Everybody loves bubbles, regardless of age. But why all the bubble wands needs to be flat and bubble always spherical. In today’s project, we will break these stereotypes and build some 3-dimensional bubble wands and learn structural engineering. We'll also make an inverted bubble cube that mimics a tensile structure. These simple demonstrations will introduce basic geometric shapes and complex engineering concepts to kids, visually. Things We Need Plastic straws Pipe cleaners A pair of Scissors Bubble Solution, Homemade or store-bought. Bigmouth bowl or container (not in the picture above) Pyramid Bubble Wand To built this Tetrahedron (Pyramid) Bubble Wand: Cut six straws of 2 inches each. Thread a pipe cleaner through one straw and bend the end of the pipe cleaner to secure it at the end. Then thread two more straws onto the pipe cleaner. Bend the long end of the pipe cleaner back to meet the starting point and twist the two ends around each other. Add two more straw sect...
