Underwater ‘Fireworks’

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.DSCF9188

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)
  • water
  • 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
  • teaspoon



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.

DSCF9158Give it a good stir!

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!

DSCF9186 DSCF9172 DSCF9177We 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!

Oh S wanted me to stir the water too and it created a whilrpool, which was fun to watch and another learning moment! DSCF9163 A quick and easy indoor activity. x


Mini Volcanoes

More science fun with kids. Yay!


Two of my fave things to keep S entertained have to be vinegar and baking soda (I always make sure I have some in my cupboards!) One of his favourite things – volcaones.

I saw this ‘experiment’ on, where else – pinterest, so had to give it a go and it was a hit. All you need is…

  • baking dish or tray with sides
  • vinegar + small bowl/cup for it to go in (any vinegar woill do but I used white)
  • baking soda (bicarbonate of soda)
  • pipette or medical dropper
  • food colouring (optional)

Pour a layer of baking soda in your chosen dish. It needs to be about a fingertip deep so first make sure you have enough of the white stuff (or behold the meltdown when you have to abandon the experiment before you have begun..) I mixed a little food colouring in 3 small dishes so we had 3 colours to work with. The experiment is still fun with just plain old vinegar though. Next hand over to your child the pipette (bought mine from a chemist) and watch the joy on thier face as they drop the vinegar onto the baking soda and wacth the ‘volcanoes’ erupt!


J was well into it too! This is great for fine motor skills, concentration, learning about reactions and colour mixing, but best, its pure magical fun for the kids.  Of course by the end it was one big colourful mess but hey, no harm in that and it was super easy to clean up. Image

Definately one will be doing time and time again! x

Science fun #2 underwater volcano!

Another great experiment to try if you have nosey little people in your house  – fun as it involves water (what kid doesn’t love water?!) and ya a sneaky learning experince at the same time…

really simple fun experiment my son saw in a science book we got from the library (yes he gets book out on scince, that is my four year old!)

Its basically a way to observe how hot and cold water mix together…


We filled a see through bucket with iced water and added red foood colouring, then a small bottle with hot water, coloured blue. You need to put a lid or small plate over the hot water and only remove it once it is in the cold water. I would suggest the grown up does this part, especiallyas it works best if the water is very hot.


Amazing swirly effect as the hot water mixes with the cold, making billowing underwater ‘clouds’IMG_2812Note how Senny has his face pressed right up against the bucket to see what s going on!

So many questions were raised, and adfter Sennen played with the mixed water noting how is had turned purple. Who said science was dull?!


My mini scientist – volcanoes

IMG_3451 IMG_3445 IMG_3446my son Sennen, loves science. He doesn’t realise that loves science yet, as he is only 4 – but he is fascinated by all things that react, erupt, change, evolve… Pretty much like all boys really! If there is something that is going to involve a messy reaction or interesting ‘magical’ change then he loves it, and of course wants to know “why?” at every step of the way. So I have become quite adept at finding ways to bring science into his life (and that of little J who’s two) mainly through Pinterest (what would I have done before Pinterest??!!!) but we also got a great book from the library recently which has some great kids experiments. High five to good old libraries!

One of our favourite things to do was to make volcanoes on the beach. It’s so simple to do, and yet soooo effective and most importantly FUN!!! what more could you want then colourful eruptions and sand combined?! All you need is:

  • White wine vinegar
  • Food colouring
  • Bicarbonate of soda (baking soda)
  • small plastic cup and spoon.
  • A beach or sandpit. Or you can do this in your garden with mud. (woah! mess alert!)

Before you set off, add your food colouring to the vinegar. We did orange, naturally, as S wanted the authentic lava look. But let your wee one choose! Green lava? why not!

Let your little mate sculpt a volcano. If your like me and totally need to get involved, sculpt your own one too. (That way it can be your own perfect volcano, yay!! and you will feel like a good parent for not taking over your child’s attempt… Oh yes it does happen to the best of us, oops)

Poke a little hole in the top and put your cup in, then spoon some baking soda into it. Now let Einstien pour in some vinegar and voila!!! Volcano eruption!!!! The great thing about doing it on a beach was the sea water made a moat around our volcanoes and the water turned bright orange, so even tho the eruption fun was over fairly quickly, we spent a good hour just playing with the water and volcanoes. Next time I am definitely taking toy dinosaurs too…
