Crunchable candy crystals

What you'll need

• Water bottle
• a saucepan
• granulated white sugar
• food colouring (optional)
• flavouring ( optional )
• a round edged wooden ice lolly stick
• a thick glass jar
• a clothes peg
• kitchen roll

 

step 1

ask a grown up to heat to cups of water 

in a spotlessly clean saucepan until 

it starts to simmer . Slowly add four

cups of granulated white sugar,

a little at a time, stirring as you go .

 

step 2

Stir the water until all the sugar has dissolved .

It may be necessary to turn up the heat .

Even a few undissolved grains will cause

the experiment to fail .

 

step 3

If you want to add food colouring put in

several drops. You can also add flavouring

for example a dash of fruit juice or a drop 

of vanilla extract if you like ask a grown up

to pour the liquid into the glass jar. Be careful

as it will be very hot.

 

step 4

moisten one half of the ice lolly stick with water

and then roll it in sugar. lower the coated half

of the stick into the jar , making sure it 

doesn't touch the bottom or sides .

Use a clothes peg to hold the stick 

in place.

 

step 5

Cover the top of the jar with a sheet of kitchen roll

to keep dust out, then place the jar in a cool , dry

place.

 

step 6

After a few days , crystals should start to form

on your stick. When they don't seem to be growing

any bigger, take the stick out and tuck in !
