Toy Review : Create a Geode

Toy Review : Create a Geode

Science toys are hugely popular at the moment. I am not particularly ‘sciency’ but my eight-year-old daughter loves experimenting and making concoctions! When she saw this Ultimate Science Kit come into stock, she knew she wanted one, so she asked her uncle to buy it for her birthday, which he willingly obliged.

To be honest, I didn’t really know what a Geode was, so I had to look it up and I discovered they are ‘hollow rocks with sparkly crystals inside’.

Toy Review Create a Geode Science Kit

This science kit isn’t expensive (it costs €12.99) and in my opinion, you get what you pay for when it comes to this kit. I found the instructions very hard to follow and I ended up having to check out some YouTube videos to get some idea of what exactly we were to do. This kit is marketed for children aged 8+ but I would say that children under 12 years old would need a good bit of help with it. On the positive side, my daughter LOVED making it and adores the end result, which looks just like the picture on the box, only it’s not purple, it’s pink.

In case, you are reading this because you are struggling with the instructions, I’ll save you visiting YouTube and I’ll tell you what we did.

  1. Add cold water gradually to the plaster powder until it is quite thick. Pour it into the plastic egg-shaped mould, making sure you cover as much edge as possible.
  2. Sprinkle some of the Potassium Aluminum power on the top flat part of the egg and leave aside overnight for the plaster to dry completely.
  3. The instructions say to stir in 117ml of potassium aluminum into 473ml of water. I found this very confusing as generally I just measure liquids in ml and the potassium aluminum is powder. I emptied the remaining potassium aluminum into the measuring jug and it came to the level of 55ml (which is approx half of what I am told to measure in the instructions?!) and I added this to 235ml of very hot water.
  4. Stir until this is completely dissolved
  5. Again, the instructions are a bit confusing at this point as they say ‘pour an equal amount of water and 20-30 drops of food colouring into a jar’ I get the feeling the manufacturer just copied instructions of any geode making kit into these instructions. If I’d watered down the food colouring, which is provided anymore, the geode would have been very pale pink. I just added all the food colouring provided to the potassium aluminum and water. On a side note, this kit only comes with the possibility of making a purple/pink geode, but I reckon that if you wanted one in a different colour, you could just use regular food colouring that you have at home.Toy Review Create a Geode Science Kit
  6. Let this mix sit for 30 minutes to cool
  7. Remove your dried plaster from the egg mould and gently lower it into the solution.
  8. Don’t touch it for a minimum of 12 hours. The longer you leave it, the bigger the crystals!Toy Review Create a Geode Science Kit

Apart from the instructions being confusing, the kit had everything that was needed in it and my daughter loves the fact that she now has a pair of science safety goggles, which appear to be good quality.

She really enjoyed watching her crystals grow through our glass jar. If you want your plaster to be as indisturbed as possible for 12 hours, I’d recommend doing it in a clear jar, so your children can watch what is changing, without having to lift the plaster in and out multiple times. We only had the patience to wait 12 hours – I wonder if much more would have grown if it had been left in the solution for longer.
