Part science experiment and part fun, model rocket kits take the guesswork out of experimentation with well-designed parts and detailed instructions to guide you through how to build a rocket, step-by-step. That said, not all model rocket kits are the same. Some are designed for the serious builder. Others are rudimentary for beginners. Here’s what to think about before you buy one of these building toys for kids. Here’s what to consider.

Age: If your little ones will be using the model rocket kit, you’ll want to ensure it’s age-appropriate. While some kits have a variety of complicated parts, instructions, and builds, others only require a simple setup that parents can help with. Before you buy your kit, check the age parameters on your pick to make sure it suits the little one’s capabilities. Blast off or just build? When you think of a rocket, do you imagine building a complex structure? Or are you more excited about launching it into the sky? Depending on what aspect is your favorite, you might opt for a rocket kit that focuses on one more than the other. While some popular picks are constructed from hundreds of pieces, others are focused on the propelling part of model rocketry. Make sure your model is equipped for flight if that’s essential to you. Some decorative picks and not built for blastoff. Space: Nobody wants to launch their rocket onto a rooftop or over the neighbors’ fence. That’s why you should consider the space you have to move forward with experiments. Check the model kit product description to see how far your rocket launches. If you don’t have a yard to shoot into, you can always launch at a park or nearby open space. Safety features: Most model rocket kits are equipped with the essential safety features you need to keep users safe. But some options are more kid-proofed than others. Some rockets are built with foam to prevent any bumps or bruises, while others have detailed instructions to help you follow along with your kids’ experiments. For children below the age of 5, we recommend steering clear of any small parts that can easily get lost (or swallowed).
