Pllieay 63PCS Solar System Foam Ball Kit for Space STEM Projects
Product description
If your kid likes hands-on science crafts, this Pllieay 63PCS Solar System Foam Ball Kit is built around a simple idea: unfinished materials + easy-to-paint pieces = a solar system model they can actually make themselves. You get foam spheres in mixed sizes, pigments, and the basic tools needed to assemble a colorful display for school projects or a space-themed corner.
That said, it’s not a “finished model in a box.” It’s closer to an arts-and-crafts kit that happens to teach solar system basics along the way. So the payoff depends a lot on whether your child enjoys painting and assembling rather than just observing.
Key takeaways (what you should know before buying)

This kit includes 12 color pigments, a palette, and 26 mixed-sized polystyrene foam balls, plus toothpick flags, painting brushes, and bamboo sticks. There’s also an introduction of the solar system to support the activity. The foam balls are made from high-density polystyrene and designed with a smooth surface for painting.
The mixed sizes are meant to correspond to different “planet” shapes in a model, so the kit supports an easy visual approach to arrangement and scale concepts—at least at the kid-friendly craft level. If you’re aiming for an educational STEM craft that encourages recognition of how many planets the solar system consists of and how they are arranged, this gives you the core building blocks.
One practical limitation: since it’s unfinished, you’ll likely need to plan for painting time (and some mess). And if you’re expecting highly detailed, realistic space-model materials, this is more of a creative school-craft style kit than a precision science display.



Where it shines in real use
On a typical afternoon, the process is straightforward: choose the foam ball sizes, paint them with the provided acrylic color pigments, let them set, then use bamboo sticks and toothpick flags as support and markers. You can make it more “science” by asking your child to count the planets and map them into the model layout using the kit’s introduction as a guide.
Because the kit includes multiple brushes and a palette, it’s set up for color experimentation rather than a single pass of paint. And the foam being lightweight can make handling and assembling easier for kids who get tired easily with heavier craft pieces.

What you’ll notice about the materials
The foam balls are lightweight high-density polystyrene with a smooth surface meant to paint easily. That’s a good sign for beginners because it reduces frustration—paint doesn’t have to fight a rough texture.
The pigments and sticks are described as kid-safe for use. Bamboo sticks are included for building/attachment, and the toothpick flags can help create simple labels or accents on the model.



Still, keep expectations realistic: foam crafts are forgiving, but they’re not indestructible. If a project is meant to travel to school or be handled frequently, it helps to keep the model stored carefully once it’s assembled.

Who it suits—and who should skip it
Worth considering if you want an educational, back-to-school friendly space craft where kids actively paint and build their own solar system model. It’s also a solid choice if you’re looking for a kit that helps develop hand-eye coordination through drawing/painting on blank foam balls.
It may not be the best choice if your priority is a ready-to-display model without painting steps, or if you need a more durable “long-term museum quality” build. It’s also not a great fit if your child loses interest quickly during the painting and assembly stage—because the creative part is the main event here.



Getting the most from your kit
Start by laying out the foam balls by size so the planet count and arrangement feel less overwhelming. Then do the painting in batches: one color type at a time, so colors don’t get mixed accidentally on the palette. When attaching pieces with bamboo sticks, it helps to aim for a stable base before you fully commit the layout—small adjustments early make the final model look cleaner.
Is it going to replace a more advanced science project? Probably not. But for learning basic solar system recognition through a craft activity, it fits the job.
Is it worth it?
This Pllieay 63PCS Solar System Foam Ball Kit is worth buying if you want a complete, kid-friendly kit for making a solar system model from scratch—especially for school science projects and space-themed crafts. The mix of foam sizes, pigments, brushes, palette, and assembly tools makes it easier to go from blank foam to a finished display without hunting for extra supplies.
You may want to skip it if you’re shopping for a pre-made model, or if you already have your own materials and only need planet pieces. Also, if your child dislikes painting, the “unfinished” nature could be a dealbreaker. Otherwise, it’s the kind of kit that turns a science topic into an activity they can actually build with their own hands.
