Techniquest is the science discovery centre in Cardiff Bay where you can launch a rocket, sink an oil rig, move half a ton of granite and still have energy for a spot of stargazing! There are more than 120 interactive exhibits across two floors at this waterfront centre – all ready to give the little grey cells a bit of a work out! The Science Theatre has entertaining shows for the public during weekends and school holidays, and curriculum-linked presentations for schools during term time. Techniquest’s Planetarium has a new digital projector which lets presenters take visitors on a tour of the night sky for the date of their visit. There’s also a fully equipped Laboratory which is used for workshops for schools and public visitors.
