Solve tasks to find hidden Geo point coordinates


Science Centre AHHAA offers science, interesting activities, adventure, useful skills and fun time. Most of the exhibits are 'hands-on', so you can try and feel everything yourself. More than 3 million people of different ages have already visited our exhibitions and other science events. AHHAA was established as a special project of the University of Tartu on 1st September 1997.In 2011, AHHAA’s brand new building was opened in the centre of Tartu. New centre has three exhibition halls on 3, 000 m2. There is also 4D Adventure Cinema in Lõunakeskus Shopping Centre.  
In the Hall of Technology you can ride a bicycle on a rope, feel free fall, experience weightlessness, take a photo of yourself with an exploding balloon, record your shadow on the wall and what more. Here is also the first demo-centre of electric cars in Estonia where visitors can compare electric engines with internal combustion engines. Its main exhibit is an interactive electric car simulator, which allows you to simulate a car ride by operating the steering wheel, pedals, gear box and various switches. A realistic image that changes with your every action will appear on the windscreen. There are also Nissan Leaf and Mitsubishi-MiEV that the visitors can drive. In the Hall of Technology there is another exhibition called 'Aha, Cubed' and it is all about maths. This makes easily clear how the Pythagorean theorem works, how large is one cubic metre, what is a Monkey Calculator and how the length of the pendulum effects its amplitude. There are 23 exhibits on display.
In the Hall of Nature you can see an anthill. This is probably the only place in the world where everyday life of 20,000 wood ants can be studied inside the building. There is also a 6,000-litre aquarium in the hall with the fish and corals from the Red Sea and if you are lucky enough, you may see a chicken hatching from an egg right in front of your eyes. The chicken house consists of two parts: an incubator and a farming part. Every day four eggs, which have been kept in the lab's hatching room in 38-degree warmth in the moist air for 20 days, are put into the incubator.

In the water world exhibition area you can check out fungi and mould, fog machine, water printer, make tornadoes, shoot a water cannon, construct working plumbing system and study the models of Estonian birds.
In the Hall of Temporary Exhibitions there is a Shanghai house, which tests human brain and perception with its sloping walls and floor. In addition to three exhibition venues, all visitors can see an extraordinary collection - the medicine collections of Tartu University's Faculty of Medicine, which exhibits date back as far as 1803. The exhibition shows you the human body from inside, the healthy organs and ones with problems.
Inside the silver sphere on the roof of the centre is a planetarium, which holds the Guinness World Record. You can travel through time and space, see over 5 million stars, planets and galaxies.
Even the lavatories in the centre are educational, because you can check how much water you use when washing hands. But there is more: you can have an adventure in the labyrinth of mirrors, analyse your life in 5 meditation cocoons, to be a pilot in the flight simulator, and check how much energy the wind turbine with solar panels in front of the house produces.
There is also a viewing platform at the top of nearby shopping Centre 'Plasku', which gives an opportunity to see the centre of Tartu at the height of 50 metres.
