KaBlocks Blast is an exciting version of the best-selling KaBlocks construction set. With KaBlocks Blast, kids can do more than just knock down a structure they've built - they can blow it up! The soft foam blocks are easy to stack into tall, teetering towers on the special building platform. When kids are ready, they jump on the stomp lever to blast the blocks into the air. KaBlocks Blast uses kinetic force rather than air power to blast soft foam blocks even higher - over 6 feet into the air! Now even the littlest three-year-old can create impressive explosions time after time. The included activity guide offers play tips and ideas. This set features the highest quality silicone launch pad, easy to use stomp lever. It improves fine and gross motor skills and encourages creative thinking. 25-piece set Includes 22 Soft Foam Blocks, Stomp Lever, Building Platform, Activity Guide Recommended for 1 or more players, ages 3 and up WARNING: CHOKING HAZARD - Small parts Not for children under 3 years of age Made in China Imported Product Specifications 14 in x 11.25 in x 5.2 in Material & Care Plastic Wipe clean with dry or damp cloth
