Engineers Build Coolest Water Gun Ever by Nobody: 7:29pm On Jul 08, 2014
Finally, we have an engineer who’s
putting his degree to proper use! 27-
year-old Londoner Alex Bygrave has
used all his technical know-how to
come up with the ultimate invention –
an awesome Gatling water gun. Believed to be the world’s most
sophisticated Gatling-style weapon of
its kind, the gun features a 10-liter
water tank, six barrels and a 40-foot
firing range. Alex spent 50 hours designing and
building the pistol from scratch,
making use of 55 separate parts made
of everyday objects. “I had to first
break down the mechanics of how
the Gatling gun worked, and then build it up using a mix of all sorts of
components,” he said. “For example, I used a black cab’s
windscreen wiper to provide the
rotary motion of the pistol and laser
cut mechanics to create an intermittent
barrel rotation.” According to Alex the
windscreen wiper motor was ideal for the project because it has a very high
gearing and is easy to pick up cheaply
second hand. “Standard plumbing pipes and fittings
were used wherever possible, so that
as much of the pistol could be made
from stuff in your local DIY store.” Alex used a self-setting rubber called
Sugru with the existing parts to make
custom valves, pistons and injectors
that are integral to the Gatling motion
and to the coloring of the water jets.
He also used a carbon dioxide welding canister to pressure two large
fire extinguishers, so the water can
fire out long distances. A small
amount of food dye in the barrels
ensures that the water shoots out in a
riot of colors. The construction of the pistol was
sponsored by Sugru. Their website
declares: “We love testing the limits of
what Sugru can do. Which got us
thinking. With all of this Sugru, and
these amazing people, could we create the world’s coolest water
pistol?” Their video shows the co-founder of
the company asking mischievously:
“Water pistols are awesome. But what
if they were even more awesome-
erer?” Alex and a colleague then
proceed to build the pistol and fire colored water all over their
colleagues. According to Sugru
production assistant Jon Radclyfe,
“the pistol weighs an absolute tonne
but works like a dream.”
