Care to see a
magic trick?
YOU WILL NEED
→ 2 test tubes
→ measuring spoon
→ litmus solution
→ tartaric acid
→ cup of water
HERE’S HOW
1. Before the audience enters, get a test
tube ready by adding 1 small spoonful of
tartaric acid to it. From several feet
away, your audience won’t be able to
tell that there’s anything in it.
2. While the audience is watching, make
some “blue ink.” Fill a second test tube
with 5 cm of water and add 5 drops of
litmus solution (do not let the audience
see the litmus bottle). Shake! Ready?
Now mumble your mysterious magic
spell: “Listen, ink, to my magic cry, turn
to red in the blink of an eye!”
3. As you do that, pour the “blue ink” into
the “empty” test tube and gently swirl
the test tube.
Safety Note:
For tartaric acid, note the “Information
about hazardous substances” on page 7!
