Funnel in the context of Condensation funnel

A funnel cloud is a funnel-shaped cloud of condensed water droplets, associated with a rotating column of wind and extending from the base of a cloud (usually a cumulonimbus or towering cumulus cloud) but not reaching the ground or a water surface. A funnel cloud is usually visible as a cone-shaped or needle like protuberance from the main cloud base. Funnel clouds form most frequently in association with supercell thunderstorms, and are often, but not always, a visual precursor to tornadoes. Funnel clouds are visual phenomena, but these are not the vortex of wind itself.

A jerrycan or jerrican (also styled jerry can or jerri can) is a fuel container made from pressed steel (and more recently, high density polyethylene). It was designed in Germany in the 1930s for military use to hold 20 litres (4.4 imp gal; 5.3 US gal) of fuel or water, and saw widespread use by both Germany and the Allies during the Second World War.

The development of the jerrycan was a significant improvement on earlier designs, which required tools and funnels to use, and it contained many innovative features for convenience of use and robustness. Today similar designs are used worldwide for fuel and water containers, in both military and civilian contexts.

Water cure is a form of torture in which the victim is forced to drink large quantities of water in a short time, resulting in gastric distension, water intoxication, and possibly death.

Often the victim has the mouth forced or wedged open, the nose closed with pincers and a funnel or strip of cloth forced down the throat. The victim has to drink all the water (or other liquids) poured into the funnel to avoid drowning. The stomach fills until near bursting, swelling up in the process and is sometimes beaten until the victim vomits and the torture begins again.
