We did this activity back in January but I never got round to blogging it and this week being such an important one where I attended the Matilda Mae Remembers Service, and we marked the one year anniversary of her funeral it seems like a nice time to do it.
This whole thing was Gabs’ idea. Producing tens of thousands of 2D pictures of planets was no longer satisfying him and he really, really wanted to make a 3D version somehow. Now I am incredibly lazy and tend not to plan ahead so we didn’t really do this quite as perfectly as we might have, with little balloons inside to make them perfectly rounded, but it was still a major undertaking (it took us two days!) and Gabs was really able to do everything himself so it was a good option for us. I’m sure we will improve on it and make another Solar System as we hone our technique!
Day 1: Inner Solar System
So basically, we picked up a mountain of Metro newspapers from the tube station and ripped them into roughly two-inch wide strips (Gabs wasn’t interested in this bit, or coordinated enough, so I did it and piled them in a bowl for him to take) and then mixed flour and water in a bowl to make a sticky paste. I followed some online recipe, I can’t remember the quantities and anyway I found it too runny and added a lot more flour so it’s irrelevant… 🙂
We started with the Sun, and scrunched up a load of newspaper in a ball (which is why our spheres didn’t come out too round! But it was easier for Gabs and he loved it) and then started laying the paste-soaked strips across it in layers.
Once we’d added some smaller inner planets, we put them in the oven on a low heat to speed up the drying process (we don’t have an airing cupboard and were impatient to start painting!) I should point out at this point that even though we used non-toxic paints it still makes the oven stink so you need to allow time to clean and burn off the smell before cooking in it after.

Then once the Sun was fully dried Gabs mixed the right paint colour (a mix of gold, yellow, orange and red paints) – something he took fastidious pride in! It took several coats of thick paint and we had to partially dry each one and then paint the bottom and put it back in the oven upside down to cover the whole of the sphere. It worked better with some of them to roll the whole planet around inside the bowl of paint to get it really well covered.
Gabs painted green land-masses onto the already dry blue oceans of Earth and once they were all dried we called it a night as we were exhausted! This worked out pretty well because Gabs was delighted by the results of his Sun and Inner Planets and it gave him something to look forward to the next day.
Day 2: Outer Solar System
The next day was more challenging because we had the planets with rings to deal with and more complex colours. We started the same way as before with the newspaper balls and paste. Our scale wasn’t very accurate, that’s something we’d like to improve on next time but it would have meant having an absolutely enormous Sun or teeny tiny inner planets to leave ourselves room for the right comparitive sizes of the bigger planets so we just approximated as best we could this time.
We had a lot more paint mixing to do for the more unusual shades of the gas giants and lots of layering to do for the cloud formations on Jupiter. First we painted it brown, then dried it and painted the rings of circling orange clouds, dried that.. then a splodge of red for the Great Red Spot and silver (we didn’t have white) on the top and bottom for the polar clouds.
We made the rings by cutting them out of purple cardboard and colouring with felt-tip pens. Saturn’s are much wider than Uranus’ and go round the middle rather than top to bottom which was much easier to fix on but somehow we made them just the right size to stick around the middle.
Drawing Saturn’s rings
Did you know there is a storm on the North Pole of Saturn which is naturally shaped like a perfect hexagon?! Gabi told me this and I didn’t believe him at first until I checked it out myself but it’s true. One of the great wonders of the Universe!
Gabs tried very hard to paint it on but it went a bit splodgy. Another thing to aim for in our next one. So here they are, our finished planets, the whole Solar System including a little moon to go around Earth. The big gap Gabs left between Mars and Jupiter is for the asteroid belt… I have no idea how we’re going to make that!
The funniet shaped planets we have ever seen!
Creating the orbits round the Sun
As you can see our round paper-maché dried a lot less round and then the paint coagulated in clumps making some of them reeeally bumpy. Let’s be honest they are the funniest looking planets you’ve ever seen, right?! But Gabs LOVED them… he felt so proud because he considers that he made them almost all by himself, and they have been played and played with for weeks… They are great for playing at making the planets orbit around the Sun and the moon orbiting the Earth and they’re so hard and durable they are hard to break, although we keep losing the little ones around the house.
This was a great project for us, we had great fun and Gabs was in absolute heaven. He really felt special that Mummy had gone to all the trouble of this two day project to make him happy, making me feel like the best Mummy in the World. 🙂 It’s messy and time consuming but also pretty easy… I highly recommend it! If you have any tips on making an even more accurate one, maybe with balloons and any ideas for the asteroid belt, please write below! And look out for our next 3D Universe project…
