This large, charming museum inside a late-19th century tram depot features multiple permanent and temporary exhibits at any given time. Usually full of old trams and trolleys, these have recently been moved to the museum's new main branch (under construction) to make room for more rotating exhibits here. What you'll currently find is the 'It's So Simple' interactive educational exhibit full of math and logic puzzles, brainteasers, basic mechanics and future technologies like virtual reality; 'More Light!', an exhibition devoted to lightbulbs and street lamps; and the Classics of Technology mini-exhibit series focusing mostly on telecommunication. Outside you'll also find the small, seasonal 'Garden of New Words' - basically a playground for 3-5 year olds (open April to mid-November). More fun than it sounds and recommended for families, check their website to see what else is on.
