What happens when you pour a liquid into a pool of the same liquid? As far as most people think and so did our group until we understood this fascinating phenomenon, both liquids will merge into one body immediately upon contact. The bouncing jet is a phenomenon that happens when a Newtonian liquid is streamed or poured in a pool of the same exact liquid under certain conditions. These conditions occur when the liquid is Newtonian, the pool is of the exact same liquid, and the pool of water is moving . When streamed into the pool, liquid will bounce off the surface of the pool while maintaining separation. This is instead of merging with the pool, if and only if the conditions are satisfied.
