Get Ready to be Blown Away with this Exciting Project! You'll be using special blocks, like big metal cylinders attached to the sides of your project, to give it a stable base that's shaped like a perfect square. The foundation is made from these same strong blocks that form squares which are actually cones at the top and have triangular pieces that make up their bases too! To keep your rocket moving in the right direction, you'll need triangles on its side.
