Attention: there will be NO box office this evening. At the ball itself, only the few tickets that have already been paid but not yet picked up will be issued at the Lichtenfelsgasse entrance of the town hall starting at 7.45 pm. So it makes no sense to come to the city hall without tickets.
A quick tip: the ticket sale for the 7th Science Ball 2021 will most likely begin on November 11, 2020. Just send an e-mail to firstname.lastname@example.org and be reminded by e-mail alert in November 2020. Have fun.
