- before some sport event (NBA finals 7th match) we write a question 'who will win, A (1st team name) or B (2nd team name)?'
- do 2 experiments with photon and slits:
* (A)
* (B)
- do not measure their results until tomorrow
- tomorrow (after the match is over) you measure result of the experiment of the team that won and destroy results of the another experiment
- (returning to the previous day): look which experiment shows inteference and which doesn't
