One method to enhance the power of the lab sonicator

Besides of getting a more powerful sonicator, there is a simple method you can try to get more power out of the old sonicator.
the method is described in a journal paper by a Japanese researcher.
The method is simple: just add detergent to the water bath.
The result is substantial.
the reason is ovbious that the polymer has big molecular weight than water so the long-distance energy-transfer-ability is better.

Don't believe ? try it! and post the result here.
