335 ASSORTED PARTS - The K-FORCE Mega Boom Building Set includes 335 K''NEX pieces to use in constructing six different toy blasters and target models. This building set includes K''NEX rods and connectors, plus special parts to create customized blasters: two blaster chambers, three skull dart holders, two quick-fit grips, two preload rings, and seven foam darts.
DOWNLOADABLE INSTRUCTIONS - In addition to the main Mega Boom blaster, you can download instructions for five alternate blasters and buildable targets for added fun. The Mega Boom Building Set is compatible with the entire K-FORCE Build and Blast line. Combine the Mega Boom Building Set with other K''NEX sets to build even bigger!
OFFERS HANDS-ON LEARNING - K''NEX educational models offer proactive opportunities for children to develop their creative juices by building their own dart blaster or toy gun. Get your kids away from the computer screen and let them create mentally stimulating experiences by building something that fascinates them.
PEAK PERFORMANCE - Even though these blasters are designed and created by you using K''NEX rods and connectors, you''ll see no loss in performance or durability! Darts fire up to 75 feet and special rod-locks have been added to ensure the parts stay together, even in the heat of battle!
STEAMaginationTM - This is the connection of STEAM (science, technology, engineering, arts & math) with a child''s natural curiosity and creativity, and it powers the fun of each and every K''NEX building set. Building with K''NEX puts children on a path to a fundamental understanding of STEAM / STEM subjects.
CUSTOMIZABLE BLASTERS - K-FORCE Build and Blast is the only line of dart blasters that you design, build and fully customize! Specialized parts like quick fit grips and dart launching mechanisms combine with the K''NEX building system to create any blaster that you can imagine.
COMMITMENT TO QUALITY - K''NEX rods and connectors are responsibly made in America at a landfill-free, zero-waste green manufacturing facility in Hatfield, Pennsylvania. We test to the strictest quality and safety standards, ensuring that your child has a successful, trouble-free building experience.
PARTS GUARANTEE - Broken part? Missing part? If you need a replacement for any reason, just give us a call! We''ll get you what you need so that your child can get back to building as soon as possible.
