In this revolutionary educational experience, children have the opportunity to be taught by the creator of the theory of relativity himself! Presented as an interactive 3D character, a fun, dancing, quirky Einstein will be their very own personal tutor; guiding them through the various games, helping them when players struggle and telling jokes.

Children are sure to succeed as Einstein steps in with on-screen visual and verbal help when they struggle. - Regular jokes and trivia at different times of the day. - Travel through time by moving the clock hands backwards or forwards and witness the effects of time on the succession of day and night. - ‘Hear’ the effect of time passing: With our time machine, players can speed time up or down and listen to how it affects sound waves. - Learn about different types of clocks. - Learn about rhythms and pendulums: get the timing right or risk throwing poor Albert off the pendulum! - Get familiar with Einstein’s fascinating life story, his hobbies, discoveries and what inspired him to create the theory of relativity that revolutionized modern physics. - Become a relativity expert. - Learn all about the famous twin paradox with an unprecedented simplified and gamified approach. - Control a broken lift and discover the relationship between gravity and time! - Become an astronaut and control a space rocket while exploring the relationship between speed and time! - Break the laws of physics and turn a rocket ship into a black hole! - Audience Q&A: With loads of different questions thrown at Einstein, budding scientists will learn about the philosophy and science of time and finally understand why Einstein’s hair is so messy and why he never wore socks! And much more! All facts and figures have been rigorously checked and researched by subject matter experts to ensure scientific, historical and biographical accuracy.
