MAGIC ICE

TOWER

You might know that water turns to ice at

32°F (0°C), but did you know that it can stay

liquid below this temperature? Here’s how

to supercool water with magic results.

YOU WILL NEED

Unopened bottle

of spring water

Bottle of tap water

A freezer

Ice cube

Put one unopened

bottle of spring water

and one tester bottle of

tap water in the freezer.

After two hours, check

every fifteen minutes

until the tap water is

frozen. Remove this

from the freezer, or

it may explode!

Keep an eye

on the clock!

Remove the unopened

spring water from

the freezer. It should

still be liquid, but

supercooled below

zero. Take care not to

knock the bottle—

it might instantly

freeze! Open it and

slowly pour the water

over an ice cube.
