		+	There are two complexities not covered by the current description. The first is the force will decrease at higher altitude since the water jet slows down with gravity, which is easy to model with basic physics. The second is the force depends on whether the water stops when hitting the umbrella or whether is bounces off and is redirected downwards. --[[Special:Contributions/2600:4040:99D4:8B00:14A1:D035:B0B4:2394\|2600:4040:99D4:8B00:14A1:D035:B0B4:2394]] 17:18, 10 October 2025 (UTC)
