ERR News - The popular Ahhaa science center will permanently close the doors on its Tallinn branch this weekend but will open a new affiliate in Pärnu for the summer months. The exhibition center, which uses interactive methods to teach science to youngsters, is set to vacate its premises underneath Tallinn's Freedom Square due to the unsuitable nature of the space as well as a disagreement with the city government, which rents out the rooms. On Saturday, April 27, the center put on a science show that will be free to everyone, while tickets on Sunday, the center's last day in the capital, will cost just one euro instead of the normal five euros. The Pärnu branch, to be open from June until the end of August, will be located in the Port Artur I shopping center. The Science Center Energy, a similar institution, will take over Ahhaa's former space in Tallinn. Ahhaa was established in Tartu in 1997 and opened its smaller Tallinn branch in 2009.
