Not really fireworks at all. Just a simple experiment ulitising the properties of oil and water, and the beautiful result of food colouring unfurling and spreading wonderful patterns and colour in front of your astonished child (and your own) eyes.
Note – before you start, explain carefully to your child that there will be no real fireworks invloved, just an underwater display similar to firewrks. That way you won’t have a sulking toddler on your hands. Just saying…
You will need:
- Glass jar,vase or similar (Taller and slim is better that a bowl)
- 2 tablespoons oil – any veg oil will do
- Red, yellow, blue food colouring – no more them 3 drops of each colour
- small measuring jug
- measuring spoon
Fill you jar/vase 3/4 full with water
Pour your oil into a small, easy pour jug. Add 2-3 drops of each food colouring no more then this, LESS IS MORE! (*note, we first did this with 3 colours, the second time with just two. I actually preferred only 2 colours as they mixed to form a secondary colour i.e. yellow and blue made green, the 3 colours together ended up a brown shade which wasn’t so exciting. Too much food colouring won’t give you good ‘fireworks’) Let your child to stir the oil and food colouring into the jug to break the droplets apart, they won’t mix.
Tell small person to carefully, slowly (s.l.o.w.l.y….gahh we had one big mess when it all overflowed) pour the oil mixture into the water. Now wait…it takes a little bit of time…but sit back and watch with fascination as the oil and water separate, and ‘ta-daaaah!’ there you have it, underwater fireworks!
We repeated this a few times till they got bored, (which usually takes S about 5 minuts) It was really was interesting seeing the different colour combinations and wacthing the colours slowly unfurl in the water, just a little bit magical. I’m not sure if ‘fireworks’ is the best term for this underwater display, but it kind of adds to the drama so I’m going to stick with it!
