About
Techniquest is Wales's premier science discovery centre located in Cardiff Bay, offering over 120 hands-on interactive exhibits that make science accessible, engaging, and fun for visitors of all ages. Established in 1986 and relocated to a purpose-built facility in Cardiff Bay in 1995, Techniquest pioneered the interactive science centre model in Wales, inspiring curiosity and scientific understanding through direct experimentation rather than passive observation.
The centre's philosophy emphasizes learning through play, discovery, and personal investigation, with exhibits designed to be touched, operated, and explored freely.
Visitors can investigate fundamental scientific principles across physics, chemistry, biology, mathematics, engineering, and technology through exhibits ranging from simple mechanical devices to complex optical illusions, from biology demonstrations to engineering challenges.
The Science Theatre hosts live science shows where enthusiastic presenters perform spectacular demonstrations involving fire, liquid nitrogen, electricity, chemistry reactions, and physics principles, making abstract concepts visible and memorable through dramatic experiments. The Planetarium offers immersive shows exploring astronomy, space exploration, cosmology, and Earth sciences under a full-dome digital projection system that transports audiences from Cardiff Bay to distant galaxies.
Techniquest serves multiple audiences: families seeking educational entertainment, school groups participating in curriculum-linked workshops, young children discovering cause-and-effect through play, and adults rekindling curiosity about how the world works. The centre plays a vital role in Wales's science education ecosystem, making STEM subjects accessible beyond formal education, particularly for communities where science opportunities are limited.
With exhibits constantly updated and refreshed, multiple daily science shows, planetarium programs, and special events, Techniquest offers experiences that combine education with entertainment, demonstrating that science is not abstract textbook knowledge but observable, understandable, and exciting phenomena anyone can investigate.

Highlights
Science Theatre Live Shows
The Science Theatre hosts spectacular live science demonstrations performed by enthusiastic presenters who bring physics, chemistry, and biology to life through dramatic experiments and interactive participation. Shows feature spectacular demonstrations with liquid nitrogen freezing objects instantly at -196°C, electrical phenomena including Van de Graaff generators creating lightning-like sparks and making hair stand on end, fire and combustion showing rapid oxidation and energy release, chemistry reactions producing colorful changes and surprising results, and physics demonstrations revealing forces, motion, and energy principles.
Presenters engage audiences through humor, storytelling, and invitation to participate, selecting volunteers to assist with experiments and encouraging questions.
Each show explores scientific themes in accessible ways, explaining the underlying principles while creating memorable visual and sensory experiences. The theatre presentations make abstract scientific concepts concrete and observable, showing that science is not just equations and textbooks but dramatic real-world phenomena.
Regular shows throughout the day mean visitors can time their visit to catch performances.
The Science Theatre is particularly popular with school groups and families, as children remember the spectacular experiments long after forgetting traditional lessons.
Planetarium Shows
The Planetarium features a full-dome digital projection system offering immersive shows exploring astronomy, space exploration, planetary science, and cosmology. Audiences recline in comfortable seating while the dome surrounds them with 360-degree imagery, creating sensation of traveling through space, visiting distant planets, witnessing cosmic phenomena, or exploring Earth from orbit.
Shows are tailored for different age groups from early years programs introducing basic astronomy concepts through family shows exploring solar system and beyond to advanced programs discussing black holes, galaxy formation, and cosmology.
The digital system allows real-time navigation through three-dimensional space, zooming from Earth to distant galaxies while explaining cosmic scales that challenge human comprehension. Programs change regularly, covering topics including the night sky visible from Wales, navigating using stars, life cycles of stars, exoplanet discovery, Mars exploration missions, and the search for extraterrestrial life.
The planetarium complements the hands-on exhibits by addressing subjects difficult to explore through physical interaction, making the vast cosmos accessible through visualization.
The immersive experience inspires wonder and curiosity about our place in the universe.
Interactive Exhibits Floor
Over 120 hands-on exhibits fill the main exhibition space, inviting visitors to touch, operate, experiment, and discover scientific principles through direct interaction. Exhibits cover diverse topics: physics exhibits demonstrate forces, motion, sound, light, electricity, and magnetism through pulleys, levers, optical illusions, sound waves, and electrical circuits; biology exhibits explore human anatomy, senses, health, and living systems; engineering challenges invite building structures, testing designs, and solving problems; mathematics exhibits reveal patterns, shapes, and numerical relationships; technology exhibits demonstrate coding, robotics, and digital systems.
Each exhibit includes simple explanations encouraging experimentation rather than prescribing specific activities.
Visitors learn through trial and error, observation, and discovering cause-and-effect relationships.
The floor layout encourages free exploration with exhibits grouped thematically but accessible in any order. Favorites include a giant soap bubble exhibit where visitors can create enormous bubbles, optical illusions challenging perception, electricity generators powering light bulbs through pedaling, and shadow walls capturing silhouettes.
The hands-on approach recognizes that active engagement creates deeper understanding than passive observation, making Techniquest especially effective for kinesthetic learners and young children who learn through doing.
Discovery Room for Young Children
