The telecasting is of an gist known in fluid dynamics as the coalition shower , which can be observe ( provided you have admittance to a video tv camera with a sufficiently high frame rate ) when a drop of liquidness is deposited very gently onto the airfoil of a layer of the same liquid state . Fuck Yeah Fluid Dynamicsexplains :
When a droplet impact a pool at low speed , a layer of atmosphere trapped beneath the droplet can often preclude it from immediately coalescing into the puddle . As that air bed drains by , surface tension pulls some of the droplet ’s raft into the pool while a smaller droplet is exhaust . When it bounces off the surface of the piddle , the procedure is retell and the droplet grows small and smaller until surface tenseness is capable to completely absorb it into the pool .
Pretty awful , correct ? In the video shown up top , the effect manage to repeat itself four times ( in what scientist who hit the books liquid grease monkey call “ result ” ) before the viscous properties of the take a breather pool become too unattackable for the smallest drop to withstand coalesce whole .
And while the highest figure of events I ’ve been able to find anywhere else is five ( see the television above),MIT ’s John Bushclaims to have watch over as many as seven such event in a quarrel . I just like he ’d included a video of it …
