CurioSitics Of Ice

In 1850, Mr. Faraday discovered that
two pieces Of ice placed in contact froze
together almost instantly Mr.. Tyndall
says: Gone hot summer day ! entered a
shop on The Strand in the window frag
monts Of ice we're lying in a basin. The
ltradc-man gave me permission to take
the pieces in my own hand; holding the
first piece | attached ali the other pieces
in the basin to it. The thermometer
was sixty degrees, and yet all the pieces
were frozen together In this way Mr..
Tyndall formed chain of ice. This ex-
pertinent may be made even in hot water.
Throw two pieces of ice in a pail almost
full of boiling water, keep them in con-
tact aud they win freeze together in des-
pite of the high temperature, Mr.. Fara-
| day made another experiment of the
same sort. lie threw into a vessel full
of water several small pieces of ice. They
tloated on the surface of the water. The
moment one piece touched another there
was an instantaneous rcfreezing, AT
traction soon brought all the pieces in
contact 80 that in IN instant an ice chain
was formed ....,. ........ .. ..

The phenomenon of refreezing is easily
explained. At the surface of piece OF
ice the atoms, which are no longer il
equilibrium on the outside, tend to leave
their neighbors, as it happens in boiling
or evaporation. Melting ensues. But
if two pieces of ice are brought together
the atoms on the surface are restored to
their equilibrium, the attractive attention
becomes what it was, the atoms resume
their relations with their neighbors and
juxtaposition ensues. In consequence OF
this property ice is endowed with singu
lar Elasticity. A rope and knot ol
