Snapshots of water-filled balloons bursting figure as amazingly frozen moments in time. Granted, they also bring back memories of when you were a young scamp, mischievously dropping water bombs on hapless cyclists from overpasses,
or soaking whole streets in drive-by drench-athons – but those days of innocence are gone now. So, it just leaves us to sit back and wonder at the beautiful physics of the things – as well as the devilish uses to which they can be put.
In a general sense it’s all to do with pressure – like peer pressure, but without the wicked little peers saying stuff like, “go on, soak the suckers, or we’ll soak you”. Yes, pressure. The pressure of the point of the pin, needle or whatever else it is that exerts force on the balloon, and the high pressure of the water inside the balloon, which is suddenly allowed to disperse. Since the water cannot all escape from the tiny hole pricked in the elastic material, it bursts to even out the pressure.
But enough talk; let’s see some shots of a water bomb bursting in sequence. A dart is let fly en route to puncture a balloon…
When the dart pierces the skin of its target, the balloon creases as it starts to split open, while ripples in the water’s surface tension begin to appear.
The water’s effervescence becomes more turbulent as it bulges, making its escape, even as the latex of the balloon surrenders to gravity.
Then there’s the magic moment from a photographic point of view, the instant when the water, shorn of its rubbery mould, still holds its roughly pear-shaped form…
…Before collapsing in a shower of water droplets.
s with so many things that are meant to be fun, some folks seem to take it all so very seriously. Throwing techniques include: not tying the water balloon closed but instead just twisting the end a few times so water begins to squirt out on the flight path; and overfilling the balloon so there’s enough weight and water to cause a good soaking even if it explodes on the ground. There are even accessories called ‘water balloon launchers’ as well as different types of nozzles and valves, all brought to you by a variety of money spinning manufacturers.
Maybe we’re traditionalists here at EG, but give us any balloons and we’re away, off on a journey of mischief and mayhem. Yes, we know you’re not supposed to use standard air balloons because they’re meant to be too thick, but when you’re holding a water bomb as big as a watermelon, no matter how hard to handle it may be, you know you’re going to cause a splash if it’s dropped from a great height. Oh yes.
