Quadruple Bond Acrobatics
Four pairs of students represent quadruple bonding in metal complexes by "forming bonds" with a variety of physical methods involving actions like facing each other while holding hands (sigma bond), touch hands and feet of their partner "above and below" the plane (two pi bonds), touching hands and feet while facing each other (delta bond). This results in a "Twister"-like pile of students resembling the quadruple bonding interaction
