1. and 2. in November 2025 will be filled with a real whirlwind of invention at PROTO, and guests are expected from near and far!

Over the course of two days, there will be amazing performances, you can take part in educational and fun workshops, and see so many exciting things!

The Space Education Center from Cēsis brings a whole exciting activity to the festival: train your reaction speed and memory like a real astronaut, overcome obstacles caused by space debris to make your space mission a success, and build your very own paper rocket and test how far you can fly it!

The AHHAA Science Center brings you two spectacular science performances on both festival days:

Effective interlude

In this performance, you will see the best pleas of AHHAA Science Theater! For example, mystical color reactions, puffs of fog, fireworks and explosions. All this in an educational but fun way!

Chemistry of combustion

What is combustion and what is needed for it? Which materials burn, which don’t? We’ll show you fire rain, liquid oxygen, lots of fierce flames and, most importantly, a bang! Fiery experiences!

• Design and build parachutes for different weights and discuss what needs to be considered when landing on the Moon or Mars.
• Solve the astronaut’s suitcase problem – what to take, what to leave.
• Practice driving a lunar rover and put your creativity to the test.

Step aboard and let your imagination fly – real space exploration and adventures for the whole family await you here!

On the occasion of the Year of the Book, Tallinn TV Tower invites all young inventors to join in the thinking and crafting!
What unites a good inventor and a great book lover? Of course, curiosity, attention, and the ability to notice details – these are the qualities that are needed in our workshop, where we make smart bookmarks from various materials .

A simple item like a bookmark can turn into a real invention if you let your imagination run wild and give new life to materials.
The workshop is a hands-on and creative activity that is suitable for for children from 6 years of age .

All participants will also be welcomed by the TV Tower’s extraterrestrial friend ETI , who will be watching with interest what ideas the young inventors bring to life!

Check out the Solaride II solar car and build a wind car!

Who is it for? For those of all ages

Solaride has been building a solar car in a garage for two years, but now he invites you to build a wind car at the Great Inventors Festival.

In the workshop, there are exciting materials, parts, and tools on the table, from which anyone can assemble a small vehicle. Once the car is ready, it is put to the test with a blower: can the wind car you have built be able to travel a given distance?

Check out one of the most impressive student projects in Estonia – an electric formula created by Formula Student Team Tallinn , which is capable of driving without a driver! This is not just a formula, but a feat of engineering excellence that combines innovation, speed, and precision.

Can you imagine how in 10 months it is possible to build a race-ready formula from scratch that can compete with the world’s top university teams? The car can accelerate from 0-100km/h in under 2.5 seconds and achieve 3G lateral acceleration in a corner. Now you have the opportunity to see with your own eyes how dedication, passion, and talent create something truly extraordinary!

The Three Pigs Science Circles team believes that the scientists and engineers of the future will grow from the children to whom we open the door to the world of science and technology today.

We invite you, brave explorer, to the workshop, where together we will build your first harmonica and invent colorful whiskers.

Made in Villevere, which unites Villevere inventors, will bring exciting small machines and two great open workshops to the festival. In the Perfoconstructor workshop, we will learn how to use personal protective equipment , various hand tools , and how to construct according to drawings.

A workshop that reveals the secrets and working principles of internal combustion engines allows you to learn about the basic components of engines and various tools, and develop technical thinking and manual dexterity.

On the opening day of the festival, Kettybot and Bellabot from Roborend will greet guests and share surprises.

Kettybot also assists inventors in the PROTO cinema building workshop.

The Institute of Educational Sciences of Tallinn University offers the opportunity to get acquainted with various fun and educational robots at the Great Inventors Festival.

Student Satellite, which develops and sends its own satellites into orbit, offers the festival an opportunity to get acquainted with both the ESTCube-2 and SUTS models, and they also come with an exciting computer game where players can test themselves in navigating the satellite.

Hiigelmullid.ee puts PROTO’s factory premises to the test with noisy bubble balls .

We test giant bubble domes, put entire families inside bubbles, bake magical steam bubbles, and make bubbles explode in small fireballs.

Most importantly, children can have fun with soap bubbles themselves.

Students of Tallinn University of Technology invite you to a Leonardo da Vinci bridge building workshop at the festival.

We are building a bridge without fasteners, held together only by friction and gravity.

We will test how adding a load actually increases the strength of the bridge and develop the creative thinking that is typical of engineers.

At the festival, Tallinn International Kindergarten will introduce innovative methods for using music to develop the speech and cognitive skills of preschool children and will bring Musicon to PROTO – a unique musical instrument specially created for children.

In the Digipurgi and Robomik robotics and electronics workshops, you can discover step by step how electrical circuits work and what exciting things can be built. In the workshop, you can make a robot draw pictures and patterns and test how it can create music.

The world of electronics and robotics is worth discovering – here inventors can try, experiment, and experience how an idea turns into a working solution.

PROTO Science Theater of Inventors

PROTO Inventors Science Theatre offers a fast-paced and engaging experimental romp that shakes and surprises. In a humorous and playful production, we revel on the border between science and invention. Laughter, wonder and empathy are guaranteed.

PROTO Inventors’ Lab workshops

PROTO Inventors’ Lab will be transformed into a free invention area for the duration of the festival, where you can build a prototype of your own invention. On both festival days at 1 pm and 3 pm, you can create your own miniature cinema in the Inventors’ Lab – a moving invention that combines engineering, art and imagination.
