Wacław Sierpiński is the name of a Polish mathematician famous for extensively describing a certain type of self-similar triangle, which means it's not only a triangle made out of other triangles but the drawing pattern repeats independently of the scale. This is true not only in 2 dimensions but also in 3 dimensions, where instead of a Sierpinski triangle you have a Sierpinski pyramid.
Building a Sierpinski Pyramid with Strawbees can be done individually but we recommend working as a group to assemble and connect tetrahedrons. You can make a much bigger and interesting construction as a team.
A Sierpinski Pyramid is made entirely of self-similar arrangements of tetrahedrons
