Set/2 NEW Unopened Mark Rober Crunch Labs Kits

This set of 2 kits includes the Air Ball and Duck Game kits. My son never opened the boxes so photos are from website (apart from the unopened boxes—which is what you’ll receive).  The Crunch Labs Air Ball kit is the 10th build in the STEM subscription series by former NASA engineer Mark Rober. Designed for kids ages 8 to 13, it teaches hands-on engineering principles and fluid dynamics by letting kids build a launcher that uses the Coandă effect to magically levitate a ball in midair.  The Crunch Labs Duck Game Kit is the 9th STEM toy box in the monthly CrunchLabs Build Box Subscription, designed for kids ages 8 to 12. It is a build-it-yourself carnival-style shooting gallery that teaches children the physics of mechanical energy transfer and automated loops.  WANT 30% OFF THIS ITEM?
