Just starting	Magnetic interaction - they do not care about the Earth's North pole anymore	Magnetic order on the overhead projector	Closeup of the magnets	This "paper" is sensitive to the magnetic field. There is refrigerator magnet behind. Note the alternating strips of N and S poles.	After the paper is carefully removed, it remembers the magnetic field
Polarized light comes out of the LCD projector	Thermal response of the liquid crystals	The heath of the hand creates a ghostly image	We cooked a calculator - the black area is warm enough to make the molecules disordered	Pouring liquid nitrogen ...	... on a superconducting disk
Superconductivity kit	Perovskite model	The "phase transition machine"	Symmetry breaking transition happened	This is how the weights were suspended	The end of the "double pendulum" - see the notch that keeps the string in place
The best part: questions and answers	A little demo that did not fit to the talk: levitating a spinning magnet	Spinning magnet	Spinning magnet again
