Question 23 Sid went to a circus show along with his parents. There he saw an item named “globe of death”, where he saw a person riding a motor cycle moving in vertical circles inside the globe. Sid was amazed because the motorcyclist did not fall even he was upside down at the upper part of his vertical loop inside the globe of death.
