Form new groups of 2 with someone new who you don't know.
Challenge: Paper Tower ( #3)--High Rise (Option to add wind as ultimate challenge( 15 min).
Build the tallest free-standing tower out of 3 pieces of paper and a meter of tape, that can survive a high speed fan storm and support the weight of a baseball or tennis ball, secured at the highest point of the tower. The fuzz of the tennis ball must be the highest point of the tower.
Towers were outstanding! Many withstood even a Force 3 wind!
Discussion about how wide base puts the center of gravity well within the structure even with slight tipping.
Moment is an engineering term which measures bending force, and is equal to Force x Length.
Taller towers have a greater bending moment. Having a wide base is efficient, as it provides more material at the point where the bending moment is the greatest.
