Impressed by the many benefits Sport Stacking offers, Nan Chiau High invited Crazy-Cups to conduct mass stacking sessions for their lower secondary students.  With each session having about 340 students, these were definitely the largest gatherings of stackers learning sport stacking together in Singapore!  The students thoroughly enjoyed the sessions, with 51.2% of them rated the Crazy-Cups sessions as Excellent and another 42.8% rated us as Good in the feedback survey!
