Hot tub mysteriously installed, uninstalled at U of Michigan

The mystery of who installed--then removed--a hot tub from the roof of a building on the University of Michigan campus in Ann Arbor has yet to be solved.

Computer Science and Engineering building spokesman Steven Crang said Friday that a group of students are believed to be the culprits.

Initially reported by the Michigan Daily campus newspaper, the hot tub first was noticed Saturday, had visitors the next two days, and was gone Monday night.

Students called it the Bob and Betty Beyster Bubbler after the couple who donated $15 million to the school. The building is named after them.
