On weekends we invite you to take part in fun scientific experiments in Chemistry Laboratory (Curie Workshop) in the Energy and Technology Museum. The activity is dedicated to the whole family and anyone interested in chemical elements, their properties and the exciting science of materials.
- Liquid nitrogen – 196-degree cold nitrogen can freeze any substance that contains water – flower, fruit or berry. When nitrogen is added to boiling water, a thick cloud of nitrogen gas forms due to the temperature difference.
- Exothermic reaction of acids and bases – when household chemicals are mixed with foil, heat and hydrogen gas are released. We will watch how hydrogen gas, which is most commonly found throughout the Universe, inflate into a balloon and rise into the air due to the heat.
- Elephant toothpaste – why the concentration of substances is important and how, miscounted, instead of soap for humans a toothpaste for elephants can be made
- Non-Newtonian fluid – both solid and liquid: how to make a non-Newtonian fluid easily at home?
- The magic of color – when mixed with what vitamin does iodine turn it… colourless? And what to do to get the dark color back? Color magic!
Experiments are carried out on an optional basis and are constantly updated, so their program may vary. Experiments take place on weekends:
On the basement floor of the ETM, in the Curie Workshop named after the famous scientist Marie Curie. Laboratory visitors will be provided with protective gowns and/or goggles. Meeting place is the ETM information center. Participation of children (up to 12 years old) – with adult supervision.
Duration of the experiments – 40 min.
Price – visitor ticket + 2 Eur.
