Lesson 9: Weights
Putting weights on the testicles sounds scary but it is not really dangerous. Just remember to obey the 60lbs limit. I am going to tell you how to do this method. You place the testicles on the table and put a rubber band around the testicles. A rubber band is essential because the testicles will just slide out from under the weight if they are not held down.
Applying the weight is the difficult part. Place a large flat surface over the testicles and you can place heavy objects on top from there. A big dictionary or encyclopedia works great. So long as you mind the 60lbs limit rule there is no risk of injury here.
