The TMW offers a diverse program for upcyclers and hobbyists, sets concrete canoes afloat, makes aluminum cans glow, shreds smartphones, and invites visitors to take a first look at sustainable innovations. On October 4, 2025, visitors can explore a wide range of activities together with the whole family and experience the new exhibitions Material Worlds and More than Recycling.
Teenagers & Adults
Special Day

ALUMINIUM UPCYCLING

6 pm–midnight | Level 2 | Station activities

Things get hot when experts from Montanuniversität Leoben demonstrate how aluminum cans are melted down and cast into coin blanks. Afterwards, you can get hands-on and mint your own coin from them.

SMARTPHONE IN THE CYCLE

6 pm–midnight | Level 2 | Station activities

Have you ever wondered what’s inside your smartphone and what happens to it once it’s no longer in use? Experts from Montanuniversität Leoben will explain the material cycle of a smartphone at four interactive stations – from raw material needs and production to recycling. You’ll be amazed to see how shredded phone parts are transformed back into valuable resources for new products.

CONCRETE CANOE: FLOATING INNOVATION

6 pm–midnight | Level 2 | Station activities

Dive into the fascinating world of concrete! Together with Beton Dialog Österreich, the University of Applied Sciences Campus Wien presents its 4.5-meter-long concrete canoe. Made from recycled concrete, this canoe was developed for the Concrete Regatta, where not only athletic ambition but also sustainable material use and creative construction methods take center stage.

AUSTRIAN GREEN PITCHES

7 pm / 8 pm / 9 pm / 10 pm
Approx. 30 minutes | Level 2 | Stage program

In cooperation with the Austria Wirtschaftsservice Gesellschaft mbH (aws), the TMW presents six young, sustainable innovations from Austria in the Innovation Corner. In five-minute pitches, meet the creative minds behind the projects: All But Sugar, Hempstatic, LOCI®, MATR® and REEDuce.

SPOTLIGHT TOUR MATERIAL WORLDS

6:30 pm / 8:30 pm / 10:30 pm
Approx. 15 minutes | Level 2 | Meeting point at the exhibition

Whether rubber, steel, concrete, precious metals, or even air – the range of materials used is enormous. Some raw materials are obvious, while others are cleverly concealed. In this tour, we take a closer look: How can we extract these valuable resources in an environmentally friendly way and keep them in circulation for as long as possible?

SPOTLIGHT TOUR MORE THAN RECYCLING

7:30 pm / 9:30 pm / 11:30 pm
Approx. 15 minutes | Level 2 | Meeting point at the exhibition

Circular economy is more than just recycling! It’s linked to questions such as: When do things lose their value? How do we treat valuable resources? What needs lie behind our consumption behavior? In this tour, we question our daily decisions in areas such as food, housing, electronics, fashion, and lifestyle.

HIGH-VOLTAGE SHOW

7 pm / 8 pm / 9 pm / 10 pm / 11 pm
Approx. 15 minutes | Level 2 | High-voltage room

This impressive show takes you into the world of charges and currents! We generate electricity with extremely high voltage and conduct amazing experiments: lamps light up without cables, and meter-long bolts of lightning flash freely through our safety cage.

Tickets are available free of charge at the museum ticket desk starting 2 hours before the show.

MAKER*SPACE TECHLAB

6 pm–10 pm | Level 3

Ready to bring your ideas to life? In the techLAB, with the support of our Explainers, you can create stylish wallets from upcycled materials or vegan leather.

MINIXPLORE

6 pm–10 pm | Level 3

The interactive exhibition for families with children aged 3–8 inspires experimentation and movement. In this diverse and artistic play landscape, countless stations await curious young explorers!

The children’s area is open continuously. No slot reservations required.

MINTI

6 pm–10 pm | Level 3

The discovery area for families with children aged 1.5–5 offers young explorers plenty of space for movement and playful experiences, encouraging the curiosity of the youngest visitors.

The children’s area is open continuously. No slot reservations required.

VR FLIGHT WITH BIRDLY®

6:30 pm–11:30 pm | Level 1

With Birdly®, you can fly like a bird thanks to a realistic virtual reality experience and discover fantastic perspectives. For an even more vivid full-body experience, you control the flight by moving your arms and even feel the wind in your face.

Tickets for the VR experience are available at the ticket desk (€ 3.90).
