Techniquest
Since it opened 1986, the Techniquest Science Discovery Centre, located in Cardiff Bay, has become one of the most visited family attractions in the country, with over 120 hands-on exhibits and a Science theatre to keep children (and inquisitive adults) amused.
A series of fully interactive puzzles bring the weird and wonderful tricks of science to life, along with some mind-blowing optical illusions. Watch objects hover in a vertical wind tunnel; make your own shadow freeze in place; find your way through a complex maze of mirrors; act out a rocket or hot air balloon launch; or test your reflexes through a series of challenges.
There's method behind the madness too - as each installation leaves you desperate for explanations, you'll find yourself soaking up information without even realizing and there's plenty to take in. Learn how the surface tension of bubbles affects their speed in a "˜bubble race'; understand how acoustic design can make a whisper audible from 100 feet away; figure out how an object can roll uphill and experiment with making yourself "˜invisible'. Finally, once your brain is well and truly frazzled, head to the Planetarium, where you can lay back and marvel at the glittering night sky.
