I have two little builders in my house, both with impressive imaginations and both that work wonders with their little hands. I've found that K'NEX building kits are just the ticket when it comes to finding a great gift for birthdays, or holidays as they can literally spend hours creating, building and having loads of fun with each kit.
The K'NEX Dual Cross Building Set is awesome! They can build six different blaster and target models in one set, including the double chamber Dual Cross Blaster. This blaster fires up to 75 feet and includes K'NEX rods and connectors plus special parts to create more customized blasters. With two blasters chambers, three skull dart holders, two quick fit grips, two preload rings and seven foam darts, the possibilities are endless for them! In addition to the main Dual Cross Blaster, we can download instructions for five alternative blasters and buildable targets.
I can't imagine not getting K'NEX building sets for those special gift giving times during the year!
