Fill your empty water bottles ⅔ of the way full with water.

Add in your glitter, Halloween confetti, Halloween creatures, bugs and googly eyes.

Add in 3-4 drops of food colouring and then put the cap back on the bottle and shake to mix.

To create orange, use two drops of red and two drops of orange food colouring.

Open the bottle and fill the remainder with vegetable or baby oil.

Leave a small amount of space at the very top so that the contents of your bottles can mix more easily.

Use a hot glue gun to seal the top of the cap, so that there are not accidental leaks with play.

Now they bottles are ready for the little ones to play.
