1.First you put the straw in the bottle.

2.Then you surround the bottle mouth with blue tac.

How to make ice cream

What you need:

• Sugar
• jugs
• sea salt

What we do

firstly Put the crushed ice and 200 gm of sea salt  in the big snap lock bag.

PUT MILK/ICE CREAM VANILLA ESSENCE ,SUGAR AND FOOD COLOURING INTO THE SMALL SNAP-LOCK BAG.

AFTER,  you put the small BAG IN THE BIG SNAP-LOCK BAG THEN YOU GENTLY SHAKE AND MOVE IT AROUND THE ICE UNTIL THE MIXTURE FREEZES.  YOU THEN DRAIN THE WATER OUT OF THE SNAP-LOCK BAG AND PUT THE ICE CREAM  IN A FREEZER  AND LEAVE IT IN THERE  FOR 2 HOURS.

Conclusion

The sea salt prevents the ice from  melting and the liquid in the small snap-lock bag turns the  cream into solid -  and that is ice    cream!
