Sneaking a can of soup into a museum is also just... really cheap? How much did this cost to pull off? 2 people, 2 museum tickets (if that particular museum required an admittance fee at all), and a can of soup. Museum tickets aren't THAT expensive, nor is soup. This could be pulled off by anyone in a matter of hours with no real preparation, training, or major financing and now they're on the covers of god knows how many media publications. Considering how much attention they're getting vs. how much they put into pulling this off, the cost-benefit ratio is incredible
