Apr 21, 2023 Experience «Blessed Bill» By odb-abai inNews, Без рубрики On April 21, a very simple and spectacular chemical experience «Blessed bill» was held as part of the Laboratory Laboratory Laboratory. For this experiment, we needed: water, alcohol, lighter, tongs and, of course, the bill itself. We used old Soviet rubles, which have long been not in monetary circulation. The essence of this experience is as follows. When we set fire to the bill, alcohol begins to burn. The temperature at which it burns is insufficient in order to evaporate the water with which the paper bill is impregnated. As a result, all alcohol burns out, the flame goes out, and a slightly wet bill remains intact. Everyone who wants to become a participant in various experiments of the library laboratory is invited to the library!
