to do this in a well-ventilated area.
If you're using recycled #6 plastic, you're likely to only find smooth surfaces, so you'll need permanent markers to decorate your Shrinky Dinks. Make sure your plastic is really clean and dry before you start, especially if you're using old takeout containers. You can simply wash them with dish soap and water.
If you want to draw out your design first, you can use a pencil, which will be faint but may be helpful as a guide before you commit to using a marker. You can also use coloured pencils or crayons to decorate your Shrinky Dinks. If you're using a crayon, you might want to lay the sheet on a colouring book page or a printable pattern and draw your design onto the sheet.
If you're planning to make your Shrinky Dinks into charms, you can use a hole punch to make a hole in your design before baking. You can also add jump rings, beads, and cording to make necklaces or beverage markers.

Cutting out your Shrinky Dinks
Firstly, ensure that you have the right type of plastic. Look for #6 plastic, which is the classification for Polystyrene, also known as Styrofoam. This type of plastic is commonly used for takeout containers, salad bar containers, or lids for pans made of aluminum. It is important to note that disposable cups or takeout containers are not suitable, as they are too thin and can be difficult to work with.
Once you have your #6 plastic, make sure it is clean and dry. Give it a good wash with dish soap and water to remove any residue. Then, thoroughly dry the plastic before moving on to the next step.
Now, it's time to get creative and decide on the shapes you want to cut out. You can cut out circles, squares, lightning bolts, or any other shape your imagination can come up with. Keep in mind that the plastic will shrink to about 1/3 of its original size, so plan your sizes accordingly. For example, if you start with a 3-inch-high piece of plastic, it may only be about 1 inch in height when it's finished.
When you're ready to cut, grab a good pair of sharp scissors. You can also use large punches to cut out shapes, especially if you're making simpler designs like hearts. If you're creating more intricate designs, you might want to draw out your design on the plastic first. You can use a pencil to create a faint outline, then go over it with a permanent marker.
Finally, cut out the shapes you've drawn on the plastic. Remember that the plastic will shrink, so you don't have to be too precise. If you're planning to make charms, don't forget to punch a hole in your design before baking.
