Galaxy Jar – Science and Art mixed together.
For the last few weeks the boys have both been hounding me to let them make a lava lamp for their room. After some research into the topic, we discovered Galaxy Jars and the boys decided that these looked better and more fun to do. So we eventually found some time to make them after school. To be honest I was a bit skeptical to if these would turn out ok, I was not convinced that the colours would not mixed and that all we would end up with was a coffee jar full of black cotton wool! I was pleasantly surprise it turned out to be a really quick, simple, affordable, fun activity with little mess and they did look pretty cool. The boys really enjoyed and were in their element as we talked science to as we were doing it. Watching the colour blobs of water and glitter rise and fall though the oil.
Cost: Not much, as most can be found in your house.
Prep time: 10 minutes.
Prep time: 10 minutes.
Mess: Surprised as it was not that much, I expected more – but be prepared as it could potentially be more.
Boys rating: 10/10 this was a popular one.
You will need
- Clear container, bottle or Jar (any type as long as it has a lid – we used an old coffee jar)
- 3 x Food colourings (A few drops).
- Stick to mix.
- Oil (we used vegetable cooking oil but you could use baby oil if you prefer).
- 3 x small cups (we used plastic disposable ones- as it just made cleaning up on this occasion due to limited time).
- First add water to one of your cups (Amount depends on your jar side – you are aiming to fill one third of the jar).
- Add one food colour to one of your cups along with some Glitter and a table spoon of oil. Mix with the stick. Watch the colour blobs of water and glitter rise and fall though the oil.
- Then add to your jar.
- Place some cotton wool into the jar, used the stick to make sure the water is absorbed by the cotton. Make sure there is no water left.
- Repeat the steps 1-4 with your next chosen colour.
- Again, repeat steps 1-4 for your last chosen colour.
- Finally place on the lid and give a shake (We chose to superglue our lids on).
- We chose to use up the left over colours, glitter and oil leftover in the cups by pouring them in a spare jar together without the cotton wool. Just to experiment.
