Question about jet propulsion...
So over the weekend, we were floating around drunk in my swimming pool arguing over stupid stuff. Well, we starting talking about physics and it got ugly - even had my donut raft flipped over in rage!
Let me paint the picture for you...
You are sitting on a raft in the center of the pool - completely out of the water. You are holding a foam water blaster:
You suck water in from your right side and shoot the water back into the pool on the same right side.
Will it move your raft in the opposite direction (to the left)?
Would it change the outcome if you:
A) fired with the tip of the blaster IN or OUT of the water?
B) fired with the tip of the blaster OUT of the water but hit the pool side with the stream of water?
C) sucked water in from the left side and shot it out on the right side?
