Are you a science fiction fan? Then why not visit a real astronomical observatory some kilometers at the south side of Ieper (AstroLAB IRIS, Verbrandemolenstraat 5, 8902 Zillebeke)? They have cool multimedia shows and if weather and twilight circumstances make it possible, you can take a look to the sky with a real telescope. Then you can feel how little you are in the big big universe. A ticket is 130 BLXF per person.
They also have a cyberpub ("THE UNIVERSE") to surf on the Internet. Price: 4,50 Euro per hour. You can visit the astronomical observatory and cyberpub at Friday from 19h30 until 23h30 p.m., or at Sunday from 14h until 18h p.m., or at other times after appointment on telefone ++32(0)57/200.387 (Carl Vandaele; from 13h until 19h p.m. BELGIAN TIME in the week; not present at this number during the weekend and in July).
