EFFECTIVE FOCUSES AND THEIR CLUES Everyone was fed. Focus Secret Directory / Spectacular tricks and their clues Focus Description: The display will require three glasses, red cabbage, baking soda, white vinegar, a bowl of hot water, and a sieve. In the first glass, put a teaspoon of soda and top up with water. When the baking soda dissolves, the liquid will become clear. Cut up some red cabbage. Soak it in hot water. The liquid will turn purple. Pour it through a sieve into a second glass. Fill a third glass with vinegar. It looks colorless. After finishing the secret preparations, proceed to the demonstration. Don't show the glasses at first. Just start talking: - Once the Roman emperor Julius Caesar invited his friends Brutus and Antony to a cup of tea. "Let's drink something," suggested Caesar. "Here's some water for you, Brutus." Take out the first glass and put it on the left. "Here's some water for you, Anthony." Take out the third glass and put it on the right. "Here's some blackcurrant juice for me." Take out the second glass with purple liquid and put it in the middle. Brutus said, "Oh! Why do you have juice, and we must drink plain water?" And Caesar answered: "You will receive it." Pour some purple liquid into a glass - the water will turn blue. Antony said, "I don't want water either! I'd like strawberry juice." Caesar replied: "You will have it." Pour some purple liquid into the third glass - the water will turn red. "Perhaps I'd like more strawberry juice, too," Brutus said. Caesar replied: "Easily!" Pour some red liquid from the third glass into the first - the glass will also have red "juice". "It seems to me," Caesar said, "that I, too, would prefer strawberry juice." Pour some of the red liquid from the third glass into the second - now all the glasses are filled with red. Focus secret: Red cabbage juice turns red when reacting with acid and blue when reacting with alkali. When you pour the strong acid from the third glass into the weak alkali of the first glass, the acid clogs the alkali and the solution becomes more acidic and red. The same happens with the strong acid and the indicator in the third glass.
