    Disc Launcher

    Disc Launcher

    STEM Principle: Flywheel

    SEE MORE

    Box 1

    Disc Launcher

    Flywheel

    A flywheel is a mechanical device that stores rotational energy. Basically, it stores energy by spinning. 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.

    Box 2

    Coin Spinner

    Ratchet

    A ratchet is a device that allows rotation in only one direction. Basically, it only turns one way. It uses special teeth to lock a wheel in place. For the Coin Spinner, when you pull the ratchet back, the teeth lock to store the energy of the rubber band until you release it with the trigger. Then, it transfers stored energy to the coin.

    Box 3

    Trip Wire

    Momentum Transfer

    Momentum transfer is motion passing between objects. Basically, one thing bumps into something else. When the Trip Wire is triggered, the kicker lever swings into the foam ball. The energy transfers from the kicker to the ball, just like kicking a soccer ball. Energy is never lost!

    Drawing Machine

    Linkages

    A linkage uses pivoting bars to guide a machine’s movement. Basically, linkages help things move. The Drawing Machine uses linkages to guide a pen in complex but predictable patterns. The arms are connected to wheels that spin at different speeds. The arms also pivot in difference places, changing where the pen goes.

    Box 5

    Domino Catapult

    Projectile Motion

    Projectile motion is the curved path of a launched object. Basically, it’s the science of tossing stuff. Domino Catapults can launch balls to the same spot over & over due to projectile motion. The motion of a projectile is affected by the angle (trajectory), the force (velocity), and gravity. Keep those the same each time you launch to predict where the ball will land.

    Box 6

    Strobe Light

    Light Refraction

    Light reflection is light hitting an object and then bouncing off of it. Basically, it’s light changing directions. The squirrel animation is made by etching tiny scratches into clear acrylic. The light wants to pass through the acrylic, but when it hits the scratches, it gets reflected out the front. That’s why the squirrels appear to be glowing!

    Box 7

    Mirror Bank

    Mirrors

    Mirrors are smooth surfaces that reflect a clear image. Basically, it’s light changing directions. Your Mirror Bank uses the reflective surface of a mirror to create an illusion of an empty box. The box is only half empty, but because the mirror reflects the empty half perfectly, your eye is tricked into seeing one entirely empty box.

    Boomerang Car

    Worm Gear

    A worm drive is a gear that changes the axis of rotation 90°. Basically, it’s a gear that turns a corner. Worm drives are often used to change the orientation of gear. Notice that the Boomerang Car uses a worm drive to flip vertical rotation from the motor into horizontal rotation of the red & blue switch. As a result, the Boomerang Car’s motor, wheels, and switch all move as one.

    Duck Game

    Belts

    A belt is a loop of material used to carry objects or transfer energy. Basically, belts move stuff along. The belt on your Duck Game carries the ducks in an endless loop. The rollers drive the belt forward, bringing the ducks along for the ride...

    Box 10

    Air Ball

    Coanda Effect

    The Coanda Effect is the tendency of air to follow an object's curvature. Basically, air can wrap around things like a net. The Air Ball game takes advantage of this effect. As the ball enters the airstream, air “wraps” around the ball suspending it in a bubble of air pressure. That bubble of pressure acts like a magnet and keeps the ball centered in the stream.

    Box 11

    Airplane Launcher

    Springs

    A spring stores mechanical energy through elastic deformation. Basically, springs store energy by stretching. The spring in your Airplane Launcher stores energy when you pull your string back and releases energy when you let it go. Your spring returns to its original shape after being stretched due to elastic deformation.

    Box 12

    Rocket Revolver

    Compressed Air

    Compressed air holds a greater pressure than the atmosphere. Basically, it’s tightly-packed air. The Rocket Revolver is powered by compressed air. When you stomp the pump, you're pressurizing the air inside. That air wants to escape back into the lower-pressure atmosphere. The only way for the air to escape back into the atmosphere is by shooting the rocket out of the way.

    How It Works

    Frequently Asked Questions

    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.

    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.

    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.  

    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.

    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.

    If you want to be the first to hear about what we’ve got in store, join our mailing list!

    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.

    Don’t Just Take Our Word For it!

    Best gift! He had the box open and was building within moments of receiving it. Then he showed his siblings and his neighborhood friends just how cool it was!

      Broken Peices

      I was so happy to get this crunch lab build box except two of the black O-rings were broken. Is there any chance you could send me an extra bag of black rings? Sincerely Sam Kay. PS thank you for the crunch. Labs build box.

      Not just for kids

      Crunch lab day is a favorite at our house! We gave my father a subscription for Christmas. While his eyes and memory fail him, this retired engineer loves the time spent with his grandchildren. They narrate for him while they build, and he teaches them about tension, friction, etc. It is the most engaged we see him all month.

      Launcher

      We got our first box today! He was so excited! He loves watching the YouTube videos. He is 11 and it was easy for him to follow along with video and put the launcher together. He is so proud of himself! Perfect for homeschoolers ! Can't wait till the next box!
