** one makes ears longer
** another makes teeth longer
** another makes whiskers curly
** another turns the nose white

Betaro put each magic potion into a separate beaker. He put pure water into another beaker, so there are six beakers in total. The beakers are labeled A to F. The problem is, he forgot to record which beaker contains which magic potion! To find out which potion is in each beaker, Betaro set up the following experiments:
Experiment 1: A beaver drinks from beakers A, B and C together – the effects are shown in Figure 1.
Experiment 2: A beaver drinks from beakers A, D and E together – the effects are shown in Figure 2.
Experiment 3: A beaver drinks from beakers C, D and F together – the effects are shown in Figure 3.
