Gravity Car

Ages 5-8

rrrrr rrrrr




Get down with gravity! Engineer a gravity-powered car, then explore the effects of gravitational energy while experimenting with different weights and wheel sizes to get your car movin' and groovin'. Finish off by creating colorful drip paintings — all with a little help from a very big force (gravity)!

Everything needed, from materials to illustrated directions, is included, along with explore!, a bonus play & learn magazine with extra projects and activities!


  • Build a car that runs on gravity power
  • Change the wheels and weight to experiment
  • Use gravity to create art


  • Astronomy
  • Science of Gravity
  • Drip Paintings

    Car enthusiast loved it

    My son loves cars already so adding a science element was awesome! Building the car was his favorite part. The completed projects was such a cool experience!

    Focused in on the project

    This was a great activity to do while being indoors. The range of projects in the crate were very exciting and my son worked on it and played with it for over two hours straight! That's a win in my book.

    Really awesome

    Using the car to make art was a cool project on top of building the car. STEAM projects are now my fave!

    Art and science unite!

    The drip paintings came out really good! Combining scientific topics like astronomony and gravity with art methods made for a great overall STEAM activity.

    Future physicist

    Experimenting with the different weights and wheels was fun and scientific. Maybe he is a future physicist?!

    Loved the fun facts!

    Wow! This was an amazing crate! It was challenging enough for my daughter to wear she focused in and built it all by herelf! I am a huge fan of all the fun facts and educational background information they provide that applies to the project.

    Gravity is cool

    Testing out the different ways gravity was effecting the car made my daughter more interested in physics and how science can be fun!
