How to accelerate the speed of fruit decay?

There are many ways, the so-called decay is that the things inside are broken! You can blanch in hot water for about 5 minutes, and blanch for a longer time is better. Fruit won't change color too much. Now take it out and put it in a very damp place, such as (toilet, kitchen), because there are more molds and bacteria there, so it is easier to accelerate the decay of fruits, and it will rot in less than 3 days.
