More than 70 students unveiled themselves last Friday on Francis Quadrangle.
MU's six secret honor societies introduced their initiates to the public at the 71st Tap Day.
"We probably had a crowd of well over 600 people in attendance throughout the ceremony," said Andrew Johnston, Tap Day coordinator. "I would attribute the larger-than-usual crowd to a combination of the outstanding weather we had, increased advertising and the new time."
The Tap Day ceremony began this year at 2 p.m. for the first time, Johnston said.
Participants said they were grateful for the nice weather.
"Last year was one of the four times I have heard of that Tap Day had to take place indoors," Johnston said. "It actually snowed last year, so we were glad to have the fantastic weather we did this year."
Many curious students stopped to ask about Tap Day and watch part of the ceremony.
"How can you not be intrigued by a mass of people wearing different-colored hoods?" asked Jessie Schaefer, an MU junior. "I had no idea this even existed, but it seems like a pretty great honor."
The bulk of the 1 1/2-hour program was devoted to the introduction and unveiling of the honor society initiates.
Although the six honor societies share the same Tap Day, they each have distinguishing characteristics.
QEBH, the oldest honor society at MU, celebrated its 100th anniversary this year.

Unlike other societies, the LSV members introduced at Tap Day participated in secret meetings throughout the year. Friday was the first time the members were publicly recognized as members of the society.
