Hello everyone, I need some idea brainstorming. I am doing an experiment where I drop objects in to water (in a lake) and measure the impact forces. Now, the thing is the objects need to be dropped from as high as 30 meters up in the air and other lower heights as well. Can anyone think of a good idea to take the objects to that height? I tried using a drone, but it didn't work very well at that location. Any ideas would be greatly appreciated. Thanks.
