Disc Launcher

Flywheel

A flywheel is a mechanical device that stores rotational energy. Your Disc Launcher uses the rotational energy (spin) of the flywheel to launch its discs. When a disc touches the flywheel, the flywheel gives some of its stored energy to the disc.

Frequently Asked Questions

VIEW MORE FAQS

Can kids build and play with the toys on their own? Is it difficult?

Ok that’s two questions, but here goes. We design each toy to be a little bit challenging for kids 8-12+, in the same way a good puzzle is challenging. But ours comes with a step-by-step illustrated instruction booklet along with a video of Mark Rober walking kids through each step. We test with 8-12 year olds extensively and prototype for months to make sure each toy is a smooth and enjoyable build. With the help of the video, the instruction booklet, and a dash of tenacity, tons of kids are nailing it and successfully and independently building and playing with Build Box.

For what age is the build box designed?

CrunchLabs Build Boxes are designed for kids ages 8-12+, but plenty of other kids and adults have enjoyed them too! We know some 30 year olds around here who can’t stop sneak attacking each other with disc launchers. We test every product with third-party testing agencies to ensure the products comply with US and EU safety standards for kids ages 8-years and older. Parents and guardians can gauge the appropriateness for their kids, but we have worked hard to ensure that they’re a blast for the intended age range.

Do I need tools or other materials to complete the projects?

Nope! We think we thought of everything! All the stuff you need to make the toy is included in the Build Box, even batteries. You will need an Internet connection and a kid-safe device to watch the Mark Rober video episode, but you don’t need the video episode to complete the build! In the booklet, we do offer ideas for additional games and challenges that may require other materials – but those are supplemental and not required for the main build and play.

BUT, sometimes in engineering, stuff goes wrong. If on the off chance there are parts missing, go to your account dashboard and visit the webpage for your Build Box. Fill out the form to request missing parts. If you have further questions contact help@crunchlabs.com.

How long does it take to complete a Build Box project?

It depends! We try to make each build 30 to 60 minutes on average for an 8-12 year old. If your kid likes to take a lot of snack breaks , or there’s a pesky sibling, or they can’t stop laughing cause the dog fell off the couch, or they just need to clear their head by running around in circles, they can always come back later to finish.

Can I buy a Build Box individually or just one?

Currently, we don’t offer an option to purchase individual Build Boxes (though that may come down the road). We have crafted MULTIPLE years of engineering fun and learning, so we think a subscription is the best.

Are your products safe?

Of course! We test every product with third-party testing agencies to ensure the products comply with US and EU safety standards for kids ages 8-years and older. The safety standards check to ensure the toy is safe and sturdy for its intended play and that unsafe chemicals haven’t been used in the toy production.
