The Physics students’ club, Hiukkanen, built a transportable sauna in the summer ’97. It has been present in several happenings ever since. These photos are taken in front of TUT’s Konetalo during the new students’ fair and at Senaatintori during the Teekkaritempaus. Since 1997 it has been rebuilt and upgraded. The sauna is reported to fit up to 37 people, and hosts a tarzan-yell challenge every year.
