btw I forgot
pretty useful references there and generally tons of useful information, so have fun with your cookie.
and @ Zizka:
seems like you directly referenced from the box.
THe huge wave just happens there because water doesn't change it's mass. In a faster pool thhere is no "interference" through the walls and the second wave is really soft.
Your timing could be also more on spot, try to observe the timing of the references more carefully.

and just because I am working on raindrops right now and wanted to add additional information
note that there is no jet for raindrops - pretty good ref-video:
