An early explanation of the physics
of stone-skimming was provided by Lazzaro Spallanzani in the 18th century.
The stone generates lift in the same
manner as a flying disc, by pushing water down as it moves across the water at
an angle. Surface tension has very little to do with it. The stone's rotation
acts to stabilize it against the torque of lift being applied to the back.
Research undertaken by a team led by
French physicist, Lydéric Bocquet, has discovered that an angle of about 20°
between the stone and the water's surface is optimal. Bocquet and his
colleagues were surprised to discover that changes in speed and rotation did
not change this fact. Work by Hewitt, Balmforth and McElwaine has shown that if
the horizontal speed can be maintained skipping can continue indefinitely.Earlier research reported by Bocquet
calculated that the world record of 38 skims set by Coleman-McGhee,
unchallenged for many years, required a speed of 12 m/s (25 mph), with a
rotation of 14 revolutions per second.
Or you could take our advice and pick
up a stone, Chuck it, Hope for the best.

Las Ramblas Ramblers (Stone Skiming Division) Head to the Island of Kerrera for a Pre-skim Saunter to Gylen Castle, Ronald Binge missed the ferry so headed into Oban to drown his sorrows
Marion, Bruce, Linda, Neil,Sam, Alfie, Andy, Jill, Kevin, Kay, Haddie, Bob & Sally are joined by Chas &
Jaks.
Gylen Castle, on the southern part of the island of Kerrera
in Argyll and Bute, juts dramatically into the sky on the tip of a promontory
overlooking the Firth of Lorne.
Built in 1582 by the Clan MacDougall. Gylen was only occupied for a relatively short
period of time. The castle was besieged then burned by the Covenanters under
General Leslie in 1647 during the Wars of the Three Kingdoms.
In May 2006 a restoration of the castle was completed with a
£300,000 grant by Historic Scotland and £200,000 raised by worldwide members of
Clan MacDougall.

Las Ramblas head out to Loch Lomond for a Sunday Stroll,
surprisingly Neil arrived first at the meeting point unlike Martha Tilton who came up with the feeble excuse that she was helping Bruce in Cowdenbeath with a couple of big sums
Gillian, Alison, Marion, Neil, Alfie, June, Avril, Gary, Layla, Ryan & Wilf set out from Rowardennan for a saunter on the shores of
Scotland's loch that doesn't rely on a Monster to pull in the tourist.
Loch Lomond is a freshwater loch lying on the Highland
Boundary Fault, often considered the boundary between the lowlands of Central
Scotland and the Highlands. It is 39 kilometres (24 mi) long and between 1.21
kilometres (0.75 mi) and 8 kilometres (5.0 mi) wide. It has an average depth of
about 37 metres (121 ft), and a maximum depth of about 190 metres (620 ft). Its
surface area is 71 km2 (27 sq mi), and it has a volume of 2.6 km3 (0.62 cu mi).
Of all lochs and lakes in Great Britain, it is the largest by surface area, and
the second largest (after Loch Ness) by water volume. Within the United Kingdom,
it is surpassed only by Lough Neagh and Lower Lough Erne in Northern Ireland.
Traditionally a boundary between Stirlingshire and
Dunbaronshire, Loch Lomond is currently split between the council areas of
Stirling, Argyll and Bute, and West Dunbartonshire.
Loch Lomond is now part of Loch Lomond and the Trossachs
National Park. Ben Lomond is on the eastern shore: 3,195 ft in height and the
most southerly of the Scottish Munro peaks. A 2005 poll of Radio Times readers
voted Loch Lomond as the 6th greatest natural wonder in Britain.
The loch contains thirty or more other islands. depending on
the water level. Several of them are large by the standards of British bodies
of freshwater. Inchmurrin, for example, is the largest island in a body of
freshwater in the British Isles.
Several of the islands
appear to be crannogs, artificial islands built in prehistoric periods
One of the loch's islands, Inchconnachan, is home to a
colony of wallabies.

Las Ramblas head into Perthshire for a Bimble to the De'ils Cauldron in Comrie.
Carole King had hoped to join us but took fright at the amount of Seismic activity in the area, she sent this little ditty so we could whistle while we walk.
Gillian, Alison, June, Marion, Bruce, Neil, Linda, Sam, Alfie, Avril, Garry, Ryan & Wilf are joined in the Shaky Toun by Geraldine.
Before we set of let's check in with Sean for a quick Weather Report.
"Well Las Ramblas Light Showers in the morning giving way to a very pleasant day for a saunter "
Comrie sits at the confluence of three rivers. The River
Ruchill and The River Lednock are both
tributaries of the Earn , which itself eventually feeds into the Tay . The name
Comrie is of Gaelic origin and is derived from the Gaelic word conruith meaning
'a place where rivers meet' or 'confluence'. Due to its position astride the
Highland Boundary Fault it has historically experienced frequent earthquakes
and Comrie is now nicknamed the 'Shaky Toun. In the 1830s, around 7,300 tremors
were recorded and today Comrie remains one of the most geologically active
areas in the United Kingdom and records earthquakes more often, and to a higher
intensity, than anywhere else in the United Kingdom. Comrie became the site of
one of the world's first seismometers in 1840.
The village's position on the Highland Boundary Fault is
unique. To the north of the village, Ben Chonzie and the Grampian Mountains
rise majestically, while to the south of the village wide and open moorland is
joined by lesser mountains and glens which provide a unique range of terrain
and ecology.
There is significant evidence of prehistoric habitation of
the area, characterised by numerous standing stones and archeological remains,
which give some insight into the original Pictish and later Celtic societies.
In 79AD the Roman General Agricola chose what are now the
outskirts of Comrie as the site to build a fort and temporary marching camp,
because of the area's strategic position on the southern fringe of the
Highlands. The fort is one of the lines of so-called "Glen blocking"
forts which runs from Drumquhassle to Stracathro and includes the legionary
fortress of Inchtuthil.
A granite obelisk atop Dùn Mòr to the north commemorates Henry Dundas, 1st
Viscount Melville. This monument is reached via a woodland trail through wooded
Glen Lednock in which is to be found the
Slocha'n Donish or De'ils Caldron. The trail begins in the village, at Laggan
Park and ascends through a native forest of pines, oak, elm, ash rowan, alder
and beech to Glen Lednock. Via The Shaky Bridge (although the original shaky
bridge was replaced with a decidedly less shaky successor) the hiker is greeted
with a splendid view of Glen Lednock, a truly highland landscape where a single
lane road leads higher to Glen Lednock Reservoir and the Munro, Ben Chonzie.
From here Dùn Mòr and the Monument are easily reached, offering unparalleled
views across Strathearn and further west to the central highlands. A swift
descent (or ascent depending on route chosen) leads through a long, steep,
wooded gorge which contains the impressive Deil's Cauldron. Here the river has
cut a high, cascading waterfall in the surrounding rock, with pools below
resembling a boiling cauldron. It is said that a water-elf, Uris-chidh resides
here and attempts to lure victims into the treacherous waters. Following the
path down a lesser companion to the great falls, The Wee Cauldron which offers
a calmer view of the river. Following the path through the forest eventually
returns the walker to the village.
