Summary

[edit]
Description
English: In this experiment, I show you how you can make thermal cards based on cholesteric liquid crystals. Cholesterol derivates can become a liquid only by slight heating, but when they change their aggregation state, they form so-called cholesteric liquid crystals which can interact with visible light and making such a colourful effect.

Eesti: Selles katses näitan kolesterooli vedelkristallidel põhinevate termokaartide valmistamist. Kolesterooli derivaadid muutuvad vedelikuks vaid vähesel kuumutamisel, kuid agregaatoleku muutmisel moodustavad nad nn kolesteerilisi vedelkristalle, mis võivad interakteeruda nähtava valgusega tekitades nii värvilise efekti.
Українська: Виготовлення теплових карт на основі рідких холестеричних кристалів. Похідні холестерину можуть стати рідиною лише при незначному нагріванні, але коли вони змінюють свій агрегатний стан, вони утворюють так звані холестеричні рідкі кристали, які можуть взаємодіяти з видимим світлом і створювати такий барвистий ефект.
