Use a test dummy to determine the pain of the impact. The lesser the impact the better. Just make sure that the dummy can pass through a lot of obstacles.

Enter the science lab and perform a series of tests. The goal of your test is to hit the dummy to the goal object. You do need to keep an eye of the dummy's pain meter.

Test the pain level of your dummy. It should pass the experiment by hitting the target object without going through a lot of pain. So go ahead and begin the experiment.
