You have to test a pill for its effectiveness. You have 100 pills and 100 sugar cubes looking like pills. How would you design an experiment for this test?

Spoiler for my answer

Agreed. Even if the point is that we don't know which pills are sugar and which pills are real, the double-blind test with 200 people will still prove the effectiveness by the number of participants who show the desired effects of the real pill.
