Is it water going down a plug hole ?

JimBob an Upton are correct; it is a vortex of water:-

This one is in a 2litre plastic bottle, (a lot safer than chasing a waterspout :)).

Science demonstrators (Daveshorts et al) may wish to know that plastic "joiners" to create
 this "tame tornado" are available from this source:-
http://www.mutr.co.uk/prodDetail.aspx?prodID=949

There is a description of how to produce a "tame tornado" at the site (item 6):-

Is it the Reduced Shakespeare Company performing the complete works in London's West End on a Saturday night and there's a heckler in the audience, Row L, seat 17 ?...oh...and it's raining too and someone has let the tyres down of the hecklers car ?...

yes...yes I think that must be it...except..well...perhaps it's row M instead of L ?

Radula of a snail ?

" Definition of radula:-
 The ribbon of teeth possessed by most gastropods (and most other molluscan Classes). The Muricidae have a ribbon of numerous lateral rows of teeth. Each row has a central tooth flanked on either side by a lateral tooth. Teeth may bear smaller teeth called cusps. The shape and disposition of the teeth are of taxonomic importance."

CA-CHING! (slot machine pays off) ROBERT gets the jackpot.

Congrats! (No consolation prizes will be given - sorry.)

Michael, limpets as well as slugs (BUT NOT SEA SLUGS) have readula. The radula is often mistaken for a tooth and does function as a tooth for many species. It is actually a tounge with a builtin rasp. Besides snails, both the ones found on land and those in the sea, radula are also found in limpets, abalones and snails. They are not found in sea slugs, which are (were?) Nubibrancs. (DNA is making my taxonomy obsolete.)

Pictured is one of the many varieties of a radula.



(Left) Radula of the deep sea limpet, Neomphalus fretterae, Family Lepetidae
     
(Right) Radula of the slit shell mollusc, Scissurella crispata, Family Scissurellidae
Scanning electron micrographs; reprinted courtesy of  Dr. Carole S. Hickman,
Museum of Paleontology, University of California, Berkeley CA.                


The deep sea limpet's tongue, or radula (above, left) is used to scrape algae off rocky surfaces, and it is strong enough to bore a deep-set scar into the rock to which the limpet attaches (see the superfamily, Patellacea). The recurved tooth is hardened with iron and silicon oxides at its tip, in effect a sharp rasping tool. By comparison (above, right), the feathery structure of the slit shell mollusc's radula lacks hardened teeth. It is more suited to sweeping and filtering fine organic debris from the soft sands along the bottom, where this mollusc normally lives --a   mode of living like that of the other slit shell molluscs (see, for example, the Pleurotomariidae family).

Carnivorous Radula



(Right) The array of horny teeth shown belong to the radula of the Oyster Drill, Urosalpinx, a member of the Murex family noted for boring drill holes into heavy shells of mussels and other molluscs. The left and right ranks of teeth are hooked, and the middle tooth shows three cusps. Like all gastropods, the radular teeth are continually renewed from top to bottom, as they are worn away. In the case of Urosalpinx,  rather than depending on silicon- or iron-hardened radular cusps, drilling is facilitated by secretions of an accessory salivary gland used to soften shell materials.

OK this is not purely scientific, but there are some interesting physics involved.

is it a golf ball that was hit so hard, that the friction with the air heated it enough to change shape, and the spinning made it turn into an american football shape?

E=MC2... m=deg/360 X C... C= PiD

therefore E=deg/360 X 2(PiD)

Does pressure or ' lack of pressure ' have anything to do with it ?

Naw, it is the Lancastrian Rugby ball. Instead of armour and armies, this is going to be finnaly settled on the rugby field!
