Ice Tunnels: Bring on the Summer Fun! Colorations® Liquid
Watercolor in an unforgettable art and science experiment that
costs only pennies. Try this on sunny day with lots of bright
sunlight and you'll experience amazing color, light refraction
and salt crystallization with the ultimate "hands-on" experience
for children of all ages. To make "Ice Tunnels," fill up a
variety of plain plastic containers with water and freeze

interesting mineral with many unique properties. It lowers the
freezing temperature of water, so it corrodes little crevices
into the ice as it melts down portions of it.
