Kids can build a functional catapult and learn the physics that make launching objects through the air possible. The catapult itself only requires 90 of the kit’s 181 pieces, leaving plenty of extra pieces to upgrade and explore new design options. As part of the company's Science Project Series, this kit includes a Lab Sheet to test and record a series of suggested experiments."Our construction system is much more diverse than other products, offering integration with other construction sets (Lego, K'nex, Zoobs, Zomes) as well as with recycled materials (Popsicle sticks, McDonald's straws, egg cartons, water bottles). This offers limitless possibilities for children (and adults) to build structures taller than themselves. [Our products] are not available in the mass-market stores," COO Julie Bell of Uberstix told TDmonthly. The Uberpult received the 2007 Parent to Parent Adding Wisdom Award in both Toys/Games and Educational Products categories. It also received The Toy Man Online 2007 Seal of Approval, Award of Excellence and eChoice Award. Launch date: September 2006.
