Probably the most unusual use the pool was ever put to was as a baptismal font.
In July of 1924, the International Bible Students Association held a convention at the Ohio State Fairgrounds. Thousands of delegates from the United States and around the world attended. On the final day, a baptism was held. The convention secured the use of nearby Indianola Park's pool for the occasion.
On Saturday, July 26, 1924, before a crowd numbering more than 10,000, 750 Bible Students were baptized in the shallow end of the pool. The dance pavilion orchestra played hymns for the ceremony. Indianola staff helped people in and out of the pool.
Even with the help of park staff and two clergyman officiating, it took over an hour to complete all the baptisms.
