Want to make something truly great for yourself and learn something new in the progress? Come and join in one of our numerous workshops that take part every day!

Participation in workshops is free for the science centre ticket holders.

Depending on the number (max. 30 people) and ability of the participants, the workshops usually last for no more than 45 minutes. Workshops are free for visitors of the centre, except for pre-booked workshops for groups. The price for a booked workshop is 3 € per person (with the science centre ticket) or 5 € per person (without the science centre ticket).

Open workshops (i.e. those that have not been previously booked by groups) are subject to availability: there is at least one open workshop every day, where the visitors can sign up by putting their name on the whiteboard in our Hall of Technology. The working language(s) of the workshop is determined by an explainer and is stated on the same whiteboard. AHHAA cannot guarantee the availability of free seats. 

The daily program in AHHAA (available on the front page of our website) is updated every morning.

UNTIL 05.11 1. Caffeine Crystals

Why do coffee and energy drinks give us a boost? What should our daily caffeine intake be (and what happens if we consumed too much)? What is the purpose of caffeine pills and do they have any other ingredients than caffeine? Why are these "other ingredients" necessary, anyway? Come to the workshop and try to find a way to extract pure caffeine from a tiny caffeine pill!

Recommended age: 10 years

2. Enzymes? What are these?

In order to make two molecules react, they need to collide. This requires a significant amount of energy. When molecules are too "lazy" to bounce by themselves, catalysts can help to speed up the chemical reactions. Enzymes are a type of catalysts as well. Where are they found and why do we need them. What is the purpose of catalase, an enzyme that can be found in our cells.

Recommended age: 10 years

3. Blood Under Pressure

Is a heart really heart-shaped? Does somebody actually have blue blood? How many cardiovascular systems do humans have? And why do we need to measure blood pressure - and how do we measure in the first place? Check out the blood pressure monitor and stetoscope and test them as well!

AHHAA's Classics

1. Cabbage Chemistry

Do you know what an indicator is and why do we use them? And can we make indicators out of ordinary everyday object, such as a cabbage? What are the differences between acids and bases and why do we need to know all this? Well, come to the workshop and see for yourself!

10-25 people
Recommended age: 10 years

2. Soap Laboratory

We're surrounded by all kinds of soap, shampoos, washing detergents and so on. How do they work? Let's enter the mysterious and seemingly confusing world of soap chemistry. Find out why you need to add water to soap to make bubbles and how people used to make their own soap at home. All this while constantly being surrounded by the magnificent aromas. Did you know how our sense of smell works? In the end, you too will learn how to make soap - wonderfully bubbly and well-scented!

3. Eye Surgery

We all know pirates wore eyepatches. But not all of them had to cover missing eyes. Realizing that when switching between dark and bright surroundings, eyes need some time to adapt themselves, the pirates started to train their eyes to be able to adapt quicker. Find out how our eyes really work, who has the largest eyes in the world and what does colour blindness really mean. In the end of the workshop, you will get a unique glance inside a real eye.

The workshop is sponsored by Rakvere Lihakombinaat.

4. CSI: DNA extraction

DNA is a recipe to make us who we are. Everything we are - our hair, our eyes, even our brain - is written in our genetic code. All the living things have DNA and some of our genetic information can be really similar. Which one is more closely related to us - a banana or a mosquito? Here, in our laboratory, you will learn how to extract DNA from your own cells, see your own genetic code - and even take it home with you!

10-25 people, up to 30 minutes
Minimum age: 7 years, recommended age: 10 years

5. Chocolate Laboratory

A sweet with a long and interesting history, chocolate has transformed from a bittersweet drink of South American ancient civilization to one of the most beloved foods of the world. Here, you have a chance to make (and eat!) your very own chocolate.

10-25 people, up to 45 minutes
Minimum age: 5 years, recommended age: 7 years

6. Soda Factory

Want to know what is really going on in soft drink factories? And why are there bubbles in soft drinks? Hey, where did soda even come from in the first place? Why don't you join us and explore the history of this fascinating drink, and make some of your own as well!

The workshop is sponsored by A. le Coq

The ECOTRAILS is a project that aims to raise the environmental awareness of the visitors of AHHAA through simple, everyday objects and natural phenomena that we might know, but not be conciously thinking about. In addition to three different learning traces that have been set up in the centre, visitors of AHHAA can also take part in two thematic workshops.

1. Get Smart, Warm Up!

Find out how houses and buildings are being insulated and test your skills and knowledge on budget, planning and construction. Visit a „construction store“, „buy“ the materials and equipment you need and make a play house warm and cosy! Then use a thermal camera to see how successful your construction works have been!

10-25 people,up to 60 minutes
Minimum age: 10 years, recommended age: 10 years

2. The Green Circle

Why do we need to sort our trash and recycle? How do you sort it anyway? What happens to the waste after it's been sorted? How to be(come) a conscious consumer? Come and find out, and see how well-informed and skilful you are!
